Description

Technical Field

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

[0002] During the conveying process of bamboo strips, due to their slenderness and frequent bending and warping, the vibration of the conveying equipment itself often causes the bamboo strips to shift or even flip over naturally, affecting the subsequent processing of the bamboo strips. For example, after the bamboo strips are transported and photographed to confirm the front and back orientation, they are then transported to the bamboo strip clamping and flipping mechanism, where they are automatically flipped over to ensure that the front and back orientations of each bamboo strip remain consistent, facilitating subsequent fine processing. However, if the bamboo strips naturally flip over after the photograph is taken, the consistency of the front and back orientations of the bamboo strips will be affected, thus affecting the subsequent fine processing. Utility Model Content

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

[0004] The technical solution for achieving the purpose of the utility model is: a bamboo chip conveying and pressing device, comprising a frame and a first conveyor belt installed on the inner side of the frame and capable of conveying up and down; a plurality of first transverse supports are arranged on the first conveyor belt at intervals along its conveying direction, for supporting the bamboo chips to prevent them from falling; at least one of the two transverse sides of each first transverse support is provided with a pressing mechanism, and the pressing mechanism includes a swinging core shaft laterally arranged on the first conveyor belt side of the first transverse support, a pressing plate sleeved on the swinging core shaft and capable of swinging axially close to the first transverse support with the swinging core shaft as the center, and a pressing plate swinging transmission mechanism, and the swinging core shaft is installed on the first conveyor belt.

[0005] The bamboo chip conveying and pressing device of the present invention drives the pressing plate to swing toward the first lateral support through the pressing plate swinging transmission mechanism, so that the pressing plate presses against the bamboo chips located on the first lateral support, pressing the bamboo chips on the first lateral support, thereby preventing the bamboo chips from moving (for example, tilting sideways) or naturally turning over (belonging to "abnormal turning") due to machine vibration during the up and down conveying process, thereby ensuring smooth conveying of the bamboo chips.

[0006] Furthermore, the press plate swing transmission mechanism includes a torsion spring located on the first conveyor belt side of the first transverse support, the torsion spring is arranged parallel to the swing core shaft, 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 axially close to the transverse support with the swing core shaft as the center, so that the press plate is pressed against the bamboo piece located on the first transverse support. Furthermore, a loading station is provided at one end of the moving path of the first transverse support, and the press plate swing transmission mechanism also includes a fixed stopper installed on the frame at the loading station, the swing core shaft is installed on the side wall of the first conveyor belt, the fixed stopper and the press plate are both laterally offset from the first transverse support, and the fixed stopper is located on the moving path of the press plate, for blocking the moving press plate so that the moving press plate swings away from the first transverse support and opens under the blocking action of the fixed stopper. The pressing plate is driven by the first conveyor belt to move. When passing through the fixed stop, it touches the fixed stop and, under the blocking action of the fixed stop, swings away from the first transverse support and opens. At this time, the space between the pressing plate and the corresponding first transverse support becomes larger, and bamboo strips can be loaded at this time. When the pressing plate leaves the loading station and the fixed stop, it can swing axially toward the first transverse support with the swing core axis as the center under the action of the torsion spring restoring force, thereby pressing the bamboo strips on the first transverse support. The pressing force of the pressing plate on the bamboo strips is an elastic force, which provides conditions for actively clamping and turning the bamboo strips during the process of pressing and conveying the bamboo strips, as well as for pushing and unloading the bamboo strips and other processing operations.

[0007] Furthermore, the first conveyor belt is configured to transport bamboo strips downward. The first conveyor belt is composed of two sets of first conveyor chains arranged symmetrically and spaced apart from each other. A lifting and loading mechanism is provided between the two conveyor chains. The lifting and loading mechanism includes a second conveyor belt capable of transporting bamboo strips upward. The second conveyor belt is provided with a plurality of second transverse supports spaced apart along its conveying direction to support the bamboo strips and prevent them from falling. The top of the second conveyor belt is higher than that of the first conveyor belt, and a material receiving guide slope is provided on both sides of the top of the second conveyor belt. The material receiving guide slope is arranged downwardly from the top of the second conveyor belt to the loading station of the first conveyor belt. During operation, bamboo strips are placed horizontally on the second transverse supports and transported upward to the top of the second conveyor belt. At the turning point of the top of the second conveyor belt, the second transverse supports gradually rotate from below the bamboo strips to above the bamboo strips. The bamboo strips, losing the bottom support provided by the second transverse supports, naturally fall onto the material receiving guide slopes. Guided by the material receiving guide slopes, they slide toward the loading station of the first conveyor belt and land on the first transverse supports at the loading station, thereby automatically loading the first conveyor belt.

[0008] The first transverse support is preferably composed of two first support blocks arranged laterally at intervals. During operation, the bamboo strip transverse support is mounted on the two first support blocks.

[0009] Furthermore, a clamping mechanism is correspondingly provided on both lateral sides of each of the first lateral supports. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The preferred embodiment of the bamboo chip conveying and pressing device of the present invention is described in detail below with reference to the accompanying drawings:

[0014] Combine Figures 1 to 3 , a bamboo chip conveying and pressing device, comprising a frame 10 and a first conveyor belt 20 installed on the inner side of the frame 10 and capable of conveying up and down; a plurality of first transverse supports 30 are arranged on the first conveyor belt 20 at intervals along its conveying direction, for supporting the bamboo chips and preventing them from falling; at least one of the two transverse sides of each first transverse support 30 is provided with a pressing mechanism 40, the pressing mechanism 40 comprising a swinging core shaft 41 arranged transversely on the first conveyor belt 20 side of the first transverse support 30, a pressing plate 42 sleeved on the swinging core shaft 41 and capable of swinging axially close to the first transverse support 30 with the swinging core shaft 41 as the center, and a pressing plate swing transmission mechanism 43, the swinging core shaft 41 being installed on the first conveyor belt 20;

[0015] Among them, the pressing plate swing transmission mechanism 43 includes a torsion spring 431 located on the first conveyor belt 20 side of the first transverse support 30, and the torsion spring 431 is arranged parallel to the swing core shaft 41. One axial end of the torsion spring 431 is fixedly connected to the conveyor belt, and the other axial end of the torsion spring 432 is fixed to the pressing plate 42 and can drive the pressing plate 42 to swing axially close to the transverse support direction with the swing core shaft 41 as the center, so that the pressing plate 42 is pressed against the bamboo piece 1 located on the first transverse support 30.

