Description

Technical Field

[0001] The invention relates to the technical field of strapping tape production equipment, in particular to a conveying device for strapping tape production. Background Art

[0002] The strapping belt production conveyor is a part of the strapping belt production line, which is used to wind the produced strapping belt for subsequent packaging and use. This equipment is commonly found in plastic product processing plants and is used to improve the production efficiency and quality of strapping belts.

[0003] However, the existing technology still has major deficiencies, such as:

[0004] In the current strapping tape production process, operators usually need to manually wind the strapping tape onto the conveyor roller. In this process, since the conveyor roller rotates continuously and the strapping tape needs to have a certain inclination angle, the operator's hand is easily caught in the roller, which can cause severe injuries such as squeezing and strangulation. In view of this, in combination with existing related equipment, the applicant has invented a conveying device for strapping tape production, the main purpose of which is to eliminate the above-mentioned safety hazards, ensure the personal safety of operators while ensuring that the strapping tape can be produced and conveyed normally, greatly reduce the probability of work-related accidents, and create a safer and more reliable operating environment for strapping tape production operations. Summary of the invention

[0005] The object of the present invention is to provide a conveying device for producing strapping tape to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A conveying device for producing strapping tapes comprises a bracket on which a power roller, a plurality of transverse rollers and a plurality of longitudinal rollers are rotatably arranged, and further comprises a transverse assembly and a longitudinal assembly. The transverse roller generates a transverse displacement on the bracket via the transverse assembly, and the longitudinal roller generates a longitudinal displacement on the bracket via the longitudinal assembly.

[0012] Preferably, the transverse assembly comprises a transverse guide rail fixedly arranged on the bracket, a transverse slide plate is slidably arranged on the transverse guide rail, and the transverse roller is rotatably arranged on the transverse slide plate;

[0013] The bracket is fixedly provided with a second longitudinal guide rail, the second longitudinal guide rail is slidably provided with a second guide plate, the second guide plate is provided with a second guide groove, the transverse slide is rotatably provided with a second guide wheel, and the second guide wheel is rotatably provided in the second guide groove;

[0014] The second guide plate is fixedly connected to the lead screw nut.

[0015] Preferably, it also includes a pressing assembly, which includes a pressing guide rail fixedly arranged on the bracket, a pressing support rod fixedly arranged on the pressing guide rail, a plurality of pressing rods slidably arranged on the pressing support rod, a plurality of pressing rods are rotatably arranged on the pressing rods, and a spring is sleeved on the pressing rod.

[0016] Preferably, a telescopic cylinder is provided on one side of the pressing guide rail, and a movable end of the telescopic cylinder is fixedly connected to the pressing support rod.

[0017] Preferably, it further comprises a fixed axis assembly, wherein the fixed axis assembly comprises a plurality of fixed axis guide rails fixedly arranged on the bracket, an axis support seat is slidably arranged on the fixed axis guide rails, and a bearing is fixedly arranged in the axis support seat;

[0018] A slide bar is fixedly arranged on the bracket, a slider is slidably arranged on the slide bar, the slider is fixedly connected to a plurality of shaft support seats, and a compression spring is sleeved on the slide bar.

[0019] Preferably, a flexible tube is fixedly provided on the bracket, a flexible shaft is provided in the flexible tube, one end of the flexible shaft is fixedly connected to the pressing support rod, and the other end of the flexible shaft is fixedly connected to the slider.

[0020] Preferably, a plurality of weight-reducing holes are provided on the second guide plate;

[0021] A driving motor is fixedly arranged on the bracket, and power is transmitted between the power roller and the driving motor via a pulley set.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Through the coordinated design of the longitudinal and transverse components, the operator does not need to manually wind the strapping tape onto the conveyor roller. Driven by the stepper motor, lead screw, lead screw nut and other components, the longitudinal roller moves along a specific trajectory, driving the strapping tape to produce vertical stretching and angle deflection; under the action of the corresponding structure, the transverse roller cooperates with the longitudinal roller to make the strapping tape produce a specific angle deflection. The entire process does not require manual winding, eliminating the risk of the operator's hand being caught in the roller, causing squeezing, strangulation and other injuries, greatly ensuring the personal safety of the operator and significantly reducing the probability of work-related accidents.

