Description

Technical Field

[0001] The technical solution relates to the technical field of guide belt frames of tape machines, and in particular to a large-frame vacuum guide belt frame mechanism. Background Art

[0002] The strapping machine is an automated strapping device used to strap items.

[0003] For example, Chinese patent CN201793029U discloses a baling frame device of a baling machine, including a fixed frame and a movable belt path that can move toward and away from the fixed frame, wherein the movable belt path is formed by bending an aluminum alloy profile at the lower left, upper left, upper right, and lower right, and the aluminum alloy profile is provided with a baling belt guide groove facing the opening of the fixed frame, and the inner circle side surface of the baling belt guide groove is inclined from the inside toward the center of the movable belt path.

[0004] The baling frame device of the above-mentioned baling machine is equipped with a belt frame track in the existing baling equipment for delivering the baling belt to the designated position. When the above-mentioned baling machine is used for baling, when the strapping belt is wide and has a large mass, it cannot be flattened when filled into the baling belt guide groove, resulting in insufficient baling and poor stability of the guide belt, which needs to be improved. Summary of the invention

[0005] In order to improve the problem of poor stability when guiding a belt with a large width and mass, the technical solution provides a large-frame vacuum guide frame mechanism.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A large frame vacuum tape guide frame mechanism, comprising a tape guide frame, the tape guide frame having a tape supply port, the tape supply port being used for feeding a tape, the tape guide frame having a tape guide groove along an inner frame wall, the tape guide groove being provided with a first tape feeding assembly and a second tape feeding assembly, the first tape feeding assembly and the second tape feeding assembly being distributed along the tape guide groove for feeding the tape along the tape guide groove;

[0008] The outer frame wall of the tape guide frame is provided with a through hole, and a fan is installed at the position of the tape guide frame corresponding to the through hole, and the fan is started to adsorb the strap onto the first tape delivery assembly and the second tape delivery assembly;

[0009] A mounting seat is provided at the upper end of the tape guide frame, and a transmission structure is provided on the mounting seat. The transmission structure is connected between the first tape feeding assembly and the second tape feeding assembly, and the transmission structure is used to enable the first tape feeding assembly and the second tape feeding assembly to cooperate with each other in tape feeding during operation.

[0010] Through the above technical scheme, when the large-frame vacuum guide frame mechanism is in normal use, a drawstring with a larger width and mass is used. The drawstring enters the guide groove from the belt supply port of the guide frame, and the guide belt is continuously fed in and conveyed by the first belt feeding assembly to the second belt feeding assembly, and then conveyed by the second belt feeding assembly to the other side of the belt supply port to send out the upper drawstring, so that a circle of drawstring is laid in the belt guide groove along the length direction, so that a layer of overlapping drawstring at the belt supply port is used for subsequent ironing and packaging. During this belt feeding process, the fan is always in operation. When the fan is operating, it drives the air on one side of the guide groove to flow through the through hole to the outside of the guide frame, so that the drawstring can be adsorbed on the first belt feeding assembly and the second belt feeding assembly during the conveying process. The vacuum suction design effectively prevents the drawstring from being offset or wrinkled, thereby improving the stability of the guide belt.

[0011] The mounting seat is installed on the upper end of the guide belt frame, and the transmission structure of the mounting seat is simultaneously arranged on the first belt feeding assembly and the second belt feeding assembly. The transmission structure coordinates the two belt feeding assemblies to maintain a synchronous conveying rate, thereby ensuring seamless connection of the belt between the two belt feeding assemblies and reducing the problem of belt wrinkles caused by rate mismatch, thereby making the two belt feeding assemblies more coordinated and the belt can be smoothly conveyed, thereby making the guide belt more stable.

[0012] Preferably, the first belt feeding assembly comprises a first roller, a plurality of transmission wheels 1 and a transmission belt 1, the rotation axis of the first roller is parallel to the rotation axis of the transmission wheel 1, and the transmission belt 1 is tightened between the first roller and the plurality of transmission wheels 1;

[0013] The second belt feeding assembly comprises a second roller, a plurality of second transmission wheels and a second transmission belt, the rotation axis of the second roller is parallel to the rotation axis of the second transmission wheel, the rotation axes of the second roller and the first roller are parallel to each other, and the second transmission belt is tensioned between the second roller and the plurality of second transmission wheels;

[0014] The transmission structure includes a synchronous wheel 1, a synchronous wheel 2 and a synchronous belt. The synchronous wheel 1 is coaxially arranged with the first roller, the synchronous wheel 2 is coaxially arranged with the second roller, and the synchronous belt is tensioned between the synchronous wheel 1 and the synchronous wheel 2 so that the first roller and the second roller rotate in coordination.

