Description

Technical Field

[0001] The utility model relates to the field of bamboo product production equipment, in particular to a bamboo slice conveying and clamping device. Background Art

[0002] In the process of conveying bamboo pieces, because bamboo pieces are slender and often bend and warp, the vibration of the conveying equipment itself often causes the bamboo pieces to shift or even turn over naturally, affecting the subsequent processing of the bamboo pieces. For example: after taking a photo to confirm the front and back directions of the bamboo pieces being conveyed, they are then conveyed to the bamboo piece clamping and turning mechanism, where they are automatically turned over by the bamboo piece clamping and turning mechanism, so that the front and back directions of each bamboo piece remain consistent, which is convenient for subsequent fine processing. However, after taking the photo, the bamboo pieces turn over naturally, or abnormally, which will affect the consistency of the front and back directions of the bamboo pieces, and thus affect the subsequent fine processing. Utility Model Content

[0003] The utility model aims to provide a bamboo chip conveying and clamping device, which can prevent the bamboo chips from shifting during the conveying process and from turning over abnormally due to machine vibration.

[0004] The technical solution to achieve the purpose of the utility model is: a bamboo chip conveying and clamping device, comprising a frame and a conveyor belt installed inside the frame and capable of conveying up and down; a plurality of lateral supports are arranged at intervals on the conveyor belt along its conveying direction, for supporting the bamboo chips and preventing them from falling;

[0005] At least one of the two lateral sides of each lateral support is provided with a clamping mechanism;

[0006] The clamping mechanism includes a swinging mandrel located on the side of the transversely supported conveyor belt, a pressing plate sleeved on the swinging mandrel and capable of swinging with the swinging mandrel as the central axis, and a resisting plate installed on the frame;

[0007] The swing mandrel is transversely mounted on the conveyor belt;

[0008] The pressing plate is connected to an extension arm which is at a certain angle thereto;

[0009] The contact plate and the transverse support are arranged on both sides of the swinging core shaft, the pressing plate and the transverse support are located on the same side, the extension arm and the contact plate are located on the same side, the plate surface of the contact plate facing the swinging core shaft is its contact surface, and the contact surface is parallel to the conveyor belt; the distance from the swinging core shaft to the contact surface is smaller than the distance from the swinging core shaft to the front end of the extension arm; the contact plate is located on the moving path of the extension arm, and is used to block the moving extension arm so that the moving extension arm and the pressing plate first swing in the direction close to the transverse support under the blocking action of the top surface of the contact plate, and then slide forward along the contact surface; during the process of the extension arm and the pressing plate sliding forward along the contact surface, the pressing plate is always pressed against the bamboo piece located on the transverse support.

[0010] When the extension arm of the bamboo chip conveying and clamping device of the present invention slides forward along the abutment surface, the front end of the extension arm always slides close to the abutment surface. At the same time, the pressing plate always presses against the bamboo chip located on the lateral support to clamp the bamboo chip, thereby preventing the bamboo chip from moving (for example, tilting sideways) or naturally turning over (belonging to "abnormal turning over") due to machine vibration, thereby ensuring smooth conveying of the bamboo chip.

[0011] Furthermore, the included angle α between the extension arm and the pressing plate is ≥90°.

[0012] Furthermore, the clamping mechanism also includes a torsion spring located on the conveyor belt side of the transverse support; the torsion spring is arranged in parallel with the swinging mandrel, one axial end of the torsion spring is fixedly connected to the conveyor belt, and the other axial end of the torsion spring is fixed to the press plate and can drive the press plate to swing in a direction away from the transverse support with the swinging mandrel as the center axis, and the torsion spring is always in a stretched state during the process of the extension arm sliding forward along the contact surface. Therefore, when the resistance of the contact plate is lost, the press plate can swing in the opposite direction with the swinging mandrel as the center axis (i.e., swing in a direction away from the transverse support) under the action of the restoring force of the torsion spring, so that the press plate leaves the bamboo pieces on the transverse support, providing an opportunity for processing the bamboo pieces. Furthermore, the conveyor belt transports downward, and a loading station is provided at the top of the moving path of the lateral support. The upper edge of the resistance plate is located below the loading station. At the loading station, the pressing plate swings in a direction away from the lateral support under the action of the restoring force of the torsion spring until it remains in an upright state, so that the bamboo strips can be lifted to a high place by the existing lifting equipment, and automatically dropped from top to bottom onto the lateral support at the loading station to realize automatic loading of the conveyor belt.

[0013] Furthermore, a bamboo flipping station is provided on the moving path of the lateral support; the contact plate is disconnected for a distance at the bamboo flipping station to release the extension arm so that the extension arm and the press plate lose the obstruction of the contact plate and swing away from the lateral support and open. When the extension arm is driven by the conveyor belt to move through the bamboo flipping station, the extension arm is released due to the loss of the obstruction of the contact plate, and the press plate swings away from the lateral support axially with the swing core shaft as the center under the action of the restoring force of the torsion spring and opens, and the press plate leaves the bamboo piece, so as to actively flip the bamboo piece according to actual needs. By actively flipping the bamboo piece at the bamboo flipping station, it is beneficial to achieve the consistency of the front and back directions of each bamboo piece.