[0024] 2. During the descent process, the longitudinal roller can produce lateral displacement through the constraint of the first guide groove on the first guide wheel, so that the strapping belt produces an angle deflection when it is vertically stretched; the lateral component works in conjunction with the longitudinal component to make the strapping belt between the lateral roller and the longitudinal roller produce a specific angle deflection. This multi-angle stretching method can make the strapping belt more evenly stressed during the stretching process, further optimize the stretching effect, help improve the quality and performance of the strapping belt, and meet the higher requirements of the production process for the quality of the strapping belt.

[0025] 3. In order to solve the problem that the bending moment caused by the stretching of the strapping tape during the operation of the longitudinal roller cantilever setting affects the stability and service life of the equipment, a fixed axis assembly is introduced. When the transverse roller and the longitudinal roller reach the working position and the telescopic cylinder drives the pressing assembly to press the material, the original cantilever structure of the longitudinal roller is changed into a partial support structure through the coordinated action of the flexible shaft, slider, shaft support seat and bearing and other components, which reduces the bending moment of the longitudinal roller caused by the stretching of the strapping tape, improves the stability and service life of the longitudinal roller, ensures that the device can operate stably for a long time, and improves the production quality of the strapping tape.

[0026] 4. Both the horizontal and vertical components are driven by the same lead screw, and the pressing component and the fixed axis component also adopt a linkage design, which simplifies the driving structure, improves the overall coordination and stability of the device, and makes the operation of the device more stable and reliable.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-19 , the present invention provides a technical solution:

[0049] Embodiment 1:

[0050] A conveying device for strapping tape production, the structural design of which is intended to achieve efficient and safe conveying and stretching of strapping tape. The specific structure is as follows, Figure 1 As shown, the device includes a solid support frame 1, which serves as the basic supporting structure of the entire conveying device.

[0051] On the bracket 1, a power roller 2, a plurality of transverse rollers 3 and a plurality of longitudinal rollers 4 are arranged by means of rotational connection. These rollers assume different functions in the entire conveying process. The power roller 2 provides power for the conveying of the strapping tape, while the transverse rollers 3 and the longitudinal rollers 4 play a key role in the position adjustment and stretching of the strapping tape. At the same time, the device is also equipped with a transverse component 300 and a longitudinal component 400. The transverse roller 3 can generate a transverse displacement on the bracket 1 with the help of the transverse component 300, and the longitudinal roller 4 can achieve a longitudinal displacement on the bracket 1 with the help of the longitudinal component 400.

[0052] like Figure 4 , Figure 7-11As shown, the longitudinal assembly 400 is constructed. First, the first longitudinal guide rail 401 and the first guide plate 402 are fixed on the bracket 1, and the first guide plate 402 is provided with a first guide groove 403. The first longitudinal guide rail 401 provides a stable track for the sliding of the longitudinal slide 404, and the longitudinal slide 404 is slidably connected to the first longitudinal guide rail 401 through the slider 605, ensuring that the longitudinal slide 404 can move up and down smoothly along the first longitudinal guide rail 401.

[0053] The shape of the first guide groove 403 in this embodiment is set according to the path that the longitudinal guide rail needs to run. The shape of the first guide groove 403 of different devices may be different. In this application, Fig. 9 As shown, the first guide groove 403 includes three parts from top to bottom, namely: an initial section, a guide section and a working section. When the first guide wheel 407 is in the initial section, the longitudinal roller 4 will not produce a lateral displacement and will only move downward. When the first guide wheel 407 is in the guide section, the longitudinal roller 4 will produce a certain lateral displacement while moving downward. When the first guide wheel 407 is in the working section, the longitudinal roller 4 will only move downward. By replacing different first guide plates, the longitudinal roller can produce lateral or longitudinal movements of different distances.

