Description

Technical Field

[0001] The invention belongs to the technical field related to bamboo winding, and particularly relates to a bamboo strip feeding machine. Background Art

[0002] Bamboo material is a renewable, green and environmentally friendly material with good structural properties, suitable for a variety of application environments. With the continuous maturity and development of bamboo winding technology, the application of bamboo winding products has become more and more extensive, and has been widely used in many fields such as bamboo winding houses, bamboo winding corridors, and bamboo winding pipelines.

[0003] In the molding process of bamboo winding products, bamboo strips curtain plays a very important role, and it is often used as the "raw material" or "base material" of bamboo winding products. Generally speaking, bamboo strips curtain is obtained by weaving bamboo strips or bamboo strips into a "curtain-like" structure, and then by performing corresponding winding, bonding and other processing processes on the bamboo strips curtain, the corresponding bamboo winding products can be obtained.

[0004] For the forming of bamboo strips curtains, the traditional method is to complete the loading of bamboo strips or bamboo strips by manual wire feeding, and then complete the weaving process of bamboo strips curtains. This method has high labor costs and low forming efficiency of bamboo strips curtains, which cannot fully meet the needs of mass production, resulting in high production costs of bamboo winding products. In order to avoid the defects of traditional manual wire feeding, production and research personnel considered that the relevant wire feeding process can be completed by the corresponding wire feeding machine to improve the preparation efficiency of bamboo strips curtains. In the field of mechanical wire feeding, the more common ones are related equipment for metal wire feeding. Since the metal wire is often in a coiled shape before feeding, the wire feeding process often includes two processes: straightening and straight wire feeding. This is very different from the feeding form of bamboo strips or bamboo sheets when weaving bamboo curtains. Bamboo strips are often in long strips when feeding, and are fed in bundles or handfuls. The difference in feeding form makes the existing metal wire feeding equipment unable to be effectively applied to the feeding of bamboo strips, because there is a risk of breaking the bamboo strips when feeding bamboo strips.

[0005] At the same time, in the existing patent CN 104786310 A, a wire feeding device for a bamboo or rattan weaving machine is provided, which includes a wire feeding frame seat, a lining frame assembly, a wire arrangement assembly, a wire clamping wire feeding assembly and a wire feeding switch assembly, wherein the lining frame assembly is installed on the upper part of the wire feeding frame seat, the wire arrangement assembly is installed in the lining frame assembly on the upper part of the wire feeding frame seat and the middle and lower part of the wire feeding frame seat, the wire clamping wire feeding assembly is installed on the left middle part and the right middle and lower part of the wire feeding frame seat, and the wire feeding switch assembly is installed on the middle and lower part of the front and rear sides of the wire feeding frame seat. The above-mentioned wire feeding device can realize the separation and automatic transportation of bamboo or rattan wires to a certain extent, but the above-mentioned device has a complex structure and is difficult to repair and maintain. Moreover, it adopts a striker structure to complete the wire feeding, which is prone to device failure, causing the bamboo or rattan wire to break, and then inevitably produces debris and residues, blocking the wire feeding channel, so that the wire feeding process is blocked and manual cleaning is required, resulting in low wire feeding efficiency.

[0006] In short, the existing wire feeding device cannot fully meet the requirements of fast and stable wire feeding of bamboo strips, and the efficiency of bamboo strip wire feeding is low and has certain limitations. Summary of the invention

[0045] Furthermore, in order to achieve orderly storage of bamboo strips in the feed hopper 1, a wedge-shaped vibration component 2 is correspondingly provided on one side of the feed hopper 1, such as Figure 4 and Figure 5 As shown in the figure, it includes a wedge-shaped fixing plate 203 which is vertically arranged and has a plate-like structure. The plate surface of the wedge-shaped fixing plate 203 is arranged opposite to the wedge-shaped cavity of the feed hopper 1, and a top notch is opened on the top thereof. The top of the top notch is triangular and is aligned with the wedge-shaped cavity of the feed hopper 1 in the horizontal direction, that is, the top notch of the top notch of the wedge-shaped fixing plate 203 is wide at the top and narrow at the bottom, and the bottom of the top notch is provided with a rectangular notch of a certain depth corresponding to the rectangular slit of the feed hopper 1, the width of the rectangular notch is not less than the width of the rectangular slit, and is aligned with the rectangular slit in the horizontal direction, and the height of the bottom of the rectangular notch is lower than the setting height of the rectangular slit.

