Description

Technical Field

[0001] The utility model belongs to the technical field of bamboo chip production, in particular to a stacking structure used on a bamboo board sorting machine. Background Art

[0002] In the production of bamboo chips, the sorted bamboo chips need to be bundled and stacked sideways. Different bundles of bamboo chips are bundled together in different numbers, that is, the width of each bundle of bamboo chips is different. Bamboo chips of different colors need to be classified and stacked on the stacking structure.

[0003] Generally, in order to correctly stack the bundled bamboo pieces, a motor with a stroke control is often used to accurately deliver the bamboo pieces to a predetermined position, and a lifting structure is used to further deliver the bamboo pieces to a preset height. Therefore, the prior art generally improves the stroke motor or the lifting structure.

[0004] For example, the Chinese utility model patent with the authorization announcement number CN118439229U and the authorization announcement date 20240806 discloses a flexible stacking device for bundled bamboo pieces, which includes a pneumatic lifting mechanism and an adaptive clamping mechanism, and the lifting end of the pneumatic lifting mechanism is connected to the adaptive clamping mechanism. The pneumatic lifting mechanism includes a first cylinder, a housing, a synchronous belt, a guide wheel, a pressure wheel, a core shaft, a spring box and a scroll spring. The housing is fixed on the piston rod of the first cylinder, the core shaft is installed in the housing, and one end of the core shaft extends outside the housing and is connected to the inner ring of the scroll spring, and the outer ring of the scroll spring is fixed on the spring box.

[0005] The general structural principle and advantages of the stacking device in this utility model patent are as follows: a single-axis cylinder with a simple structure is used to discharge bamboo strips bundled at different height layers with a fixed reciprocating stroke of the cylinder, and it has the function of adaptive height; and a single-axis cylinder with a simple structure is used to realize flexible material collection of bamboo strips of different widths; the guide wheel is tensioned by a volute spring, and the synchronous belt connected to one side of the adaptive clamping mechanism can always remain in a tensioned state, avoiding the problems caused by the spin of the piston rod of the single-axis cylinder.

[0006] However, in actual use, the stacking device still has at least the following shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0007] The device only uses an ordinary bottom plate to support the bamboo pieces. After the bamboo pieces are stacked to a predetermined height under the cyclic operation of the pneumatic lifting mechanism, there is a risk of collapse, which poses a safety hazard.

[0008] Therefore, in summary, there is an urgent need for a stacking structure that can effectively protect the stacked bamboo pieces and prevent them from collapsing. Utility Model Content

The device has sufficient limiting and stabilizing effects on the stacked bamboo slices, and the stacked bamboo slices are not prone to tipping or falling. 2. When transferring the bamboo slices, the friction between the bamboo slices and the device is reduced, protecting the bamboo slices from abrasion.

[0034] The following is only a preferred embodiment of the present utility model, and does not limit the scope of the present utility model.

[0035] Embodiment 1

[0036] As shown in the appendix Figures 1-4 As shown, a stacking structure used in a bamboo board sorting machine includes a bottom plate 11 and support feet 12. It also includes a plurality of support bar units 1 arranged on the bottom plate 11 and distributed in parallel, a vertical bar unit 2 arranged on the bottom plate 11 and located at the side end of the support bar unit 1, and a plurality of roller units 3 with both ends respectively connected to adjacent two support bar units 1 for supporting bamboo slices a.

