Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a packaging machine with a pre-compression structure. Background Technology

[0002] A pre-compression baler is a specialized piece of equipment that pre-compresses loose materials before baling. It is mainly used for processing lightweight, fluffy waste materials (such as waste paper, plastic bottles, foam, textiles, straw, etc.). Its core function is to reduce the volume of the material through the pre-compression device, thereby improving the efficiency of subsequent compression and ultimately forming high-density, regularly shaped bales that are easy to transport, store, and recycle.

[0003] According to a public announcement of a leveling and pre-compressing type single-box baler (publication number: CN220147629U), the above application includes a leveling and pre-compressing component. When placing tobacco leaves, the lead screw module drives the third electric hydraulic cylinder and the pre-compressing plate to reciprocate, leveling the tobacco leaves and preventing them from curling up. The pre-compressing plate moves downward to compress the tobacco leaves, reducing their volume and allowing more tobacco leaves to be placed in the available space. Compared with traditional manual baling, this baling method is simpler and more convenient to operate, more efficient, and has a better baling effect, while reducing labor intensity and labor costs.

[0004] However, in the aforementioned application, when operators put materials into the feeding hopper, it is easy for the materials to accumulate unevenly inside the hopper, resulting in localized accumulation. When the pre-compression device presses down, this uneven distribution will affect the uniformity of compression, leading to inconsistent density of the final bales and affecting the packaging quality. Uneven material accumulation not only reduces the pre-compression effect but may also increase the load on the pre-compression device, leading to increased equipment energy consumption and even affecting the service life of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a packing machine with a pre-compression structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a baling machine with a pre-compression structure, including a material cylinder, a support leg fixed to the bottom of the material cylinder, a base plate fixed to the bottom of the support leg, an electric slide rail installed at the bottom of the base plate, and a leveling component and a linkage component provided on the surface of the material cylinder;

[0007] The leveling component includes:

[0008] Skateboards are used to propel materials.

[0009] The mounting bracket is used to stabilize the motor.

[0010] Gear 1 is used to drive gear 2 and the rack.

[0011] Preferably, the slide plate is slidably connected to the inner wall of the material cylinder. A second cylinder is fixed to the bottom of the material cylinder, with its output end penetrating the material cylinder and fixed to the bottom of the slide plate. A mounting frame is fixed to the bottom of the slide plate, and a motor is fixed to the surface of the mounting frame. A gear is passed through and fixed to the output shaft of the motor, and the gear is rotatably connected to the bottom of the slide plate. A second gear is rotatably connected to the bottom of the slide plate, and a short rod is provided on the surface of the second gear. The short rod passes through the second gear and is fixedly connected to the second gear. The short rod is located away from the gear. One end of wheel two passes through the slide plate, and a short rod is rotatably connected to the slide plate. A stirring plate is fixed to the end of the short rod away from gear two. The bottom of the stirring plate is in contact with the top of the slide plate. A rack is slidably connected to the bottom of the slide plate. Gear two meshes with the rack. When the motor is turned on, gear one intermittently meshes with the rack and gear two, causing the rack to move back and forth, which in turn drives gear two to rotate back and forth. The short rod drives the stirring plate to rotate back and forth, which can prevent the material from accumulating in one place and improve the uniformity of the material in the barrel. When cylinder two is opened, it extends, thereby causing the slide plate to move upward and push out the packaged material.

[0012] Preferably, the linkage component includes a fixed column, which is fixed to the surface of the rack. The surface of the fixed column has a groove, and a movable column is slidably connected to the inner wall of the groove. A spring is fixed to the surface of the movable column, and the end of the spring away from the movable column is fixed to the inner wall of the groove. A short column is fixed to the bottom of the slide plate. When the rack reciprocates, the fixed column moves, and through the spring, the movable column continuously contacts and impacts the surface of the short column, causing the slide plate to vibrate and further improving the uniformity of material spreading.

