Description

Technical Field

[0001] This utility model relates to the technical field of skin grafting machines, and in particular to a horizontal slicing machine skin grafting machine. Background Technology

[0002] With the widespread application of horizontal planers in the timber industry, traditional planers are mainly used to cut natural solid wood. The cut timber squares are small in size, requiring no veneer joining equipment. The veneer produced by the planers has a low discharge height, allowing for manual veneer joining and stacking. However, with the development of the timber industry, large-sized engineered wood squares require new horizontal planers. These larger squares also have larger veneer sizes, typically 1.2m x 2.44m and less than 1mm thick. During joining, it's crucial to maintain the integrity of the veneer and prevent breakage. However, the pressure frame of new horizontal planers is relatively high, making the veneer fragile, and manual joining is not feasible. Therefore, a veneer joining machine is urgently needed to solve this problem of joining veneers in horizontal planers. Utility Model Content

[0020] The purpose of this utility model is to provide a horizontal planer bark splicing machine to solve the problems existing in the prior art, making the bark splicing operation of the horizontal planer convenient and ensuring that the veneer does not break.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 like Figures 1 to 3As shown, this embodiment provides a horizontal veneer splicing machine, including a first conveyor group and a second conveyor group. One end of the first conveyor group is movably connected to the crossbeam 1 of the horizontal veneer frame of the horizontal veneer, and the other end is slidably mounted on the frame 5 of the second conveyor group. The first conveyor group has several first conveyor belts 2, and the second conveyor group has several second conveyor belts 3, with the first conveyor belts 2 and 3 spaced apart. The first conveyor belts 2 are used to receive the veneer produced by the horizontal veneer, and the second conveyor belts 3 are used to receive the veneer transported by the first conveyor belts 2. The end of the second conveyor belts 3 is manually spliced. In this embodiment, the transport direction of the conveyor belts is considered longitudinal, and the direction perpendicular to the transport direction is considered transverse. By using a method of cross-operation of the two conveyor groups and utilizing the flexibility of the conveyor belts, the problem of manually splicing the veneer after it has been cut by the horizontal veneer is effectively solved.

[0023] As an optional solution, in this embodiment, the first conveyor unit includes a rectangular frame 4 and a first conveyor belt 2. One end of the rectangular frame 4 is hinged to the crossbeam 1 of the ruler holder via a pin, and the other end is slidably mounted on the frame 5 of the second conveyor unit via rollers 8. At least two first conveyor belts 2 are equally spaced and parallel along the length of the rectangular frame 4. The first conveyor belts 2 are connected to a drive motor 12 via a sprocket transmission mechanism. The transport direction of the first conveyor belts 2 faces the end of the second conveyor unit, and the end of the first conveyor belts 2 is located below the second conveyor belt 3. The rectangular frame 4 of the second conveyor unit is horizontally positioned. In this embodiment, the transport direction of the conveyor belts is taken as the length direction of the rectangular frame 4. A pair of hooks 16 are symmetrically arranged on the side wall of the rectangular frame 4. The hooks 16 have semi-circular grooves and are hung on the pins of the crossbeam 1 of the ruler holder via the semi-circular grooves. This facilitates operation and allows the first conveyor belts 2 to slide directionally under the drive of the crossbeam 1 of the ruler holder, avoiding motion interference and jamming.

[0024] As an optional solution, in this embodiment, the frame 5 of the second conveyor unit is lower than the crossbeam 1 of the pressure frame of the horizontal planer. The rectangular frame 4 is inclined downwards. A pair of inclined guide rails 7 are symmetrically arranged on the frame 5. A pair of rollers 8 are symmetrically arranged at the ends of the rectangular frame 4. The rollers 8 and the guide rails 7 are arranged in a one-to-one correspondence and match each other, so that the first conveyor unit slides along the guide rails 7. The angle between the guide rails 7 and the horizontal plane is 3°-10°. Since the blade holder track of the horizontal planer is inclined at about 6° to the horizontal plane, the angle between the guide rails 7 and the horizontal plane is preferably 6° in this embodiment to ensure the smoothness of the reciprocating operation of the first conveyor unit. The sprocket drive mechanism is located below the second conveyor belt 3.

[0025] As an optional solution, in this embodiment, the second conveyor unit includes a frame 5 and a second conveyor belt 3. The frame 5 includes a rectangular frame 4 and a support frame 6. The support frame 6 is provided at the bottom of the rectangular frame 4. At least two second conveyor belts 3 are arranged parallel to each other at equal intervals along the length direction on the rectangular frame 4. The second conveyor belts 3 are connected to a drive motor 12 through a sprocket transmission mechanism. One end of the second conveyor belt 3 is located below the first conveyor unit. The transport direction of the second conveyor belt 3 is set at an obtuse angle or a straight angle with the transport direction of the first conveyor belt 2. The height and angle of the second conveyor belt 3 can be appropriately selected according to the height at which the operator picks up the goods.