[0054] A plurality of translation guide rails 405 are provided on the longitudinal slide 404 by means of bolts or other fixing means. A translation slide 406 is also installed on the translation guide rail 405 by means of a suitable fixing means, and a first guide wheel 407 is rotatably provided on the translation slide 406 by means of a rotation connection structure such as a bearing. The first guide wheel 407 is closely matched with the first guide groove 403 on the first guide plate 402, and the first guide wheel 407 is rollingly provided in the first guide groove 403, so that the translation slide 406 can move accordingly according to the shape of the first guide groove 403 during the movement of the longitudinal slide 404. The axis of the longitudinal roller shaft 4 is rotatably provided on the translation slide 406 by means of a rotation connection component such as a bearing, so that the longitudinal roller shaft 4 moves along with the movement of the translation slide 406.

[0055] In terms of power drive, in order to realize the lifting and translation movement of the longitudinal roller shaft 4, a stepper motor 7 is arranged on the bracket 1. The shaft of the stepper motor 7 is tightly connected to the lead screw 8 through a coupling to ensure that the stepper motor 7 can stably drive the lead screw 8 to rotate when it rotates. A lead screw nut 9 is adapted to be arranged on the lead screw 8, and the lead screw nut 9 is tightly connected to the longitudinal slide 404 by bolt fixing or the like. In this way, when the stepper motor 7 is started, its rotation is transmitted to the lead screw nut 9 through the lead screw 8, thereby driving the longitudinal slide 404 to slide accordingly on the first longitudinal guide rail 401.

[0056] In the initial state, the longitudinal roller 4 is at the highest point, and the entire conveying device is in a ready-to-work state. When the strapping tape needs to be stretched for transportation, the operator first pulls the strapping tape in accordance with the Figure 1 The stepper motor 7 is placed horizontally on the transverse roller 3 in the manner shown. Subsequently, the operator issues a start command to the stepper motor 7 through the operation panel set on the bracket 1. After receiving the command, the stepper motor 7 starts to rotate, and its rotation drives the lead screw 8 connected to it to rotate. The rotation of the lead screw 8 causes the lead screw nut 9 to move along the lead screw 8. Since the lead screw nut is fixedly connected to the longitudinal slide 404, the longitudinal slide 404 slides downward along the first longitudinal guide rail 401 under the drive of the lead screw nut, thereby changing the device from the initial state to the working state, that is, from Fig. 9 The status shown changes to Fig.11 Status shown.

[0057] During the descent of the longitudinal slide 404, the first guide wheel 407 on the translation slide 406 slides in the first guide groove 403 of the first guide plate 402. The shape of the first guide groove 403 is as follows: Figure 9-11 As shown, when the longitudinal slide 404 reaches the middle and lower part of the first longitudinal guide rail 401, due to the shape constraint of the first guide groove 403, the first guide wheel 407 will be subjected to the force of the guide groove, thereby guiding the translation slide 406 on the longitudinal slide 404 to produce a lateral displacement on the translation guide rail 405. This lateral displacement causes the longitudinal roller 404 to move along the longitudinal roller 404. Figure 5 With this design, the operator does not need to manually wind the strapping tape, which greatly avoids the dangers that may be caused by manual operation. In addition, while the longitudinal roller 4 is descending, it can also produce a certain lateral displacement under the guidance of the first guide plate 402, so that when the strapping tape is vertically stretched, it can produce the following Figure 5 The angle deflection shown. This angle deflection can better stretch the strapping tape and help improve the quality and performance of the strapping tape.