[0013] Preferably, a connecting frame is fixed to the surface of the electric slide rail, a cylinder is fixed to the top of the connecting frame, the output end of the cylinder passes through the connecting frame, a pressure plate is fixed to the bottom of the output end of the cylinder, a stabilizing rod is fixed to the top of the pressure plate, the top of the stabilizing rod passes through the connecting frame, and the stabilizing rod is slidably connected to the connecting frame, which facilitates pre-pressing of the material.

[0014] Preferably, the surface of the first gear is provided with four teeth, which are divided into two groups and arranged in a circumferential array with the center of the first gear as the axis. The surface of the second gear is provided with half of the teeth. When the first gear rotates continuously, it can intermittently mesh with the rack and the second gear, so that the second gear can reciprocate through the rack.

[0015] Preferably, the ends of the movable column and the short column that are close to each other are both set to be arc-shaped, so as not to affect the normal movement of the rack.

[0016] Compared with the prior art, this utility model provides a packing machine with a pre-compression structure, which has the following beneficial effects:

[0017] 1. This baler with a pre-compression structure, through the set leveling component, when feeding materials, the motor is turned on, and gear one intermittently meshes with the rack and gear two, causing the rack to move back and forth, which in turn drives gear two to rotate back and forth. Through the short rod, the stirring plate is driven to rotate back and forth, which can prevent materials from piling up in one place and improve the uniformity of materials in the barrel. When the pre-compression baling is completed, the cylinder two is opened to extend, and the slide plate moves up, which can push out the baled materials for easy personnel to pick up.

[0018] 2. This baler with a pre-compression structure, through the set linkage components, when the rack moves back and forth, the fixed column moves, and the movable column continuously contacts and impacts the surface of the short column. The movable column can move back and forth into the slide groove through the spring, and at the same time the slide plate vibrates, further improving the uniformity of material spreading.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a baling machine with a pre-compression structure, including a material cylinder 1, a support leg 2 fixed to the bottom of the material cylinder 1, a base plate 3 fixed to the bottom of the support leg 2, an electric slide rail 4 installed at the bottom of the base plate 3, and a leveling component 8 and a linkage component 9 provided on the surface of the material cylinder 1; the leveling component 8 includes: a slide plate 80, a second cylinder 81, a fixing frame 82, a motor 83, a first gear 84, a rack 85, a short rod 86, a second gear 87, and a stirring plate 88.

[0026] The slide plate 80 is slidably connected to the inner wall of the material cylinder 1. A second cylinder 81 is fixed to the bottom of the material cylinder 1, with its output end penetrating the material cylinder 1 and fixed to the bottom of the slide plate 80. A fixing frame 82 is fixed to the bottom of the slide plate 80, and a motor 83 is fixed to the surface of the fixing frame 82. A gear 84 is passed through and fixed to the output shaft of the motor 83, and is rotatably connected to the bottom of the slide plate 80. A second gear 87 is rotatably connected to the bottom of the slide plate 80. A short rod 86 is provided on the surface of the second gear 87, penetrating the second gear 87 and fixedly connected to it. The end of the short rod 86 away from the second gear 87 penetrates the slide plate 80 and is rotatably connected to it. A stirring plate 88 is fixed to the end of the short rod 86 away from the second gear 87, with its bottom fitting against the top of the slide plate 80. A rack 85 is slidably connected to the bottom of the slide plate 80. The rack 85 engages, and gear 84 has four teeth on its surface, arranged in two groups, arranged in a circular array around the center of gear 84. Gear 87 has half of the teeth on its surface. When motor 83 is turned on, gear 84 rotates continuously. When gear 84 engages with gear 87, gear 87 rotates forward, and rack 85 moves simultaneously. When gear 84 is not engaged with gear 87, it engages with rack 85, which drives rack 85 to move in the opposite direction. At the same time, rack 85 drives gear 87 to rotate in the opposite direction. Thus, when motor 83 is working continuously, gear 87 continuously reciprocates. This reciprocates the stirring plate 88 via short rod 86, preventing material from accumulating in one place and improving the uniformity of material in the material cylinder 1. This prevents material accumulation from affecting subsequent pre-compression processing. When cylinder 81 is activated, it extends, causing slide plate 80 to move upward, thus ejecting the packaged material for easy handling.

