Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of material processing, and particularly relates to a variable-diameter strip bundle cylinder for gathering bamboo strips scattered at the front end in bamboo cutting, and a bamboo breaking device comprising the variable-diameter strip bundle cylinder. BACKGROUND

[0002] The bamboo breaking device is a mechanical device specially used for uniformly cutting a bamboo cylinder into several equal parts along the axial direction of the bamboo cylinder. The device comprises core components such as a clamping assembly, a bamboo cutting tool and a variable-diameter strip bundle cylinder. Through the synergistic effect of the above three core components, the bamboo cylinder can be stably fixed, accurately cut and effectively gathered, thereby providing great convenience for subsequent processing.

[0003] During use of the bamboo breaking device, the clamping assembly at the front end of the production line is used to stably fix the bamboo cylinder, so that the bamboo cylinder can be aligned with the bamboo cutting tool and will not deviate during processing. Then, the bamboo cylinder is pushed towards the bamboo cutting tool at a constant speed, and the bamboo cutting tool cuts the bamboo cylinder along the axial direction of the bamboo cylinder. Since the front end of the bamboo cylinder after cutting will be in a scattered state, the bamboo breaking device is usually equipped with a variable-diameter strip bundle cylinder to effectively guide the bamboo strips into the next processing process. The variable-diameter strip bundle cylinder can gather and guide the bamboo strips scattered at the front end of the bamboo cylinder, so that the subsequent processing can be smoothly performed.

[0004] At present, the variable-diameter strip bundle cylinder usually comprises a plurality of groups of blocking pieces arranged around the through hole of the bamboo strip, and each group of blocking pieces is provided with an independent air cylinder. The air cylinders adjust the positions of the blocking pieces through the extension and retraction actions, so as to change the size of the through hole and effectively gather the scattered bamboo strips. However, this structure has very high requirements for the synchronization and accuracy of the air cylinders. In actual application, due to the difficulty in ensuring that all air cylinders move completely synchronously, the gathering effect is often poor, such as the bamboo strips not being closely attached or being misaligned, which not only affects the work efficiency, but also reduces the quality of the final product. CONTENT OF THE INVENTION

[0005] To solve the above technical problems, the application provides a variable-diameter strip bundle cylinder, which is implemented by the following technical solutions:

[0006] A variable-diameter bundle tube comprises: a gathering assembly comprising a mounting plate and a plurality of sets of gathering fins hinged to one side of the mounting plate, the free ends of the plurality of sets of gathering fins enclosing a through hole; the gathering fins comprise an inner gathering fin hinged to the mounting plate, and a fitting gathering fin hinged to the inner gathering fin and abutting the outer surface of the inner gathering fin of an adjacent gathering fin; a power assembly comprising an annular transmission member coaxially arranged with the through hole, a driving member for driving the annular transmission member to rotate around the central axis thereof, and a plurality of sets of connecting members arranged at the free ends of the fitting gathering fins and the annular transmission member respectively; the connecting members are uniformly distributed on the annular transmission member.

[0007] Preferably, the inner wall of the fitting gathering fin and the outer surface of the inner gathering fin comprise corresponding fitting surfaces.

[0008] Preferably, a control portion for limiting the maximum diameter of the through hole is formed at the hinged position of the mounting plate and the inner gathering fin.

[0009] Preferably, a notch is arranged on the mounting plate; the control portion comprises a clamping surface arranged on the notch, and a limiting surface arranged on the hinge between the mounting plate and the gathering fin and corresponding to the clamping surface.

[0010] Preferably, the connecting members are arranged in parallel with the annular transmission member; the fitting gathering fin further comprises a coordination control for mounting the connecting members, and the coordination control comprises a short shaft penetrating the connecting members.

[0011] Preferably, a holding surface is arranged on the short shaft close to one end of the fitting gathering fin; when the diameter of the through hole is maximum, one side of the connecting member is in contact with the holding surface.

[0012] Preferably, a limiting surface is arranged on the short shaft away from one end of the fitting gathering fin; when the diameter of the through hole is minimum, the other side of the connecting member is in contact with the limiting surface.

[0013] A bamboo breaking device, characterized in that it comprises any one of the variable-diameter bundle tubes described above.

[0014] Compared with the prior art, the present application has the following beneficial effects:

[0015] The present application drives the annular transmission member to rotate uniformly by the driving member, and uses the connecting members uniformly distributed on the annular transmission member as an intermediate medium; under the driving of the connecting members, the plurality of sets of gathering fins have high consistency in the action of gathering, so that the bamboo pieces can be closely fitted, and the gathering effect is good. This method fundamentally solves the problem of low synchronization and difficulty in ensuring the consistency of the action of all gathering fins when each set of gathering fins is respectively configured with an independent cylinder in the prior art.

[0016] The application sets the fitting pieces on the cohesive pieces, and the connection between the fitting pieces and the connecting members can drive the cohesive pieces to close inward or outward. The application sets the abutting relationship between the fitting pieces and the adjacent cohesive pieces. During the shrinking and closing process of the variable-diameter bundle tube, each cohesive piece can not only be pulled by the fitting pieces in the same group, but also be resisted by the adjacent fitting pieces. Therefore, the bamboo pieces can be bound more evenly, and the closing process is more stable.