[0058] In addition, a driving motor 201 is fixedly arranged on the bracket 1, and power is transmitted between the power roller 2 and the driving motor 201 through a pulley set 202. The driving motor 201, as a power source, transmits power to the power roller 2 through the pulley set 202, so that the power roller 2 can rotate continuously and stably, thereby providing necessary power support for the conveying of the strapping belt, ensuring that the strapping belt can be smoothly conveyed and stretched on the entire conveying device.

[0059] Embodiment 2:

[0060] This embodiment is optimized on the basis of the first embodiment, and a transverse component 300 is added. Through the cooperation of the transverse component 300 and the longitudinal component 400, the strapping belt between the transverse roller 3 and the longitudinal roller 4 is deflected at a specific angle, further improving the stretching effect of the strapping belt and meeting the production requirements of higher quality.

[0061] like Figure 7 , Figure 8 as well as Figure 12-15 As shown, a transverse guide rail 301 is fixedly provided on the bracket 1. A slidably connected transverse slide plate 302 is provided on the transverse guide rail 301, and this sliding connection ensures that the transverse slide plate 302 can smoothly move laterally on the transverse guide rail 301.

[0062] The transverse roller 3 is rotatably arranged on the transverse slide plate 302 through a rotation connection structure such as a bearing. In this way, the transverse roller 3 can maintain its own rotation function and change its position as the transverse slide plate 302 moves.

[0063] A second longitudinal guide rail 303 is also fixedly provided on the bracket 1. A second guide plate 304 is mounted on the second longitudinal guide rail 303 in a sliding connection manner, so that the second guide plate 304 can move up and down along the second longitudinal guide rail 303. A second guide groove 305 is provided on the second guide plate 304, and the shape and position design of the groove play a key guiding role in the movement of subsequent components.

[0064] The shape of the second guide groove 305 in this embodiment is set according to the path that the longitudinal guide rail needs to run. The shape of the second guide groove 305 of different devices may be different. In this application, Figure 7 and Fig.13 As shown, the second guide groove 305 is divided into an initial section, a guide section and a working section from top to bottom, and the transverse roller 3 generates a transverse displacement in the guide section.

[0065] By replacing different second guide plates, the transverse roller can generate transverse movements of different distances.

[0066] On the transverse slide plate 302, a second guide wheel 306 is rotatably arranged through a rotation connection mode such as a bearing. The second guide wheel 306 is rollingly arranged in the second guide groove 305 of the second guide plate 304, thereby establishing a motion relationship between the transverse slide plate 302 and the second guide plate 304.

[0067] The second guide plate 304 is closely connected to the screw nut 9 for controlling the movement of the longitudinal slide plate 404 in the first embodiment by bolt connection or other fixing methods. In this way, the movement of the screw nut 9 can drive the second guide plate 304 to move synchronously.

[0068] In order to optimize the performance of the device and reduce the overall weight, a number of weight-reducing holes 3041 are provided on the second guide plate 304. The arrangement of these weight-reducing holes 3041 effectively reduces the overall weight of the device, reduces energy consumption during the driving process, and improves the flexibility of the device operation without affecting the structural strength and function of the second guide plate 304.

[0069] Initial state

[0070] like Figure 1 , Figure 3 , Figure 7 and 12 As shown, in the initial state, the transverse roller 3 is located away from the power roller 2, the entire device is in a ready-to-work state, and the strapping belt has not yet been placed.

[0071] like Figure 1 As shown, after the operator places the strapping tape horizontally, the stepper motor 7 is started through the operation panel. The stepper motor 7 rotates to drive the lead screw 8 to rotate. Since the lead screw nut is threadedly matched with the lead screw 8 and is fixedly connected to the longitudinal slide 404, the lead screw nut 9 begins to descend when the lead screw 8 rotates, thereby driving the longitudinal slide 404 to slide downward along the first longitudinal guide rail 401. As described in the first embodiment, the longitudinal roller 4 begins to descend and completes the preliminary process of stretching and winding the strapping tape.

