Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, specifically a bag-pulling machine that is easy to control in speed. Background Technology

[0002] On packaging production lines for food, pharmaceuticals, and daily necessities, the bag-pulling machine plays a crucial role in pulling packaging bags from the rolls and transporting them to the packaging station.

[0003] A bag-pulling machine with easy speed control typically consists of a drive unit, a tension adjustment mechanism, a speed monitoring sensor, an intelligent control system, and a human-machine interface. The drive unit uses a servo motor or a variable frequency motor to provide power for the bag-pulling action; the tension adjustment mechanism adjusts the tensile tension of the packaging bag in real time through elastic elements and pressure sensors; the speed monitoring sensor uses photoelectric or encoder technology to collect bag-pulling speed data in real time; the intelligent control system is based on a PLC or industrial computer and has multiple built-in speed regulation algorithms; the human-machine interface allows operators to intuitively set speed parameters and operating modes.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. The traditional manual bag-pulling method not only consumes a lot of manpower, but is also inefficient and cannot meet the needs of the explosive growth in parcel volume during peak business periods such as e-commerce shopping festivals. In view of this, we propose a bag-pulling machine that is easy to control the speed. Utility Model Content

[0005] The purpose of this invention is to provide a bag-pulling machine with easily controllable speed, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bag-pulling machine with easily controllable speed includes a mounting plate. A wire groove support block is fixedly mounted on the mounting plate. A cover support frame is fixedly mounted on the wire groove support block. A bag-pulling section cover is fixedly mounted on the cover support frame. A maintenance sealing plate is snap-fitted onto the bag-pulling section cover. A bag-pulling assembly is provided on the mounting plate. The bag-pulling assembly includes:

[0008] A pull rod is fixedly mounted on the mounting plate, a drive roller is rotatably mounted on the mounting plate, a motor is fixedly mounted on the mounting plate, and a drive pulley is fixedly mounted on the output end of the motor;

[0009] A drive pulley is fixedly mounted on the drive roller, a support plate is fixedly mounted on the mounting plate, and a reinforcing rod is fixedly mounted on the support plate;

[0010] The mounting plate is fixedly mounted with a foot support, the cover of the pull bag section is provided with a guide groove, and the driven shaft is rotatably mounted on the mounting plate.

[0011] In a further embodiment, a transmission belt is installed between the driving pulley and the drive pulley, and a packing conveyor belt is installed between the driving roller and the driven shaft.

[0012] In a further embodiment, multiple sets of the mounting plate, cable tray support block, cover support frame, pull-bag section cover, inspection sealing plate, tie rod, reinforcing rod, foot support, and guide groove are provided.

[0013] In a further embodiment, the support plate and reinforcing rod are disposed inside the bag conveyor belt, with the support plate attached to the inner top surface of the bag conveyor belt.

[0014] In a further embodiment, a guide assembly is provided on the cover of the pouch section. The guide assembly includes a mounting cylinder, on which the mounting cylinder is fixedly mounted. One end of a helical spring is fixedly mounted inside the mounting cylinder, and the other end of the helical spring is fixedly mounted with a mounting rod. A mounting bracket is fixedly mounted on the mounting rod, and a hinge bracket is fixedly mounted on the mounting bracket. A rubber roller is rotatably mounted on the hinge bracket. A limit tube is fixedly mounted on the cover of the pouch section, and a limit slide rod is fixedly mounted on the mounting bracket.

[0015] In a further embodiment, multiple sets of the mounting cylinder, helical spring, mounting rod, mounting bracket, hinge bracket, rubber roller, limiting tube, and limiting slide bar are provided.

[0016] In a further embodiment, the helical spring is disposed inside the mounting cylinder, the mounting rod slides inside the mounting cylinder, and the limiting slide rod slides inside the limiting tube.

[0017] Compared with the prior art, this utility model provides a bag-pulling machine with easy speed control, which has the following beneficial effects:

[0018] 1. This speed-controlled parcel-pulling machine is equipped with a parcel-pulling component to meet the high-efficiency operation requirements during peak logistics periods. This component, in conjunction with a servo motor, outputs high-torque power, which is transmitted to the drive roller via a synchronous belt drive between the drive pulley and the transmission pulley. This drives the parcel-pulling conveyor belt. The support plate and reinforcing rod are attached to the top inner side of the conveyor belt to form a rigid support, preventing the conveyor belt from sagging due to load fluctuations and ensuring smooth parcel transport. At the same time, the foot support keeps the entire parcel-pulling mechanism horizontal, thus meeting the high-efficiency operation requirements during peak logistics periods.