[0014] Furthermore, a bamboo chip pushing and discharging station is provided on the moving path of the lateral support; the contact plate is disconnected for a distance at the bamboo chip pushing and discharging station to release the extension arm so that the extension arm and the pressing plate lose the obstruction of the contact plate and swing away from the lateral support and open, and the pressing plate leaves the bamboo chip, making it easier to push and discharge the bamboo chip.

[0015] Furthermore, the transverse support is composed of two support blocks arranged at a transverse interval. When working, the bamboo strip transverse support is mounted on the two support blocks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The specific implementation of the bamboo chip conveying and clamping device of the utility model is described in detail below in conjunction with the accompanying drawings:

[0022] Combination Figure 1 to Figure 5A bamboo chip conveying and clamping device comprises a frame 10 and a conveyor belt 20 installed inside the frame 10 and capable of conveying up and down; a plurality of transverse supports 30 are arranged at intervals on the conveyor belt 20 along its conveying direction, for supporting the bamboo chip 1 to prevent it from falling;

[0023] At least one of the two lateral sides of each lateral support 30 is provided with a clamping mechanism 40;

[0024] The clamping mechanism 40 includes a swinging mandrel 41 located on the conveyor belt 20 side of the lateral support 30, a pressing plate 42 sleeved on the swinging mandrel 41 and capable of swinging with the swinging mandrel 41 as the central axis, and a resisting plate 43 installed on the frame 10;

[0025] The swing mandrel 41 is transversely mounted on the conveyor belt 20;

[0026] The pressing plate 42 is connected to an extension arm 421 which is at a certain angle thereto;

[0027] The abutment plate 43 and the transverse support 30 are arranged on both sides of the swing mandrel 41, the pressing plate 42 and the transverse support 30 are located on the same side, the extension arm 421 and the abutment plate 43 are located on the same side, the plate surface of the abutment plate 43 facing the swing mandrel 41 is its abutment surface 431, and the abutment surface 431 is parallel to the conveyor belt 20; the distance L from the swing mandrel 41 to the abutment surface 431 is less than the distance L from the swing mandrel 41 to the front end of the extension arm 421. Distance L'; the contact plate 43 is located on the moving path of the extension arm 421, and is used to block the moving extension arm 421 so that the moving extension arm 421 and the pressing plate 42 first swing toward the direction close to the lateral support 30 under the blocking effect of the top surface of the contact plate 43, and then slide forward along the contact surface 431; during the process of the extension arm 421 and the pressing plate 42 sliding forward along the contact surface 431, the pressing plate 42 is always pressed against the bamboo piece 1 located on the lateral support 30.

[0028] During the operation of the conveyor belt 20, the pressing plate 42 and the extension arm 421 are driven by the conveyor belt 20 to move. When passing through the abutment plate 43, Figure 3 and Figure 5As shown, the contact plate 43 can block the moving extension arm 421 so that the moving extension arm 421 and the pressing plate 42 first swing toward the direction close to the lateral support 30 under the blocking action of the top surface of the contact plate 43, and then slide forward smoothly along the contact surface 431. When the front end of the extension arm 421 abuts against the contact plate 43 and is driven by the conveyor belt 20 to slide forward, the pressing plate 42 swings to the maximum amplitude toward the direction close to the lateral support 30. At this time, the pressing plate 42 just presses against the bamboo piece located on the lateral support 30. In the process of sliding forward smoothly, the front end of the extension arm 421 always slides close to the contact surface 431, and the pressing plate 42 always presses against the bamboo piece located on the lateral support 30, thereby pressing the bamboo piece, avoiding the movement of the bamboo piece (for example, tilting sideways) or natural flipping (belonging to "abnormal flipping") caused by machine vibration, and ensuring the smooth transportation of the bamboo piece.

[0029] The central axis of the torsion spring 44 and the swing core shaft 41 may share a common axis (such as Figure 4 As shown), it can also be two independent and parallel axes.

[0030] Further, such as Figure 5 As shown, the included angle α between the extension arm 421 and the pressing plate 42 is ≥90°.