[0026] As an optional solution, in this embodiment, the rectangular frame 4 of the second conveyor unit is horizontally arranged, and the support frame 6 is provided with the guide rail 7 for the sliding of the first conveyor unit. The sprocket drive mechanism is located below the first conveyor belt 2, which facilitates installation and avoids interference or collision with the movement of the ruler frame beam 1.

[0027] As an optional solution, in this embodiment, a guide rail height adjustment assembly is provided at the inner end of the rectangular frame 4. The guide rail height adjustment assembly includes a height adjustment bolt 10 and a locking nut 11. One end of the guide rail 7 is hinged to the vertical rod of the support frame 6 via a bearing with a seat, and the other end overlaps the horizontal frame of the rectangular frame 4. A support base 9 is provided at the bottom of the guide rail 7. The height adjustment bolt 10 passes through the vertical frame of the rectangular frame 4, and a locking nut 11 is provided on the height adjustment bolt 10. The locking nut 11 is located on the upper side of the vertical frame, and the top of the height adjustment bolt 10 abuts against the bottom of the support base 9. In this embodiment, by adjusting the height of the height adjustment bolt 10 extending beyond the locking nut 11, a slight adjustment of the swing angle of the guide rail 7 can be achieved.

[0028] As an optional solution, in this embodiment, both the first conveyor belt 2 and the second conveyor belt 3 include pulleys and conveyor belts. The pulleys are protruding and rotatably mounted on the two transverse frames of the rectangular frame 4. The conveyor belts are wound around the pulleys, and the rectangular frame 4 passes through the central cavity of each conveyor belt. The entire process of splicing the wood veneer involves only flexible contact with the belts, without any hard contact, which can avoid damage to the wood veneer. The pulleys are made of materials such as nylon, polyoxymethylene, or metal, which are sturdy and durable.

[0029] As an optional solution, in this embodiment, the sprocket drive mechanism includes a drive shaft 14, sprockets 15, and a chain. A reducer 13 is provided between the sprocket drive mechanism and the drive motor 12. The reducer 13 is connected to the drive shaft 14. Each pulley shaft of the first conveyor belt 2 or the second conveyor belt 3 is connected to a sprocket 15. The drive shaft 14 is provided with several sprockets 15 corresponding to the sprockets 15 on the pulley shaft, forming several sprocket groups. The sprocket groups are connected by chain drive. In this embodiment, one drive motor 12 is connected to multiple pulleys, which can drive multiple sets of conveyor belts to run synchronously, ensuring that the transport speed of the conveyor belt containing the veneer is the same and avoiding damage to the veneer caused by pulling.

[0030] As an optional solution, in this embodiment, the length of the first conveyor belt 2 and the second conveyor belt 3 is at least 1m and the width is at least 8cm. The spacing between adjacent first conveyor belts 2 and adjacent second conveyor belts 3 is at least the width of one conveyor belt, which facilitates the normal operation of adjacent conveyor belts. However, the spacing cannot be too large, and must be at least less than the width of the veneer to prevent the veneer from falling during transportation. The material of the conveyor belt includes rubber, polyvinyl chloride or polyurethane, which is soft and elastic and does not easily damage the veneer.

[0031] As an optional solution, in this embodiment, the second conveyor belt 3 can slide at least 0.5m relative to the first conveyor belt 2, so that the veneer can be smoothly transferred from the first conveyor belt 2 to the second conveyor belt 3 for transport; the width of the first conveyor group and the second conveyor group are both greater than the width of the veneer; the height of the second conveyor group is no more than 1m, preferably close to the height of the operator's hand, so that the operator can easily remove the veneer.

[0032] During the veneer cutting process of a horizontal planer, the veneer outlet moves with the pressure frame. Large veneers are fragile and large in size, making it difficult to collect them without a veneer-joining device. This embodiment solves the problem of collecting veneers after they have been cut from large timbers using a horizontal planer. The pressure frame of the horizontal planer is hinged to a movable first conveyor unit, which reciprocates. After the veneer is cut, the first conveyor belt 2 and the second conveyor belt 3 are installed and run in a cross configuration. The veneer can be seamlessly transported via the inclined conveyor belt on the movable conveyor frame to the fixed horizontal conveyor belt of the second conveyor unit, avoiding damage to the veneer. The height of the second conveyor unit also facilitates subsequent manual collection and stacking.

[0033] Example 2 This embodiment provides a horizontal peeling machine and a skin-jointing machine. Unlike the first embodiment, the rectangular frame 4 of the second conveyor unit is inclined downward or slightly inclined upward to facilitate unloading. The transport direction of the second conveyor belt 3 is set at an obtuse angle or a straight angle with the transport direction of the first conveyor belt 2.
