[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0025] like Figure 1-3 As shown, a baler lifting door includes a door body 1 and a limit block 6. The door body 1 is a solid metal plate with a thickness of 3-5 cm. Hinge ears 3 extend from both sides of the door body 1 to form a T-shaped structure. Lifting devices 2 are hinged on the two hinge ears 3 respectively to perform lifting after baling is completed. The lifting device 2 can be a winch, an electric hoist, a cylinder, etc.

[0026] The limit block 6 is adapted to the width of the packaging chamber of the packaging machine. The limit block 6 is placed inside the packaging machine. Multiple limit blocks 6 form an extrusion surface, which serves as a force-bearing surface for the packaged object during packaging, and cooperates with the extrusion cylinder to extrude the packaged object.

[0027] A plurality of limit blocks 6 are longitudinally spaced apart and distributed in the packing area of ​​the inner wall of the door body 1. The packing area is opposite to the packing chamber of the packing machine, and a threading groove 7 is formed between two adjacent limit blocks 6. After the object to be packed is squeezed, the lifting door can be lifted upward by inserting the packing rope into the threading groove 7, and the object to be packed can be pushed out of the packing machine by continuing to push the object to be packed through the squeezing cylinder.

[0028] The side walls of the stopper 6 corresponding to both sides of the threading groove 7 are inclined downward away from the door body 1, so that the packing rope can be squeezed out of the threading groove 7 during the lifting work, thereby avoiding cutting the packing rope during the lifting process. The side wall of the stopper 6 corresponding to the lower side of the threading groove 7 is provided with a smooth transition angle corresponding to the shrinkage, and the packing rope can smoothly pass through the smooth transition angle, so that there will be no hard contact between the stopper 6.

[0029] In addition, the inclination of the side wall of the limit block 6 corresponding to the upper side of the threading groove 7 is greater than that of the side wall of the limit block 6 corresponding to the lower side of the threading groove 7, so that the threading groove 7 forms an opening corresponding to the constriction of the packing rope; the threading groove 7 is set to be a constriction, which can maximize the contact area (extrusion surface) with the object to be packaged while ensuring smooth threading, ensuring that the object to be packaged will not invade the threading groove 7 and affect lifting.

[0030] In an optional embodiment, the limit block 6 includes an upper plate 601 and a lower plate 602, both of which are steel plates, wherein the upper plate 601 is an L-shaped bending structure, one end of the upper plate 601 is a fixed end, and the other end is a bending end, wherein the bending portion between the fixed end and the bending end forms a smooth transition angle through a smooth transition bend, the fixed end of the upper plate 601 is welded and fixed to the inner wall of the door body 1, and the bending end of the upper plate 601 is formed by bending to form a lower wall corresponding to the wire threading groove 7, and the end extends downward and is parallel to the door body 1 or slightly inclined to the door body 1.

[0031] The lower plate 602 is a straight plate, one end of which is fixed on the door body 1, and the other end extends to the end of the upper plate 601 and is fixedly connected thereto to form the upper wall of the wire threading groove 7. The upper plate 601 and the lower plate 602 form a cavity with the door body 1. In order to ensure the strength of the limit block 6, a plurality of support plates 603 are provided in any limit block 6, and the support plates 603 are adapted to the cross-section of the inner cavity of the limit block 6.

[0032] In an optional embodiment, end plates are provided on both sides of the limit block 6, and the end plates are steel plates with the same thickness as the upper plate 601 and the lower plate 602. Notches corresponding to the wire threading groove 7 are provided on the end plates, and the side walls on both sides of the notch are adapted to the side walls on both sides of the wire threading groove 7. A smooth inner wall is provided at the end of the notch close to the door body 1 to facilitate the insertion of the packing rope.

[0033] In this embodiment, the bent end of the upper plate 601 is inclined toward the door body 1, thereby forming an inclined extrusion surface. Furthermore, the bent ends of the upper plates 601 of the plurality of limit blocks 6 are located on the same inclined surface. During the actual lifting process, the difficulty of lifting can be reduced. The inclination angle of the inclined surface can be 1-5 degrees, and the side of the corresponding end plate close to the extrusion surface is inclined at the same angle as the extrusion surface, and the two are located on the same inclined surface.

[0034] In an optional embodiment, columns 4 are provided on both sides of the door body 1. The columns 4 can be welded from I-beams or steel plates. The inner side of the columns 4 is provided with a slide groove corresponding to the door body 1 and extending along the longitudinal direction. The lifting device 2 is correspondingly arranged on the outer side of the columns 4. The lifting device 2 is preferably an oil cylinder.

[0035] In this embodiment, the lifting door is arranged at the outlet of the baler through the column 4, and strip holes corresponding to the narrowed ends of the wire threading groove 7 are provided on both sides of the column 4. An end of the strip hole corresponding to the wire threading groove 7 is provided with an expanded section corresponding to the larger end of the wire threading groove 7, extending to one end of the side wall of the baler body close to the lifting door.

[0036] In an optional embodiment, the length of the bent end of the top limit block 6 is extended so that its fixed end is not lower than the upper edge of the packaging chamber of the packaging machine, and the lower plate 602 of the bottom limit block 6 extends horizontally so as to be stably placed at the bottom of the packaging chamber of the packaging machine.

[0037] In an optional embodiment, a baffle 5 is provided on the column 4 and is located on both sides of the end plate. The baffle is used to connect the side walls on both sides of the baler and is fixed by welding between the side walls on both sides of the baler and the column 4. The inner side of the baffle 5 is close to the end plate, and the inner side of the baffle 5 is in the same plane as the inner surface of the side wall of the baler body. The flared section extends to the baffle 5, and the baffle 5 is provided with an arc-shaped notch 8 corresponding to the end of the flared section, so as to facilitate the insertion of the baling rope, and also make way for the baling rope when the baled objects are squeezed out after binding.

[0038] The width of the strip hole is adapted to the diameter of the packing rope, and the two sides of the strip hole are inclined so that the cross section of the strip hole forms a V-shaped structure with the larger section pointing to the packing cavity, thereby preventing the packed items from being damaged when being longitudinally squeezed during the pushing process.

[0039] The width of the expanded section is greater than 2 times the diameter of the packing rope. During the lifting process of the lifting door, the packing rope can make some concessions in the longitudinal direction, thereby further avoiding the packing rope and the threading groove from being squeezed.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