[0037] In this embodiment, the bottom plate 11 is rectangular in shape, and the support feet 12 are installed at the four corners of the bottom plate 11 to support the bottom plate 11. The support bar units 1 are horizontally distributed, and adjacent two support bar units 1 form a horizontal track for supporting bamboo slices a, that is, the bamboo slices a are conveyed by a motor with a stroke between adjacent two support bar units 1, and the bottom of the bamboo slices a contacts the two support bar units 1. The position of the vertical bar unit 2 matches that of the support bar unit 1. The vertical bar unit 2 is vertically distributed, and adjacent two vertical bar units 2 form a vertical track for limiting the stacking position of bamboo slices a, that is, the ends of all bamboo slices a contact the two vertical bar units 2 and complete stacking under the limitation. The number of the roller units 3 is 2 to 5, and they are installed at a certain interval between the two support bar 1 units. The function is that when transferring the stacked bamboo slices a, the bamboo slices a can be taken out by pulling the bamboo slices a, changing the sliding friction between the original bamboo slices a and the support bar unit 1 into the rolling friction between the bamboo slices a and the roller units 3, which not only saves effort but also reduces the wear degree of the bamboo slices a and ensures the quality of the bamboo slices a.

[0038] This stacking structure is used in cooperation with a motor with a stroke that has the function of conveying bamboo slices a. When in use, the bamboo slices a are conveyed above the two support bar units 1, and the ends of the bamboo slices a are located at the upper ends of the two vertical bar units 2; the motor releases the bamboo slices a, and the bamboo slices a are supported by the two support bar units 1, and the ends are located between the two vertical bar units 2. Repeat the above steps to complete the stacking of the bamboo slices a on one track. It should be noted that the stacking height should not exceed the height of the vertical bar unit 2.

[0039] The support bar unit 1 includes a support bar 101 and an installation groove 102 arranged on the support bar 101 for installing the roller unit 3.

[0040] In this embodiment, the main material of the support bar 101 is metal, and its shape is strip-shaped. Square steel can also be directly used. The installation groove 102 is a groove with an open upper end, and the shape of the groove is rectangular.

[0041] The vertical rod unit 2 includes an installation bar 201 perpendicular to the support bar 101 and connected to all the support bars 101, installation holes 202 provided on the installation bar 201 and corresponding to the positions of the support bars 101 one by one, and vertical rods 203 inserted into the installation holes 202.

[0042] In this embodiment, the main body of the installation bar 201 is metal, and its shape is strip-shaped. Square steel can also be directly used. The length of the installation bar 201 is sufficient to be connected to all the installation bars 201. The number of the installation bars 201 is two, which are distributed at both ends of the support bar 101. The two installation bars 201 and the two outermost support bars 101 are connected to form a frame, thereby improving the structural strength. The main body of the vertical rod 203 is metal, and the height of the vertical rod 203 can have multiple specifications for selection, so as to correspond to the stacking height of the bamboo slices a required in the actual scenario.

[0043] The vertical rod unit 2 further includes adjustment holes 204 provided on the installation bar 201 and located between two adjacent installation holes 202 for installing the vertical rods 203.

[0044] In this embodiment, the adjustment holes 204 can facilitate the adjustment of the distance between two adjacent vertical rods 203, so as to adapt to bamboo slices a with different widths. During use, generally only the position of one vertical rod 203 needs to be adjusted. At this time, the distance between the two vertical rods 203 becomes smaller, which is convenient for limiting and clamping the end of the bamboo slice a. It should be noted at this time that only one side of the main part of the bamboo slice a is supported by the support bar 101 and loses support. In this case, the support strength of the bamboo slice a by the installation bar 201 at the end of the bamboo slice a is still sufficient. Therefore, when facing bamboo slices a with a width smaller than the distance between two installation holes 202, the stacking height needs to be reduced to avoid the risk of irreversible deformation or even fracture in the middle of the bottom bamboo slice a due to excessive pressure.

[0045] The roller unit 3 includes a fixed shaft 301 with its end installed in the installation groove 102, and a roller 302 rotatably arranged on the fixed shaft 301.

[0046] In this embodiment, the upper surface of the roller 302 is flush with or slightly higher than the upper surface of the support bar 101 to ensure that a force can be generated between the bamboo slice a and the roller 302. The rotational connection between the fixed shaft 301 and the roller 302 is prior art and will not be elaborated here.

[0047] The roller shaft unit 3 further includes a vertical section 303 provided at the end of the fixed shaft 301 and matching the groove side wall of the mounting groove 102.

