Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic packaging, in particular to a belt feeding device of a packaging machine. BACKGROUND

[0002] In production, in order to facilitate the storage / transportation / sale / intermediate processing (such as electroplating, heat treatment, etc.) of tubular or belt-shaped materials (such as copper pipes, copper belts, aluminum pipes, aluminum belts), the materials often need to be wound on a drum, and after the winding of the materials is completed, the materials need to be promptly bundled and packaged.

[0003] In the prior art, for the bundling and packaging of wound metal materials (such as wound copper pipes, copper belts, aluminum pipes, aluminum belts, etc.), or because of the requirement for the strength of the packaging, or because the wound metal materials need to be packaged first and then sent into an annealing furnace for annealing, copper belts or steel belts need to be used as packaging belts, and need to be bundled with metal packaging buckles. During packaging, the packaging belts at both ends need to pass through the packaging buckles, and one end of the packaging belt also needs to be bent after passing through the packaging buckle to avoid the packaging buckle slipping off, and then the packaging buckle is pressed tightly by a locking buckle machine to make the packaging buckle tightly abut against the packaging belt, and finally the excess packaging belt is cut off by a cutting machine.

[0004] In the prior art, the automatic technology for bundling and packaging is mostly seen in buckle-free packaging machines. The buckle-free packaging machine does not need to use a packaging buckle, but melts the two ends of the packaging belt to connect the upper and lower stacked packaging belts together to complete the bundling and packaging. However, for metal packaging belts, the existing automatic packaging machines cannot achieve automatic packaging because the metal packaging belts need to be used in cooperation with metal packaging buckles, so the current way is still manual packaging.

[0005] For such packaging conditions that require packaging buckles and packaging belts, the manual packaging process involves operations such as taking a packaging buckle, threading a packaging belt, feeding a packaging belt, tightening a packaging belt, biting a packaging belt (also known as locking a packaging belt or engaging a packaging belt), and cutting a packaging belt. The process is complicated and inefficient, especially the feeding and threading of the packaging belt (feeding the packaging belt to the direction where the bundling path needs to be formed, and threading the packaging belt through a specific belt passage, which is a passage provided on the existing drum for the convenience of packaging). After the winding of the materials is completed, the weight of the materials is large and easy to roll, in order to ensure the safety of the bundling, the packaging operation is often performed when the wound materials are still on the drum, which limits the rotation of the materials and facilitates packaging and ensures safety. However, the existence of the drum makes it necessary for the packaging belt to be fed from one side of the drum to the other side, and it is necessary to first pass through the threading transition groove on the drum and then insert it into the belt passage to achieve accurate feeding and threading. Under higher requirements, the manual operation method, which is already inefficient, becomes even more inefficient. SUMMARY

[0006] The present application intends to provide a tape feeding device of a packing machine to solve the problem of low manual operation efficiency caused by manual tape feeding when packing is performed by using a packing buckle and a packing tape.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0008] A tape feeding device of a packing machine comprises a traction assembly for traction conveying of a packing tape, a guide clamp provided with a guide channel for guiding the tape feeding of the packing tape, and a rotary driver for rotating the guide clamp.

[0009] The principle and advantages of the present application are as follows: when the present application is adopted, the packing tape is moved or conveyed by the traction assembly, and the conveyed packing tape moves along the guide channel. In the present application, the guide clamp only needs to be rotated by a set angle, and the conveying direction of the packing tape can be aligned with the tape passing channel. Then, the packing tape is fed into the tape passing channel under the feeding of the traction assembly and the guidance of the guide clamp.

[0010] Preferably, as an improvement, the device further comprises a lifter for lifting the guide clamp.

[0011] Beneficial effects: the height position of the guide clamp can be adjusted by the setting of the lifter, thereby facilitating the accurate insertion of the packing tape into the tape passing channel based on fewer debugging times.

[0012] Preferably, as an improvement, the guide clamp can swing relative to the output end of the rotary driver, and a guide seat is connected to the guide clamp, close to the discharge end of the guide clamp, and used for cooperating with the adjacent rib plate on the winding drum.

[0013] Beneficial effects: the tape passing channel and the tape passing transition groove on the winding drum generally have 2, 4 or 6 (the tape passing channel and the tape passing transition groove are one-to-one corresponding and aligned in the prior art, i.e., the port of the tape passing channel is connected to the tape passing transition groove), but the winding drum cannot be ensured to stay at the same position every time after each rotation, resulting in that the guide clamp cannot be completely aligned with the tape passing channel, and thus it is difficult to achieve the accurate insertion of the packing tape.