[0017] The application sets the fitting surface between the inner wall of the fitting pieces and the outer surface of the cohesive pieces, which can increase the contact area between the fitting pieces and the cohesive pieces in the two adjacent pieces. During the shrinking and closing process of the variable-diameter bundle tube, the resistance of the fitting pieces to the cohesive pieces is greater, so the overall stability of the equipment is higher.

[0018] The application sets the control part at the hinged position of the mounting plate and the cohesive pieces. In the non-working state, for example, in the case of not using the cylinder, the unnecessary direct collision and friction between the pieces and the ring-shaped transmission member can be avoided, the component damage or failure caused by collision can be prevented, and the long-term use stability and safety of the power assembly are ensured.

[0019] The application sets the connecting member parallel to the ring-shaped transmission member, and the short shaft has a holding surface near one end of the fitting pieces. When the diameter of the through hole is the largest, the connecting member can be connected with the holding surface, and can cooperate with the control part to limit the maximum extent of the free end of the fitting pieces at both ends of the fitting pieces. The safety of the equipment is higher.

[0020] The application sets the connecting member parallel to the ring-shaped transmission member, and the short shaft has a holding surface near one end of the fitting pieces. When the diameter of the through hole is the largest, the connecting member can be connected with the holding surface, and can cooperate with the control part to limit the maximum extent of the free end of the fitting pieces at both ends of the fitting pieces.

DETAILED DESCRIPTION

[0028] The present application will be further described below in conjunction with the accompanying drawings and specific examples. Those skilled in the art will be able to implement the present application based on these descriptions. In addition, the examples of the present application involved in the following description are generally only a part of the embodiments of the present application, not all the embodiments. Therefore, based on the examples in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present application.

[0029] Example 1

[0030] The present embodiment discloses a variable-diameter bamboo strip cylinder, which comprises:

[0031] The gathering assembly 100 comprises a mounting plate 110 and a plurality of gathering pieces 120 hinged on one side thereof. The mounting plate 110 is provided with a hole in the middle for the bamboo strips to pass through, and the plurality of gathering pieces 120 are designed around the hole of the mounting plate 110. The free ends of the plurality of gathering pieces 120 are enclosed to form a through hole 130. Therefore, in the use process, the bamboo strips pass through the hole of the mounting plate 110 and the through hole 130 in turn. Of course, in the present application, the two can be regarded as the same through hole 130.

[0032] The gathering piece 120 comprises an inner gathering piece 121 hinged with the mounting plate 110, and a fitting gathering piece 122 hinged with one side edge of the inner gathering piece 121, and the inner wall of the fitting gathering piece 122 is in abutment with the outer wall of the inner gathering piece 121 of the adjacent gathering piece 120. This means that, in the folding process of the variable-diameter bamboo strip cylinder, each inner gathering piece 121 can not only be subjected to the pulling force of its own fitting gathering piece 122, but also be subjected to the abutment force of the adjacent fitting gathering piece 122, so that the bamboo strips can be more evenly bound, and the folding process is more stable.

[0033] Further, in order to increase the contact area between the fitting flaps and the cohesive flaps in the two adjacent flaps, and to increase the resistance of the fitting flaps to the cohesive flaps during the shrinking and folding of the variable-diameter bundle tube, the inner wall of the fitting flaps 122 and the outer surface of the cohesive flaps 121 are provided with corresponding fitting surfaces.

[0034] The power assembly 200 includes an annular transmission member 210 coaxially arranged with the through hole 130, a driving member 220 for driving the annular transmission member 210 to rotate around the central axis, and a plurality of sets of connecting members 230 arranged on the free ends of the fitting flaps 122 and the annular transmission member 210 respectively. The connecting members 230 are uniformly distributed on the annular transmission member 210. By driving the annular transmission member 210 to rotate uniformly by the driving member 220, and by using the connecting members 230 uniformly distributed on the annular transmission member 210 as an intermediate medium, the plurality of sets of flaps 120 are driven by the connecting members 230 to fold in a high consistency, so that the bamboo chips can be closely fitted, and the folding effect is good. This method fundamentally solves the problem of low synchronization and low consistency of the action of all flaps in the prior art when each set of flaps 120 is respectively provided with an independent cylinder.

[0035] In order to ensure that the equipment is in a non-working state, for example, in the case of not starting the driving member 220, avoid unnecessary direct collision and friction between the flaps 120 and the annular transmission member 210, prevent component damage or malfunction caused by collision, and ensure the long-term use stability and safety of the power assembly 200, in the embodiment, a control part 140 for limiting the maximum diameter of the through hole is formed at the hinged position of the mounting plate 110 and the cohesive flaps 121. The mounting plate 110 is provided with a slot 111; the control part 140 includes a clamping surface 141 arranged on the slot 111, and a limiting surface 142 arranged on the hinge 150 between the mounting plate 110 and the flaps 120 and corresponding to the clamping surface 141.

[0036] The embodiment also discloses a use process of the variable-diameter bundle tube: starting the driving member 220 to drive the annular transmission member 210 to rotate uniformly around the central axis; the connecting members 230 are driven by the annular transmission member 210 to pull the flaps 120 to open, thereby increasing the diameter of the through hole 130 and facilitating the bamboo chips to pass through; then, the driving member 220 is started to drive the annular transmission member 210 to rotate reversely around the central axis; the connecting members 230 are driven by the annular transmission member 210 to push the cohesive flaps 121 to fold inward, thereby reducing the diameter of the through hole 130, and realizing the folding of the bamboo chips.