[0016] During operation, the bamboo piece 1 is placed horizontally on the first transverse support 30, and the pressing plate 42 swings axially close to the first transverse support 30 with the swing core shaft 41 as the center under the action of the restoring force of the torsion spring 431, so that the pressing plate 42 presses against the bamboo piece located on the first transverse support 30, pressing the bamboo piece 1 on the first transverse support 30.

[0017] The bamboo chip conveying and pressing device of the present invention cooperates with the first transverse support 30 and the pressing plate 42 to press the bamboo chips on the first transverse support 30, thereby preventing the bamboo chips from moving (for example, tilting sideways) or abnormal flipping caused by machine vibration during the up and down conveying process, thereby ensuring smooth conveying of the bamboo chips.

[0018] Of course, the swing transmission mechanism 43 of the press plate of the present invention can be but not limited to the swing transmission mechanism driven by the torsion spring 431, and can also adopt any existing type of swing transmission mechanism, such as a swing transmission mechanism driven by a cylinder. The central axis of the torsion spring 431 and the swing core shaft 41 can be two independent and parallel axes (such as Figure 2 as shown), or they can share a common axis.

[0019] Further, combined Figures 1 to 3 A loading station 100 is provided at one end of the moving path of the first transverse support 30, and the pressing plate swing transmission mechanism 43 also includes a fixed stopper 432 installed on the frame 10 at the loading station, and the swinging core shaft 41 is installed on the side wall of the first conveyor belt 20, and the fixed stopper 432 and the pressing plate 42 are both laterally staggered with the first transverse support 30, and the fixed stopper 432 is located on the moving path of the pressing plate 42, and is used to block the moving pressing plate 42 so that the moving pressing plate 42 swings away from the first transverse support 30 under the blocking action of the fixed stopper 432 and opens, and then the bamboo piece is placed horizontally on the first transverse support 30 to complete the loading. The pressing plate 42 is driven by the first conveyor belt 20 and moves. When it passes the fixed stop 432, it contacts the fixed stop 432 and swings open, away from the first transverse support 30, under the blocking action of the fixed stop 432. At this time, the space between the pressing plate 42 and the corresponding first transverse support 30 increases, allowing bamboo strips to be loaded. When the pressing plate 42 leaves the loading station and the fixed stop 432, it is able to swing axially toward the first transverse support 30 around the swinging core 41 under the restoring force of the torsion spring 431, thereby pressing the bamboo strips 1 on the first transverse support 30. The pressing force exerted by the pressing plate 42 on the bamboo strips is an elastic force, which provides conditions for actively clamping and flipping the bamboo strips during the bamboo strips' compression and conveying process, as well as for pushing and unloading the bamboo strips.

[0020] Further, such as Figure 1As shown, the first conveyor belt 20 conveys downward, and the first conveyor belt 20 is composed of two sets of first conveyor chains arranged symmetrically at intervals on the left and right. A lifting and loading mechanism 50 is provided between the two sets of conveyor chains, and the lifting and loading mechanism 50 includes a second conveyor belt 51 capable of conveying upward, and a plurality of second transverse supports 52 are arranged on the second conveyor belt 51 along its conveying direction, for supporting the bamboo pieces 1 to prevent them from falling; the top of the second conveyor belt 52 is higher than the first conveyor belt 20, and material receiving guide slopes 53 are respectively provided on both sides of the top of the second conveyor belt 51, and the material receiving guide slopes 53 are arranged obliquely downward in the direction from the top of the second conveyor belt 51 to the loading station of the first conveyor belt 20. During operation, the bamboo piece 1 is placed horizontally on the second transverse support 52 and is driven upward by the second conveyor belt 51 to the top of the bamboo piece. At the top bend of the second conveyor belt 51, the second transverse support 52 gradually flips from below the bamboo piece to above the bamboo piece. Since the bamboo piece 1 loses the bottom support provided by the second transverse support 52, it will naturally fall onto the material receiving guide inclined surface 53. Under the guidance of the material receiving guide inclined surface 53, it slides toward the loading station of the first conveyor belt 20 and falls onto the first transverse support 30 at the loading station 100, realizing automatic loading of the first conveyor belt 20. Of course, the bamboo piece conveying and pressing device of the present invention is applicable not only to conveyor belts that convey downward, but also to conveyor belts that convey upward.

[0021] like Figure 1 、 Figure 2 As shown, the first transverse support 30 is preferably composed of two first support blocks arranged laterally apart. During operation, the bamboo strip transverse support is mounted on the two first support blocks.

[0022] Further, such as Figure 1 As shown, each first lateral support 30 is provided with a clamping mechanism 40 on both lateral sides. The clamping mechanisms 40 on both sides can be of the same structure (for example, both use the clamping mechanism 40 described in the embodiment of the present invention), or they can be of two different types (one using the clamping mechanism described in the embodiment of the present invention and the other using another type of clamping mechanism) to achieve complementary advantages between the two clamping mechanisms.

[0023] 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 scope of protection of the utility model.