[0014] The present application can swing the guide clamp and install the guide seat on the guide clamp. When the guide clamp approaches the tape passing channel under the action of the lifter, the guide seat guides the approaching process, thereby improving the probability of the packing tape on the guide clamp being aligned with the tape passing channel.

[0015] Preferably, as an improvement, a first elastic member is symmetrically arranged on both sides of the swinging center of the guide clamp, one end of the first elastic member is fixed on the guide clamp, and the other end of the first elastic member is fixed on the output end of the rotary driver.

[0016] Beneficial effects: The first elastic member is arranged to automatically reset the guide clamp after each swing.

[0017] Preferably, as an improvement, the cross-sectional width of the guide channel gradually decreases from the feeding end to the discharging end.

[0018] Beneficial effects: The continuously narrowing cross-sectional width of the guide channel calibrates the position of the packaging belt, which helps the packaging belt extending out of the guide channel to be accurately inserted into the belt passing channel under the cooperation of the guide seat and the first elastic member, further improving the efficiency of the packaging belt passing.

[0019] Preferably, as an improvement, the guide clamp comprises a guide part and a movable plate, the guide part is provided with a guide groove, a pusher is arranged on the guide part, the movable plate is arranged on the output end of the pusher, the pusher is used to drive the movable plate away from or close to the bottom of the guide groove, and the guide groove and the movable plate can enclose the guide channel.

[0020] Beneficial effects: When the packaging belt is not yet clamped by the packaging buckle, it needs to be pulled out of the belt feeding device. If the enclosing space of the guide channel cannot be released, the packaging belt cannot be pulled out. The pusher is arranged to adjust the cross-sectional width of the guide channel, which facilitates the control of the feeding of the packaging belt. When the packaging belt needs to be pulled out of the guide channel, the pusher drives the movable plate away from the guide part, which facilitates the pulling out of the packaging belt.

[0021] Preferably, as an improvement, the traction assembly comprises a driving wheel and a driven wheel, at least one of the driving wheel and the driven wheel can move to adjust the distance between the driving wheel and the driven wheel; a translator is arranged to drive the traction assembly and the guide clamp to translate along the width direction of the packaging belt, or a swing driver is arranged to drive the traction assembly and the guide clamp to swing away from the packaging belt.

[0022] Beneficial effects: The distance between the driving wheel and the driven wheel of the traction assembly can be adjusted, which can meet the feeding requirements of packaging belts with different thicknesses, and when the distance between the driving wheel and the driven wheel is large enough, the translator or the swing driver can drive the traction assembly and the guide clamp to translate or swing away from the packaging belt, which prepares for the tensioning of the packaging belt before the packaging buckle clamps it.

[0023] Preferably, as an improvement, the guide seat is slidingly connected to the guide clamp, and the guide seat can move close to or away from the guide clamp after sliding, and a second elastic member is arranged between the guide seat and the guide clamp.

[0024] Beneficial effects: in the process of the guide clamp approaching the passing channel, in order to avoid hard collision between the guide clamp and the winding drum, the second elastic member is designed, so that in the approaching process, the guide seat has contacted the passing transition groove before the guide clamp contacts the passing transition groove of the passing channel feeding end, thereby reducing the impact strength of the guide seat and the winding drum, and realizing the protection of the passing device when approaching the passing channel.

[0025] Preferably, as an improvement, the guide clamp is arranged eccentrically relative to the output center of the relative rotation driver.

[0026] Beneficial effects: the scheme makes the rotating path of the guide clamp longer, so that the conveying path of the packing belt moves along a larger circular arc radius, avoiding the bending of the metal packing belt due to too small radius.

[0027] Preferably, as an improvement, the guide clamp is provided with a position monitor, and the position monitor is used to monitor whether the packing belt is conveyed to a set position.

[0028] Beneficial effects: when the scheme is adopted, the existence of the position monitor realizes the monitoring of the position of the packing belt, so that the packing belt can be stopped by the controller after the packing belt accurately passes out of the guide channel.

[0029] The application further discloses a belt receiving device, which comprises a lifting receiving arm, a receiving clamp is arranged on the receiving arm, a receiving channel is arranged on the receiving clamp, the receiving channel of the receiving clamp can be enlarged or reduced, the receiving channel of the receiving clamp can clamp the packing belt after being reduced, and a trumpet-shaped receiving port is arranged at a feeding end of the receiving channel.