[0048] In this embodiment, the vertical section 303 changes the surface of the fixed shaft 301 in contact with the groove side wall of the mounting groove 102 from an arc surface to a plane that can be closely attached, so that the mounting groove 102 can reversely clamp the fixed shaft 301, avoiding the rotation of the fixed shaft 301 driven by the drum 302 and reducing the wear between the fixed shaft 301 and the mounting groove 102.

[0049] Embodiment 2

[0050] This embodiment optimizes the structure on the basis of Embodiment 1, aiming to reduce the impact force of the bamboo strip a when falling on the support bar unit 1 and the roller shaft unit 3. As shown in the appendix Figures 5-6 The specific structure is as follows:

[0051] The support bar unit 1 further includes two grooves 103 provided on the support bar 101 and located on both sides of the mounting groove 102, two sliders 104 respectively slidably connected in the two grooves 103, two mounting posts 105 respectively provided at the upper ends of the two sliders 104, two elastic components 106 respectively provided in the two grooves 103 and used to support and lift the mounting posts 105, and a support plate 107 with both ends respectively connected to the two mounting posts 105.

[0052] In this embodiment, the number of structures formed by the above components corresponds to the number of roller shaft units 3. The groove 103 is an open-top groove, the shape of the groove is rectangular, and the groove bottom surface is arc-shaped. The cross-section of the slider 104 is circular and matches the arc-shaped groove bottom surface of the groove 103. The mounting post 105 protrudes above the groove 103, the material is metal, and the shape is cylindrical or square-columnar. The elastic component 106 can adopt elements commonly used by those skilled in the art, such as springs, etc., to support and lift the mounting post 105. The support plate 107 is located above the support bar 101 and parallel to the support bar. When there is no pressure on the upper surface of the support plate 107, the mounting post 105 keeps the upper surface of the support plate 107 slightly higher than the upper surface of the drum 302 under the action of the elastic component 106. When in use, the falling bamboo strip a first contacts the support plate 107 and presses down the support plate 107, and the elastic component 106 absorbs most of the impact force. When the subsequent bamboo strip a contacts the upper surface of the drum 302, the impact force on the drum 302 is greatly reduced, which is beneficial to protecting the bamboo strip a and the drum 302. It should be noted that when the gravity of the bamboo strip a is greater than the support force provided by the support plate 107, there is a pressure contact between the bamboo strip a and the drum 302 to ensure the effect of the drum 302.

[0053] The support bar unit 1 further includes a buffer layer 108 disposed on the upper surface of the support plate 107.

[0054] In this embodiment, the material of the buffer layer 108 may be a common material such as rubber, aiming to further improve the buffering effect of the support plate 107 and avoid wear.

[0055] The elastic component 106 includes two side slots 106a disposed at both side ends of the groove 103 and respectively communicating with the groove 103, limit posts 106b disposed at both side ends of the slider 104 and respectively slidably connected to the two side slots 106a, and two jacking springs 106c respectively disposed on the inner bottom surfaces of the two side slots 106a and used for supporting the limit posts 106b.

[0056] In this embodiment, the above structure is an example of the elastic component 106. Among them, the limit posts 106b are parallel to the bottom surface of the side slot 106a, further improving the stability of the vertical movement of the slider 104.

[0057] The elastic component 106 further includes a limit rod 106d disposed in the side slot 106a, an opening 106e disposed on the limit post 106b and used for passing through the limit rod 106d, and a limit block 106f disposed at the upper end of the limit rod 106d.

[0058] In this embodiment, the limit rod 106d is disposed inside the jacking spring 106c and does not contact the jacking spring 106c to ensure that the effect of the jacking spring 106c is not affected. The diameter of the opening 106e is larger than the diameter of the limit rod 106d to avoid sliding friction between the limit rod 106d and the limit post 106b. The diameter of the limit block 106f is larger than the diameter of the opening 106e to avoid the limit post 106b from disengaging upward from the limit rod 106d.

[0059] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various modifications can be made without departing from the purpose of the present invention. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present invention.