[0072] At the same time, because the second guide plate 304 is fixedly connected to the lead screw nut 9, the second guide plate 304 will be driven by the lead screw nut to synchronously descend along the second longitudinal guide rail 303. During the descent process, since the second guide wheel 306 is rollingly arranged in the second guide groove 305, when the second guide plate 304 descends to a specific position, the special shape of the second guide groove 305 generates a lateral restraining force on the second guide wheel 306. This force causes the second guide wheel 306 to drive the transverse slide plate 302 to generate a certain transverse displacement on the transverse guide rail 301, thereby causing the transverse roller shaft 3 to move in a direction close to the power roller shaft 2.

[0073] Through such coordinated movements, Figure 2 and Figure 5 As shown, the strapping tape between the transverse roller 3 and the longitudinal roller 4 has a certain angle deflection. This angle deflection can make the strapping tape more evenly stressed during the stretching process, further optimize the stretching effect, improve the quality and performance of the strapping tape, and meet the higher requirements of the production process for the quality of the strapping tape. Moreover, in this embodiment, the transverse component 300 and the longitudinal component 400 are driven by the same screw 8, which simplifies the driving structure and improves the overall coordination and stability of the device.

[0074] Embodiment three:

[0075] This embodiment is based on the previous embodiment, and further optimizes the conveying device for strapping production, and adds a pressing component 5. The main function of the pressing component 5 is to squeeze and position the strapping belt to ensure the stability of the strapping belt during the stretching process, and at the same time, it can also realize additional functions such as printing processing to enhance the added value of the product.

[0076] like Figure 2 , Figure 6 , Fig.16 and Fig.17 As shown, a press guide rail 501 is provided on the bracket 1 by reliable fixing methods such as welding and bolt connection. A press support rod 502 is also fixedly provided on the press guide rail 501 by bolt connection or the like. This fixed connection between the press support rod 502 and the press guide rail 501 provides a stable foundation for the installation and movement of subsequent components.

[0077] A plurality of pressing rods 503 are arranged on the pressing rod 502, and these pressing rods 503 are connected to the pressing rod 502 in a sliding manner. Specifically, a sliding groove or a guide hole adapted to the pressing rod 503 is provided on the pressing rod 502, and the pressing rod 503 can smoothly slide linearly therein, thereby ensuring that the pressing rod 503 can flexibly adjust its position according to actual needs.

[0078] On the pressing rod 503, a pressing roller shaft 504 is rotatably arranged through a bearing rotation connection structure. This rotation connection mode enables the pressing roller shaft 504 to rotate freely, so that when the strapping tape is squeezed, the movement of the strapping tape will not be hindered, and functions such as printing can also be achieved.

[0079] A spring 505 is sleeved on each pressing rod 503. The spring 505 is arranged between the pressing roller shaft 504 and the pressing support rod 502, and will not affect the rotation of the pressing roller shaft 504. The arrangement of the spring 505 provides elastic pressure for the pressing roller shaft 504, so that it can better adapt to strapping tapes of different thicknesses and always maintain the squeezing effect on the strapping tape.

[0080] A telescopic cylinder 506 is installed on one side of the press guide rail 501. The movable end of the telescopic cylinder 506 is fixed together with the press support rod 502 by bolt connection or the like. This connection ensures that the telescopic cylinder 506 can effectively drive the press support rod 502 to move linearly along the press guide rail 501.

[0081] When the transverse roller 3 and the longitudinal roller 4 have not yet reached the working position, the pressing assembly 5 is in an initial standby state. At this time, the telescopic cylinder 506 is in a contracted state, the pressing support rod 502 is located away from the transverse roller 3, and there is no contact between the pressing roller 504 and the strapping belt.

[0082] When the transverse roller 3 and the longitudinal roller 4 reach the working position through the corresponding driving structures, the operator sends a driving instruction to the telescopic cylinder 506 through the operation panel.