[0030] Beneficial effects: the belt receiving device is used for clamping the packing belt which passes out of the passing channel, and the packing belt can be pulled by the lifting function of the receiving arm, so that the automatic degree of the packing belt is improved.

[0031] Preferably, as an improvement, a second rotation driver is arranged on the receiving arm, the receiving clamp is arranged at an output end of the second rotation driver, and the second rotation driver is used to drive the receiving clamp to rotate.

[0032] Beneficial effects: The arrangement of the second rotary driver in the scheme can change the direction of the discharging end of the receiving channel of the receiving clamp, so that the end of the packing belt can be rotated by the second rotary driver during the process that the receiving clamp clamps the packing belt to move to the packing buckle, which can form a surrounding posture on one hand, and can prepare for the end of the packing belt to insert into the packing buckle again on the other hand, further improving the degree of automation.

[0033] Preferably, as an improvement, a second pusher is further installed on the output end of the second rotary driver, and the receiving clamp comprises a fixed clamping plate and a movable clamping plate, the fixed clamping plate is fixed on the output end of the second rotary driver, and the second pusher is used to drive the movable clamping plate away from or close to the fixed clamping plate.

[0034] Beneficial effects: The design of the scheme can enlarge or reduce the receiving channel of the receiving clamp to meet the clamping and releasing requirements of the packing belt.

[0035] The application further discloses a belt feeding and receiving system, which comprises the belt feeding device and the belt receiving device of the packing machine. BRIEF DESCRIPTION OF DRAWINGS

[0098] In combination Figure 19 And Figure 20 An application of a belt feeding device includes using the belt feeding device of the packing machine described in Embodiment One on an automatic packing machine to feed the packing belt in the automatic packing machine.

[0099] The embodiment also discloses an automatic packing machine, which comprises a belt feeding device, and further comprises a packing belt feeding device 7, a locking device 8, a packing buckle feeding device 9 and a belt receiving device. The locking device is located between the packing belt feeding device 7 and the belt feeding device, and the belt receiving device is located between the packing belt feeding device 7 and the locking device. The packing belt feeding device 7 is used for feeding or winding the packing belt. The locking device 8 comprises a tensioning mechanism 81, a clamping mechanism 82 and a cutting knife 83. The tensioning mechanism 81 is used for feeding the packing belt forward or winding the packing belt backward. When the packing belt is wound backward, the packing belt feeding device 7 winds the excess packing belt. The process of winding the packing belt backward is the process of tightening the space surrounded by the packing belt. The clamping mechanism 82 is used for clamping the packing buckle with the double-layer packing belt. After the packing buckle is clamped, the cutting knife 83 is used for cutting the excess packing belt. The packing buckle feeding device 9 is used for pushing the packing buckle to be used to a standby position. The standby position can facilitate the tensioning mechanism 81 to pass the end of the packing belt through the packing buckle in the standby position.

[0100] The whole process of the automatic packing belt is as follows: the packing belt feeding device 7 feeds the packing belt. Under the forward feeding of the tensioning mechanism 81 of the locking device 8, the packing belt passes through the packing buckle fed by the packing buckle feeding device 9 and continuously feeds forward to the belt feeding device. The belt feeding device drives the packing belt to insert into the belt passing channel 20. The tensioning mechanism 81 and the traction assembly 3 continuously feed the belt. After the packing belt extends from the discharge end of the belt passing channel 20, the packing belt is received by the belt receiving device. The belt receiving device pulls the end of the packing belt. Then, the belt receiving device pulls the packing belt close to the locking device 8 and the packing buckle feeding device 9 until the end of the packing belt pulled by the belt receiving device is inserted into the standby packing buckle on the packing buckle feeding device 9, and the packing belt is wound. Then, the rotating plate on the packing buckle feeding device 9 bends one end of the end of the packing belt passing through the packing buckle to the outside of the packing buckle, so that the packing belt is buckled on the packing buckle. Then, the tensioning mechanism 81 winds the packing belt backward to tighten the space surrounded by the packing belt until the packing belt is tight. Finally, the clamping mechanism 82 clamps the packing buckle, and the cutting knife 83 cuts the excess part of the packing belt, so that the automatic packing of the packing belt and the packing buckle is completed.