[0031] Further, combined with Figure 2 , Figure 4 and Figure 5 , the clamping mechanism 40 also includes a torsion spring 44 located on the conveyor belt 20 side of the transverse support 30; the torsion spring 44 is arranged parallel to the swinging core shaft 41, one axial end of the torsion spring 44 is fixedly connected to the conveyor belt 20, and the other axial end of the torsion spring 44 is fixed to the pressing plate 42 and can drive the pressing plate 42 to swing in a direction away from the transverse support 30 with the swinging core shaft 41 as the center axis, and the torsion spring 44 is always in a stretched state during the process of the extension arm 421 sliding forward along the contact surface 431. Therefore, when the resistance of the contact plate 43 is lost, the pressing plate 42 can swing in the opposite direction (i.e., swing in a direction away from the transverse support 30) with the swinging core shaft 41 as the center axis under the action of the restoring force of the torsion spring 44, so that the pressing plate 42 leaves the bamboo chips on the transverse support 30, providing an opportunity for processing the bamboo chips. Furthermore, as Figure 5 As shown, the conveyor belt 20 transports downward, and a loading station 100 is provided at the top of the moving path of the lateral support 30, and the upper edge of the contact plate 43 is located below the loading station 100. At the loading station, the pressing plate 42 swings in a direction away from the lateral support 30 under the restoring force of the torsion spring 44 until it remains in an upright state, so that the bamboo pieces can be lifted to a high place by the existing lifting equipment, and automatically dropped from top to bottom onto the lateral support 30 at the loading station 100 to realize automatic loading of the conveyor belt 20.

[0032] Further, combined with Figure 1 and Figure 5 , a bamboo flipping station 200 is also provided on the moving path of the lateral support 30; the contact plate 43 is disconnected for a distance at the bamboo flipping station 200, and is used to release the extension arm 421 so that the extension arm 421 and the pressing plate 42 lose the obstruction of the contact plate 43 and swing away from the lateral support 30 and open. When the extension arm 421 is driven by the conveyor belt 20 to move through the bamboo flipping station 200, the extension arm 421 is released due to the loss of the obstruction of the contact plate 43, and the pressing plate 42 will swing away from the lateral support 30 axially with the swing core shaft 41 as the center under the restoring force of the torsion spring 44, and open, and the pressing plate 42 leaves the bamboo piece, so as to actively flip the bamboo piece according to actual needs, and by actively flipping the bamboo piece at the bamboo flipping station 200, it is conducive to achieving the consistency of the front and back directions of each bamboo piece.

[0033] Further, combined with Figure 1 and Figure 5 , a bamboo chip pushing and discharging station 300 is also provided on the moving path of the lateral support 30; the abutment plate 43 is disconnected for a distance at the bamboo chip pushing and discharging station 300, and is used to release the extension arm 421 so that the extension arm 421 and the pressing plate 42 lose the obstruction of the abutment plate 43 and swing away from the lateral support 30 and open, and the pressing plate 42 leaves the bamboo chip, which facilitates the pushing and discharging of the bamboo chip. Since the extension arm 421 is driven by the conveyor belt 20 to move through the bamboo chip pushing and discharging station 300, the swinging working state of the pressing plate 42 and the extension arm 421 is the same as that at the bamboo chip turning station 200, so it is not shown.

[0034] Further, such as Figure 1 As shown, the transverse support 30 is composed of two support blocks arranged at a transverse interval. During operation, the bamboo strip transverse support is mounted on the two support blocks.

[0035] Further, such as Figure 1As shown, the conveyor belt 20 can be composed of two sets of first conveyor chains that are symmetrically arranged at intervals. When the conveyor belt 20 is conveying downward, a lifting and loading mechanism 50 is arranged between the two sets of conveyor chains, and the lifting and loading mechanism 50 includes a lifting conveyor belt 51, and a plurality of lifting transverse supports 52 are arranged at intervals along the conveying direction of the lifting conveyor belt 51 to support the bamboo pieces from falling; the top of the lifting conveyor belt 52 is higher than the conveyor belt 20, and material receiving guide slopes 53 are respectively arranged on both sides of the top of the lifting conveyor belt 52, and the material receiving guide slopes 53 are arranged downwardly in a direction from the top of the lifting conveyor belt 52 to the loading station 100 of the conveyor belt 20. During operation, the bamboo pieces are placed horizontally on the lifting transverse support 52 and driven by the lifting conveyor belt 51 to be transported upward to the top thereof, and the lifting transverse support 52 is gradually turned from the bottom of the bamboo pieces to the top of the bamboo pieces at the top turning point of the lifting conveyor belt 51. The bamboo pieces will naturally fall onto the receiving guide inclined surface 53 due to the loss of the bottom support provided by the lifting transverse support 52, and slide toward the feeding station 100 of the conveyor belt 20 under the guidance of the receiving guide inclined surface 53 and fall onto the transverse support 30 at the feeding station 100, thereby realizing automatic feeding of the conveyor belt 20. Of course, the lifting and feeding mechanism 50 may not be provided in the present invention.

[0036] Furthermore, each of the lateral sides of the lateral support 30 is provided with a clamping mechanism 40. The clamping mechanisms 40 on both sides may adopt the same structure (for example, both use the clamping mechanism 40 described in the embodiment of the utility model), or may adopt two different types of clamping mechanisms (wherein the clamping mechanism on one side adopts the clamping mechanism described in the embodiment of the utility model, and the clamping mechanism on the other side adopts another type of clamping mechanism), so as to achieve complementary advantages of the two clamping mechanisms.

[0037] For ordinary technicians in the technical field to which the utility model belongs, the utility model can make several simple deductions or substitutions without departing from the concept of the utility model, which should be regarded as falling within the protection scope of the utility model.