[0015] Through the above technical scheme, based on the fact that the rotation axis of the first roller in the first belt feeding assembly is parallel to the rotation axis of any transmission wheel one, and the first roller and multiple transmission wheels are all located in the same plane, a transmission belt one is tightened between the first roller and multiple transmission wheels one to form a closed-loop transmission system to realize power transmission, so that the first roller and multiple transmission wheels one operate in coordination, and the transmission belt one drives the adjacent belt forward and out, ensuring the accuracy of transmission. Based on the fact that the rotation axis of the second roller in the second belt feeding assembly is parallel to the rotation axis of any transmission wheel two, and the second roller and multiple transmission wheels two are all located in the same plane, the transmission belt two is tightened between the second roller and multiple transmission wheels two to form a closed-loop transmission system to realize power transmission, so that the second roller and multiple transmission wheels two operate in coordination, and the transmission belt two drives the adjacent belt forward and out, further ensuring the accuracy of transmission.

[0016] The synchronous wheel 1 is coaxially arranged with the first roller, and the synchronous wheel 2 is coaxially arranged with the second roller. The synchronous belt is tensioned between the synchronous wheel 1 and the synchronous wheel 2 to realize power transmission. Based on the fact that the rotation axes of the second roller and the first roller are parallel to each other, the rotation of the synchronous wheel 1 drives the first roller to rotate, and the rotation of the synchronous wheel 2 drives the second roller to rotate. The rotation speeds of the synchronous wheel 1 and the synchronous wheel 2 are the same, so that the first roller and the second roller rotate synchronously, thereby making the guide belt transmission of the first belt feeding assembly and the second belt feeding assembly more coordinated.

[0017] Preferably, the mounting seat includes two mounting plates and a mounting block, the mounting block is located at the bottom of the belt guide groove, and the mounting block has a space corresponding to the first roller and the second roller;

[0018] The transmission structure is arranged on one of the mounting plates, and the two mounting plates are arranged one by one on the opposite sides of the corresponding mounting blocks of the guide frame, and the mounting block is connected between the two mounting plates to achieve fixation.

[0019] Through the above technical solution, the mounting block is placed at the bottom of the belt guide groove, and sufficient clearance space is left corresponding to the positions of the first roller and the second roller to ensure that the rollers can run smoothly without obstruction. The mounting block can be supported on the relative inner walls on both sides of the belt guide groove to provide a supporting effect. The two mounting plates are located on the opposite sides of the belt guide frame corresponding to the mounting block position. One of the mounting plates is used for the installation of the transmission structure. The two mounting plates are connected to the mounting block after passing through the belt guide frame by bolts to form a stable frame structure, thereby enhancing the overall firmness of the mounting seat.

[0021] When the fixing seat changes its fixing position along the length direction of the long groove 1, the clamping wheel abuts against the synchronous belt to adjust the tension of the synchronous belt.

[0022] Through the above technical scheme, a pressure wheel is installed on the fixed seat of the mounting plate. Based on the fact that the pressure wheel is parallel to the rotation axis of the first roller, it is ensured that the pressure wheel will not affect the operation of the synchronous belt when adjusting the tension of the synchronous belt. The long groove allows the fixed seat to adjust the position of the bolt fixation along its length direction. When the fixed seat is close to the synchronous belt, the pressure of the pressure wheel against the synchronous belt is increased, so that the synchronous belt is tensioned and the synchronous belt is prevented from being too loose. When the fixed seat is away from the synchronous belt, the pressure of the pressure wheel against the synchronous belt is reduced, so that the synchronous belt is relaxed, so that the synchronous belt is prevented from being too tight and the adjustability of the synchronous belt is improved.

[0023] Preferably, an adjusting wheel is provided in the belt guide groove, and the belt guide frame is provided with two long grooves 2, which are located one-to-one on opposite sides of the belt guide frame along the rotation axis of the adjusting wheel, and the adjusting wheel changes its fixed position along the length direction of the long grooves 2. The adjusting wheel rests on the transmission belt 2 to adjust the tension of the transmission belt 2.