[0083] After receiving the command, the piston inside the telescopic cylinder 506 starts to move under the action of hydraulic pressure or gas pressure, driving the movable end to extend. Since the movable end of the telescopic cylinder 506 is fixedly connected to the press rod 502, the press rod 502 moves linearly along the press guide rail 501 under the push of the movable end of the telescopic cylinder 506.

[0084] As the pressing rod 502 moves, when it reaches the top of the transverse roller 3, the pressing roller 504 also reaches the top of the strapping tape. Since the pressing rod 503 is sleeved with a spring 505, the pressing rod 503 drives the pressing roller 504 to move downward under the elastic force of the spring 505, thereby squeezing the strapping tape on the transverse roller 3. In this way, the strapping tape is stably positioned on the transverse roller 3, avoiding deviation or shaking during the stretching process, thereby ensuring the stability of the stretching process and the product quality.

[0085] At the same time, in order to realize the printing processing of the strapping tape, a pattern can be set on the surface of the pressing roller 504. When the pressing roller 504 squeezes the strapping tape, as the strapping tape moves, the pattern on the surface of the pressing roller 504 will leave an imprint on the surface of the strapping tape, completing the printing processing. This printing function not only increases the beauty of the strapping tape, but also improves the anti-slip performance of the strapping tape to a certain extent, etc., to meet the needs of different customers.

[0086] Embodiment 4:

[0087] In the actual strapping production process, since the longitudinal roller 4 is cantilevered, bending moment will be generated due to the stretching of the strapping during operation, which may affect the stability and service life of the equipment. Therefore, the fixed axis assembly 6 is introduced in this embodiment to provide support for the longitudinal roller 4 to improve its stress condition. At the same time, the fixed axis assembly 6 and the pressing assembly 5 are linked by the flexible shaft 608, so that the movement of the entire device is more coordinated.

[0088] like Figure 2 , Figure 3 , Fig.18 and Fig.19 As shown, a plurality of transverse fixed axis guide rails 601 are arranged on the bracket 1 by a firmly fixed connection. These fixed axis guide rails 601 provide a guide and support basis for the subsequent movement of the shaft support seat 602. On the fixed axis guide rails 601, the shaft support seat 602 is arranged by a sliding connection, and the shaft support seat 602 can slide linearly along the fixed axis guide rails 601 so as to adjust the position as needed.

[0089] A bearing 603 is fixedly arranged inside the shaft support seat 602 by a suitable fixing method (such as press fitting, interference fit, etc.). The outer ring of the bearing 603 and the shaft support seat 602 adopt an interference fit to ensure that the position of the bearing 603 in the shaft support seat 602 is stable and will not rotate or move relative to each other; and the inner ring of the bearing 603 and the rotating shaft of the longitudinal roller shaft 4 are clearance fit, which allows the rotating shaft of the longitudinal roller shaft 4 to move flexibly in the bearing 603, and also facilitates its fit or separation with the bearing 603, thereby providing good support and rotation performance for the longitudinal roller shaft 4.

[0090] A slide bar 604 is also fixedly arranged on the bracket 1, and the slide bar 604 provides a guide for the movement of the slider 605. The slider 605 is arranged on the slide bar 604 in a sliding connection manner, and can slide freely on the slide bar 604. The slider 605 is fixedly connected to the plurality of shaft support seats 602 by bolt connection or other reliable connection methods, so that the movement of the slider 605 can drive the shaft support seats 602 to move synchronously. A compression spring 606 is sleeved on the slide bar 604, one end of the compression spring 606 abuts against the slider 605, and the other end abuts against the fixed stopper on the slide bar 604, providing elastic restoring force for the reset of the slider 605.

[0091] In order to realize the linkage of the fixed axis assembly 6 and the pressing assembly 5 and save the manufacturing cost of the device, a flexible tube 607 is fixedly arranged on the bracket 1. A flexible shaft 608 is arranged inside the flexible tube 607, one end of the flexible shaft 608 is fixedly connected to the pressing support rod 502 by bolt connection or other means, and the other end is fixedly connected to the slider 605. The flexible shaft 608 can be flexibly extended and retracted in the flexible tube 607, and its flexible characteristics allow it to adapt to different motion trajectories and component position changes while transmitting motion.