[0027] The linkage component 9 includes a fixed column 90, which is fixed to the surface of the rack 85. A groove 91 is formed on the surface of the fixed column 90. A movable column 92 is slidably connected to the inner wall of the groove 91. A spring 93 is fixed to the surface of the movable column 92. The end of the spring 93 away from the movable column 92 is fixed to the inner wall of the groove 91. A short column 94 is fixed to the bottom of the slide plate 80. The ends of the movable column 92 and the short column 94 that are close to each other are both set to be arc-shaped. When the rack 85 reciprocates, the fixed column 90 moves. When the surface of the movable column 92 abuts against the surface of the short column 94, the movable column 92 moves into the groove 91, and the spring 93 is compressed. When the movable column 92 is offset from the surface of the short column 94, the spring 93 is released, causing the movable column 92 to return to its original position. When the rack 85 continues to move, the movable column 92 continues to abut and impact against the surface of the short column 94, causing the slide plate 80 to vibrate, further improving the uniformity of material spreading and facilitating subsequent pre-pressing processing.

[0028] A connecting frame 5 is fixed to the surface of the electric slide rail 4. A cylinder 6 is fixed to the top of the connecting frame 5. The output end of the cylinder 6 passes through the connecting frame 5, and a pressure plate 7 is fixed to the bottom of the output end of the cylinder 6. A stabilizing rod 10 is fixed to the top of the pressure plate 7. The top of the stabilizing rod 10 passes through the connecting frame 5, and the stabilizing rod 10 is slidably connected to the connecting frame 5. When the cylinder 6 is opened, the pressure plate 7 moves down to press the material. The stabilizing rod 10 stabilizes the pressing work of the pressure plate 7, so that the material can be pre-pressed for easy packaging.

[0029] In use, material is fed into the feed cylinder 1, and motor 83 is turned on simultaneously, which drives gear 1 84 to rotate continuously. When gear 1 84 meshes with gear 2 87, it drives gear 2 87 to rotate forward, and rack 85 moves simultaneously. When gear 1 84 is not meshed with gear 2 87, it meshes with rack 85, which drives rack 85 to move in the opposite direction, and rack 85 drives gear 2 87 to rotate in the reverse direction. Thus, while motor 83 is working continuously, gear 2 87 continuously reciprocates, driving the stirring plate 88 to reciprocate through short rod 86. This prevents material from piling up in one place and improves the uniformity of material in the feed cylinder 1 when personnel are continuously feeding. At the same time, the reciprocating motion of rack 85 synchronously drives the fixed column 90 to move, and the movable column 92 moves synchronously. When the surface of movable column 92 abuts the surface of short column 94... When the movable column 92 moves into the slide groove 91, the spring 93 is compressed. When the movable column 92 is offset from the surface of the short column 94, the spring 93 is released, causing the movable column 92 to reset. As the rack 85 continues to move, the movable column 92 continuously contacts and impacts the surface of the short column 94, causing the slide plate 80 to vibrate, further improving the uniformity of the material spreading and facilitating subsequent pre-compression processing. When the feeding is completed, the cylinder 6 is activated, causing the pressure plate 7 to move down to compress the material. The pressure plate 7 is stabilized by the stabilizing rod 10, which allows the material to be pre-compressed for easy packaging. When the material needs to be removed, the electric slide rail 4 is controlled, causing the base plate 3 to move away from the support leg 2 and the material cylinder 1 away from the connecting frame 5. At this time, the cylinder 81 can be activated to extend, causing the slide plate 80 to move up, which can push out the packaged material for easy material removal.

[0030] 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.