[0024] Through the above technical solution, an adjusting wheel is provided in the belt guide groove. Based on the fact that the adjusting wheel is parallel to the rotation axis of the second roller, it is ensured that the adjusting wheel will not affect the operation of the second transmission belt when adjusting the tension of the second transmission belt. The second long groove allows the adjusting wheel to adjust the fixed position along its length direction. When the adjusting wheel is close to the second transmission belt, the pressure of the adjusting wheel against the second transmission belt is increased, so that the second transmission belt is further tensioned to prevent the second transmission belt from being too loose. When the adjusting wheel is away from the second transmission belt, the pressure of the adjusting wheel against the second transmission belt is reduced, so that the second transmission belt is relaxed to prevent the second transmission belt from being too tight, thereby improving the adjustability and ensuring that the second transmission belt maintains appropriate tension during operation, thereby improving the transmission efficiency.

[0025] Preferably, the belt guide groove comprises four groove sections, which are respectively a bottom groove, a connecting groove, a top groove and a side groove;

[0026] The first belt conveyor assembly is arranged at positions corresponding to the bottom groove and the connecting groove, and the second belt conveyor assembly is arranged at positions corresponding to the top groove and the side groove;

[0027] A belt guide frame is arranged in the belt guide groove, and a plurality of belt guide frames are arranged. The plurality of belt guide frames are located at the connection between adjacent groove sections in a one-to-one correspondence and are used for guiding the belt conveying.

[0028] Through the above technical scheme, one end of the bottom groove is connected with the connecting groove, and the other end of the connecting groove away from the bottom groove is connected with the top groove, the top groove is located above the bottom groove and is arranged opposite to the bottom groove, and the other end of the top groove away from the connecting groove is connected with the side groove, and the position of the side groove is arranged opposite to the connecting groove. Through openings are left at the positions of the side groove and the bottom groove facing the belt supply port, so that the belt enters from the through opening of the bottom groove, and the first belt feeding assembly guides the movement of the belt located in the bottom groove and the connecting groove, and the second belt feeding assembly guides the movement of the belt located in the top groove and the side groove, and the belt is finally led out from the through opening of the side groove, and multiple belt guide frames are located one by one at the connection between adjacent groove sections, so that the belt guide frames can support the relative inner walls of the corresponding groove sections and guide the belt to pass through, thereby improving the smoothness of the guide belt.

[0029] Preferably, the belt guide frame has an arc guide surface, and the arc guide surface is used to transition the corners between adjacent groove sections to guide the belt.

[0030] Through the above technical solution, the arc guide surface of the guide belt frame is a transition surface with a certain curve curvature. When the belt passes through the guide belt frame, the arc guide surface contacts the belt surface so that it moves along the arc surface, reducing the friction and resistance of the right-angle corners of adjacent groove sections on the belt, so that the belt can maintain a continuous and stable movement state when passing through the arc guide surface.

[0031] Preferably, a tape outlet rack is further provided in the tape guide groove, and the tape outlet rack is located at one end of the side groove close to the tape supply port, and the tape outlet rack has a guide surface, and the guide surface is used to guide the tape to the tape supply port.

[0032] Through the above technical solution, the tape outlet frame is located at the position corresponding to the through-opening at the lower end of the side groove, close to the tape supply port. The guide surface of the tape outlet frame is an arc surface, and the arc surface has a certain inclination angle and smoothness. The guide surface can guide the belt to be smoothly led out to the tape supply port, thereby completing the tape outlet.

[0033] Preferably, the tape guide frame is provided with an adjustment device, the adjustment device is arranged corresponding to the first tape feeding assembly, the adjustment device comprises an adjustment seat and an adjustment rod, a sliding groove is provided on an end surface of one side of the adjustment seat close to the tape guide frame, and the adjustment rod is slidably connected in the sliding groove;

[0034] One of the transmission wheels has a supporting part at both ends along the rotation axis, and two adjusting devices are provided. The positions of the two adjusting devices correspond to the two supporting parts one by one, and the supporting part is embedded in the corresponding sliding groove. The supporting part has a supporting surface, and the adjusting rod is in contact with the supporting surface. When the adjusting rod slides, the adjusting rod pushes the transmission wheel to move to adjust the tension of the transmission belt.