[0092] In the initial state of the device, the shaft support seat 602 is at a position away from the rotation axis of the longitudinal roller shaft 4, the slider 605 is located at one end of the slide bar 604, the flexible shaft 608 is partially retracted in the flexible tube 607, the compression spring 606 is in a pre-compression state, and the longitudinal roller shaft 4 is cantilevered and not supported by the shaft support seat 602. At this time, the device is waiting for the placement of the strapping tape and subsequent operations.

[0093] When the transverse roller 3 and the longitudinal roller 4 reach the working position, the telescopic cylinder 506 extends to drive the material pressing assembly 5 to press the material (as described in the third embodiment), and the movable end of the telescopic cylinder 506 starts to move. Since one end of the flexible shaft 608 is fixedly connected to the material pressing support rod 502, the movable end of the telescopic cylinder 506 drives the flexible shaft 608 to move.

[0094] As one end of the flexible shaft 608 is pulled out of the flexible tube 607, the other end thereof pulls the slider 605 to move on the slide bar 604. The slider 605 moves along the slide bar 604 toward the flexible tube 607. Since the slider 605 is fixedly connected to the shaft support seat 602, the shaft support seat 602 moves toward the rotation axis direction of the longitudinal roller shaft 4 on the fixed axis guide rail 601.

[0095] As the shaft support seat 602 moves, the rotating shaft of the longitudinal roller 4 will eventually be sleeved in the bearing 603. At this time, the inner ring of the bearing 603 provides support for the rotating shaft of the longitudinal roller 4, and the original cantilever structure of the longitudinal roller 4 is changed into a partial support structure, thereby reducing the bending moment of the longitudinal roller 4 caused by the stretching of the packaging belt, and improving the stability and service life of the longitudinal roller 4.

[0096] When the telescopic cylinder 506 contracts, it drives the press rod 502 to move in the opposite direction. At this time, the flexible shaft 608 at one end of the slider 605 is pulled out of the flexible tube 607 under the elastic restoring force of the compression spring 606. At the same time, the slider 605 is reset along the slide bar 604 toward the flexible tube 607 under the action of the compression spring 606.

[0097] As the slider 605 is reset, the shaft support seat 602 will also move along the fixed axis guide rail 601, and finally disengage from the rotating shaft of the longitudinal roller 4, so that the longitudinal roller 4 returns to the cantilever state, ready for the next working cycle.

[0098] By setting the above-mentioned fixed axis assembly 6, the stress problem of the cantilever setting of the longitudinal roller 4 is effectively solved. At the same time, the linkage with the pressing assembly 5 is realized through the flexible axis 608, so that the movement of the whole device is more coordinated and orderly, the reliability of the equipment and the convenience of operation are improved, and the stability and efficiency of the strapping tape production process are ensured.

[0099] Meanwhile, in this embodiment, the transverse roller shaft 3, the longitudinal roller shaft 4 and the power roller shaft 2 are all hollow, and weight-reducing holes 3041 are opened on the end surfaces to reduce the bending moment generated by the roller shaft due to its own weight.

[0100] Working principle: During the use of the present invention, in the initial state, the longitudinal roller 4 is at the highest point, the transverse roller 3 is at a position away from the power roller 2, the pressing assembly 5 is in an initial standby state (the telescopic cylinder 506 is retracted, the pressing support rod 502 is away from the transverse roller 3, and the pressing roller 504 has no contact with the strapping tape), the shaft support seat 602 in the fixed axis assembly 6 is away from the rotating axis of the longitudinal roller 4, and the entire device waits for the strapping tape to be placed.