[0047] More specifically, a plurality of vertical long grooves penetrating the two side end faces are provided on the plate surface of the wedge-shaped movable plate 202, and a guide piece is provided on the wedge-shaped fixed plate 203 corresponding to each vertical long groove, so that each guide piece can be correspondingly embedded in the vertical long groove on the wedge-shaped movable plate 202, and then the wedge-shaped movable plate 202 can repeatedly move vertically under the guidance of each guide piece. When the wedge-shaped movable plate 202 moves to the highest point or the lowest point, each guide piece is preferably located at the lowest point and the highest point of the corresponding vertical long groove. Further preferably, a guide piece is provided at the bottom of the wedge-shaped movable plate 202 as follows: Figure 4 The cam 201 shown in the figure is provided with a vibration motor 204 corresponding to the cam 201, which controls the rotation of the cam 201 through a chain 205, and then controls the cam 201 to lift or lower the wedge-shaped movable plate 202, so as to realize the reciprocating motion of the wedge-shaped movable plate 202 in the vertical direction.

Moreover, by setting the wedge-shaped vibration component 2, a large number of bamboo strips can be stacked in the feed hopper 1 at the same time, avoiding frequent loading of the feed hopper 1 during the bamboo strip feeding process.

[0049] Further preferably, a feeding hopper 5 is provided on the side of the wedge-shaped vibration component 2 facing away from the feed hopper 1, which includes a hopper 501 with a "U-shaped" or "V-shaped" cross-section and arranged at a certain inclination angle, and a bracket 502 arranged at the bottom of the hopper 501, and the hopper 501 is supported by the bracket 502; further, the end of the hopper 501 with a lower vertical height is directly opposite to the top notch of the wedge-shaped vibration component 2, and the vertical height of the end of the hopper 1 on this side is not lower than the top of the wedge-shaped vibration component 2, so that the bamboo strips material in the hopper 501 can be continuously fed into the feed hopper 1, avoiding continuous manual feeding during the bamboo strips feeding process, saving labor costs, and ensuring the stability of bamboo strips feeding.

[0050] Further preferably, in the preferred embodiment, a sensor is respectively provided at the tail end of the bamboo strip feeder and the front end of the weaving machine. By sensing the ends of the bamboo strips through the two sensors, the length of the bamboo strips can be detected accordingly. At the same time, a limiter is provided on the weaving machine to control whether the weaving machine is working, and then the sensor and the limiter are linked for control. When the length of the bamboo strips meets the normal requirements, the sensor does not link the limiter, and the weaving machine performs the weaving action normally; when the length of the bamboo strips is too long or too short, the sensor links the limiter, so that the weaving machine does not move or moves in the opposite direction, and the bamboo strips with unqualified length do not enter the weaving machine but directly enter the waste hopper.

[0051] The bamboo strips feeder in the present invention takes into account the characteristics of bamboo strips themselves, such as high toughness, easy breakage and low rigidity. By correspondingly arranging a feed hopper, a wedge-shaped vibration component, a transmission component and a vacuum adsorption component, the bamboo strips can be accurately and stably adsorbed on a transmission belt and accurately transmitted along the length direction, thereby achieving accurate matching between the bamboo strips and the roller, reducing the breakage and damage of the bamboo strips during the feeding process, reducing the breakage rate of raw materials, saving the preparation cost of bamboo winding products, and thus avoiding manual cleaning during the bamboo strips feeding process, saving the labor cost during the bamboo strips feeding process, reducing possible mechanical failures of the bamboo strips feeder, ensuring the continuity and stability of the bamboo strips feeding, and having good application prospects and promotion value.