[0035] Through the above technical solution, one end of the adjusting rod passes through the adjusting seat and is embedded in the sliding groove. The length direction of the sliding groove corresponds to the sliding direction of the adjusting rod. The abutment portion of the transmission wheel 1 is embedded in the sliding groove, and the abutment surface of the abutment portion faces one side of the adjusting rod along the sliding direction, so that the sliding rod can slide and abut against the abutment surface. When it is necessary to adjust the tension of the conveyor belt 1, the adjusting rod is driven to move in the sliding groove, and the adjusting rod pushes the abutment portion to move synchronously with the movement, so that the transmission wheel 1 moves to tighten or loosen the transmission belt 1. After the tension of the transmission belt reaches the requirement, the adjustment operation can be stopped and the position of the adjusting rod can be locked to limit its movement, thereby ensuring the normal transportation of the transmission belt 1, improving the adjustability, and ensuring that the transmission belt 1 maintains appropriate tension during operation, thereby improving the transmission efficiency.

[0036] Two adjusting devices are provided, based on the fact that the two ends of the transmission wheel along the rotation axis have abutment parts, and the abutment parts at the two ends correspond to the two adjusting devices one by one to maintain the balance of the two sides of the transmission wheel.

[0037] Preferably, a plurality of support rods are provided in the tape guide groove, and two ends of each of the support rods are fixed one-to-one to opposite inner walls in the tape guide groove along the tape feeding direction.

[0038] Through the above technical solution, when the width of the belt guide groove is designed to be compatible with the larger size of the belt, the relative side walls at the groove mouth of the belt guide groove are easily deformed inward, and both ends of each support rod are connected to the relative inner walls of the belt guide groove along the belt feeding direction to prevent the belt guide frame from deforming during the transportation process. The support rods have a supporting effect, thereby enhancing the structural strength of the belt guide frame.

[0039] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0040] 1. This technical solution provides a mounting seat at the upper end of the guide belt frame, and the transmission structure of the mounting seat is simultaneously provided on the first belt feeding assembly and the second belt feeding assembly. The transmission structure coordinates the two belt feeding assemblies to maintain a synchronous conveying rate, ensures seamless connection of the belt conveying between the two belt feeding assemblies, improves coordination, and enables the belt to be smoothly conveyed, thereby making the guide belt more stable;

[0041] 2. This technical solution provides through holes in the belt guide frame, and fans are installed at positions corresponding to the through holes in the belt guide frame. When the fans are in operation, they drive air flow, so that the belt can be adsorbed on the first belt feeding assembly and the second belt feeding assembly during transportation, thereby effectively preventing the belt from being deflected or wrinkled and improving the stability of the belt guide.

The first roller 41 is located at the connection between the top groove 17 and the connecting groove 16. There are three transmission wheels 42, one of which is located at one end of the bottom groove 15 close to the belt supply port 2, and the other two transmission wheels 42 are both located at the connection between the bottom groove 15 and the connecting groove 16.

After the adjusting rod 232 slides, it is fixed to the adjusting seat 231 by bolts so that the positions are relatively positioned. Changing the fixed position of the adjusting rod 232 is used to adjust the tension of the transmission belt 43. When the adjusting rod 232 slides to push the transmission wheel 42, the abutting pressure of the transmission wheel 42 on the transmission belt 43 increases, thereby improving the tension of the transmission belt 43. When the adjusting rod 232 slides in the opposite direction, the abutting pressure of the transmission wheel 42 on the transmission belt 43 decreases, thereby reducing the tension of the transmission belt 43.

[0064] The specific working process of this program is as follows:

[0065] The technical solution is to open a tape guide groove 3 in the tape guide frame 1, and the tape enters the bottom groove 15 from the tape supply port 2 of the tape guide frame 1. The first tape feeding component 4 guides the tape from the bottom groove 15 to the top groove 17 through the connecting groove 16. The second tape feeding component 5 guides the tape from the top groove 17 to the side groove 18 and then leads the tape out to the tape supply port 2, so that the led-out tape is stacked on top of the introduced tape for subsequent hot-stitching and packaging. The mounting seat 8 is installed on the upper end of the tape guide frame 1, and the transmission structure 9 of the mounting seat 8 is simultaneously arranged on the first tape feeding component 4 and the second tape feeding component 5. The transmission structure 9 coordinates the two tape feeding components to maintain a synchronous conveying rate, ensures seamless connection of the tape between the two tape feeding components, reduces the problem of tape wrinkles caused by rate mismatch, and thus makes the two tape feeding components more coordinated, the tape can be smoothly conveyed, and the stability of the guide tape is better.