[0019] 2. This package-pulling machine, which facilitates speed control, is equipped with a guide component to enhance its applicability in various logistics sorting scenarios. This component, in conjunction with multiple sets of spiral springs inside the mounting cylinder, pushes the mounting rod, causing the rubber rollers on the hinge frame to push the sides of the package. The rotation of the rubber rollers reduces the frictional resistance of the package and adjusts its position, preventing the package from being squeezed and damaged due to excessive guide rigidity. At the same time, the sliding design of the limiting slide rod within the limiting tube, combined with the elastic compensation of the spiral springs, can adapt to packages of different widths and straighten skewed packages.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-7 This utility model provides a technical solution:

[0032] A bag-pulling machine with easy speed control includes a mounting plate 1, a wire groove support block 2 fixedly mounted on the mounting plate 1, a cover support frame 3 fixedly mounted on the wire groove support block 2, a bag-pulling section cover 4 fixedly mounted on the cover support frame 3, and a maintenance sealing plate 5 snapped onto the bag-pulling section cover 4.

[0033] In one embodiment of this utility model, a bag-pulling assembly 6 is provided on the mounting plate 1. The bag-pulling assembly 6 includes a pull rod 61, which is fixedly mounted on the mounting plate 1. A drive roller 62 is rotatably mounted on the mounting plate 1. A motor 63 is fixedly mounted on the mounting plate 1. A drive pulley 64 is fixedly mounted on the output end of the motor 63. A transmission pulley 65 is fixedly mounted on the drive roller 62. A support plate 67 is fixedly mounted on the mounting plate 1. A reinforcing rod 68 is fixedly mounted on the support plate 67. A foot support 610 is fixedly mounted on the mounting plate 1. The cover 4 has a guide groove 611. The driven shaft cylinder 612 is rotatably mounted on the mounting plate 1. A transmission belt 66 is installed between the driving pulley 64 and the transmission pulley 65. A bag-pulling conveyor belt 69 is installed between the driving roller 62 and the driven shaft cylinder 612. Multiple sets of mounting plate 1, wire groove support block 2, cover support frame 3, bag-pulling section cover 4, inspection sealing plate 5, pull rod 61, reinforcing rod 68, foot support 610 and guide groove 611 are provided. The support plate 67 and reinforcing rod 68 are set inside the bag-pulling conveyor belt 69. The support plate 67 is attached to the inner top surface of the bag-pulling conveyor belt 69.

[0034] In this embodiment, multiple sets of foot supports 610 are fixed to the bottom of the mounting plate 1. By adjusting the foot supports 610, the bag-pulling mechanism can be kept horizontally stable, ensuring a stable posture during package transport. Simultaneously, after the motor 63 starts, the drive pulley 64 drives the transmission belt 66 to rotate, which in turn drives the drive roller 62 to rotate. The bag-pulling conveyor belt 69 between the drive roller 62 and the driven shaft cylinder 612 then runs, achieving package traction. The pull rod 61 on the mounting plate 1 is used to support the bag-pulling section structure. The support plate 67 and the reinforcing rod 68 are located inside the bag-pulling conveyor belt 69, and support... The support plate 67 fits against the top inner side of the conveyor belt to form a rigid support surface, preventing the conveyor belt from sagging and deforming due to the weight of the packages. The guide groove 611 opened in the package pulling section cover 4 provides a guiding path for package transportation, ensuring that the packages enter the weighing area along the predetermined trajectory. When it is necessary to adjust the package pulling speed, the servo motor 63 can adjust the output speed in real time according to the instructions of the PLC control system. By converting the speed ratio between the drive pulley 64 and the transmission pulley 65, the rotation speed of the drive roller 62 is controlled, making the linear speed of the package pulling conveyor belt 69 adjustable to meet the efficiency requirements of different logistics scenarios.

[0035] In one embodiment of this utility model, a guide assembly 7 is provided on the pull-out section cover 4. The guide assembly 7 includes a mounting cylinder 71. The mounting cylinder 71 is fixedly installed on the pull-out section cover 4. One end of a helical spring 72 is fixedly installed inside the mounting cylinder 71. The other end of the helical spring 72 is fixedly installed on the mounting rod 73. A mounting frame 74 is fixedly installed on the mounting rod 73. A hinge frame 75 is fixedly installed on the mounting frame 74. A rubber roller 76 is rotatably installed on the hinge frame 75. A limit tube 77 is fixedly installed on the pull-out section cover 4. A limit slide rod 78 is fixedly installed on the mounting frame 74. Multiple sets of mounting cylinder 71, helical spring 72, mounting rod 73, mounting frame 74, hinge frame 75, rubber roller 76, limit tube 77, and limit slide rod 78 are provided. The helical spring 72 is located inside the mounting cylinder 71. The mounting rod 73 slides inside the mounting cylinder 71. The limit slide rod 78 slides inside the limit tube 77.

[0036] In this embodiment, when packages of different widths pass through, the side of the package squeezes the rubber roller 76, causing the mounting rod 73 to compress the helical spring 72. The limiting slide rod 78 slides synchronously within the limiting tube 77. Through the elastic compensation of the helical spring 72, the rubber roller 76 always maintains a flexible clamping force on the package. The rotation design of the rubber roller 76 can reduce the resistance of package transmission. At the same time, through the synergistic action of the rubber rollers 76 on both sides, the skewed package is straightened to the center position of the conveyor belt, avoiding damage to the corners of the package due to excessive guiding rigidity.

[0037] All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art, and will not be described in detail here.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