[0101] The operator places the strapping tape horizontally on the transverse roller 3, connects the end of the strapping tape to the material roller, and then starts the stepper motor 7 through the operation panel. The stepper motor 7 rotates to drive the screw 8 connected thereto to rotate. The screw nut 9 on the screw 8 is threadedly matched with the screw 8 and is fixedly connected to the longitudinal slide 404, thereby driving the longitudinal slide 404 to slide downward along the first longitudinal guide rail 401. During the descent of the longitudinal slide 404, the first guide wheel 407 on the translation slide 406 slides in the first guide groove 403 of the first guide plate 402. When the longitudinal slide 404 reaches the middle and lower part of the first longitudinal guide rail 401, it is constrained by the first guide groove 403, and the translation slide 406 generates a lateral displacement on the translation guide rail 405, so that the longitudinal roller 4 moves along a specific trajectory, driving the strapping tape to generate vertical stretching and angle deflection, without the need for manual winding, thereby improving the stretching effect.

[0102] When the longitudinal roller 4 descends, since the second guide plate 304 is fixedly connected to the screw nut 9, the second guide plate 304 will descend synchronously with the screw nut 9 along the second longitudinal guide rail 303. When the second guide plate 304 descends to a specific position, the second guide groove 305 generates a lateral restraining force on the second guide wheel 306 rolling therein, so that the second guide wheel 306 drives the transverse slide plate 302 to produce a lateral displacement on the transverse guide rail 301, thereby causing the transverse roller 3 to move in a direction close to the power roller 2, and cooperate with the longitudinal roller 4 to cause the strapping belt between them to produce a specific angle deflection, further optimizing the stretching effect. At the same time, the drive motor 201 drives the power roller 2 to rotate through the pulley group 202 to provide power for the strapping belt conveyor.

[0103] When the transverse roller 3 and the longitudinal roller 4 reach the working position, the operator sends a driving command to the telescopic cylinder 506 through the operation panel. The piston inside the telescopic cylinder 506 moves under the action of hydraulic pressure or pneumatic pressure, driving the movable end to extend, pushing the pressing support rod 502 to move linearly along the pressing guide rail 501. When the pressing support rod 502 reaches directly above the transverse roller 3, the pressing roller 504 on the pressing rod 503 moves downward under the elastic force of the spring 505, squeezing the strapping tape on the transverse roller 3, stably positioning the strapping tape on the transverse roller 3, and ensuring the stability of the stretching process. At the same time, if the surface of the pressing roller 504 is provided with a pattern, as the strapping tape moves, the pattern will leave an imprint on the surface of the strapping tape, completing the printing process.

[0104] When the transverse roller 3 and the longitudinal roller 4 reach the working position, the telescopic cylinder 506 extends to drive the material pressing assembly 5 to press the material, and one end of the flexible shaft 608 fixedly connected to the material pressing support rod 502 is pulled out from the flexible tube 607, pulling the slider 605 fixedly connected to the other end to move on the slide bar 604 toward the flexible tube 607. Since the slider 605 is fixedly connected to the shaft support seat 602, the shaft support seat 602 moves along the fixed axis guide rail 601 toward the rotation axis direction of the longitudinal roller 4, and finally the rotation axis of the longitudinal roller 4 is sleeved in the bearing 603 in the shaft support seat 602. The inner ring of the bearing 603 provides support for the rotation axis of the longitudinal roller 4, improves the cantilever stress condition of the longitudinal roller 4, and reduces the bending moment caused by the stretching of the strapping belt.

[0105] When the telescopic cylinder 506 contracts, the pressing support rod 502 moves in the opposite direction, and the flexible shaft 608 at one end of the slider 605 is pulled out of the flexible tube 607 under the elastic restoring force of the compression spring 606. The slider 605 is reset along the slide rod 604, and the shaft support seat 602 is disengaged from the rotating shaft of the longitudinal roller 4, and the longitudinal roller 4 returns to the cantilever state, preparing for the next working cycle.
