Description

Technical Field

[0001] The utility model belongs to the technical field of bamboo fork and spoon production and processing equipment, in particular to a feeding device for avoiding knots and removing defective products in the production of bamboo products. Background Art

[0002] In bamboo product production, especially in tableware like forks and spoons, specific measures and equipment are used to avoid using parts of the bamboo material with knots or other defects to ensure the quality of the final product. This is known as "avoiding knots and removing defective products." A bamboo knot is a ring-shaped protrusion inherent in the bamboo stem, while "defective products" refer to products that do not meet product quality requirements.

[0003] Existing bamboo blanks are usually transported by conveyors, and reflective photoelectric sensors are used to detect bamboo nodes and defects on their surfaces during the transportation process, so as to achieve the purpose of distinguishing defective bamboo pieces. However, the existing device lacks a structure that can turn the bamboo blanks over, making it difficult for the device to detect both sides of the bamboo pieces, which makes it easy for damaged pieces to be missed, thereby reducing the production and processing quality of bamboo forks and spoons.

[0004] In summary, there is a need for a loading device that can flip the material over to avoid knots and remove defective products for inspection. Utility Model Content

[0005] The utility model aims to provide a feeding device for avoiding knots and removing defective products in the production of bamboo products. The device utilizes the hinged connection between the horizontal plate and the conveying mechanism to cause the vertical plate to drive the horizontal plate to flip. During the flipping process, the horizontal and vertical plates are flipped by various magnets, thereby achieving the purpose of turning over the bamboo blanks on the surface of the horizontal plate.

[0006] The technical solution adopted by the utility model to solve the above problems is: a feeding device for avoiding knots and removing defective products in the production of bamboo products, comprising:

[0007] Conveying mechanism;

[0008] A defective product detection device, the defective product detection device comprising a first bracket fixedly connected to the top of the conveying mechanism, two first brackets being respectively provided in the front and rear along the conveying direction of the conveying mechanism, a reflective photoelectric sensor being fixedly connected to the front first bracket, a first controller being fixedly connected to the front first bracket, and a second controller being fixedly connected to the rear first bracket;

[0009] An automatic flipping assembly includes a horizontal plate hinged at one end to the top of the conveying mechanism, a vertical plate fixedly connected to one side of the top of the horizontal plate, a first magnet block fixedly connected to one side of the bottom of the horizontal plate, a second magnet block fixedly connected to one side of the vertical plate, and a third magnet block and a fourth magnet block fixedly connected to the conveying surface of the conveying mechanism.

[0010] A further preferred technical solution is that the defective product detection device further includes:

[0011] A material unloading slot is provided on the horizontal plate and the vertical plate respectively. A material baffle plate is rotatably connected to the interior of the material unloading slot via a rotating shaft. A first motor is fixedly connected to the horizontal plate and the rotor ends of the first motor are coaxially fixedly connected to the rotating shaft respectively. A second motor is fixedly connected to the vertical plate and the rotor ends of the second motor are coaxially fixedly connected to the rotating shaft respectively.

[0012] A further preferred technical solution is that the automatic flipping assembly further comprises:

[0013] The second bracket is fixedly connected to the conveying mechanism and is located between the two groups of first brackets. A blocking rod is fixedly connected to the second bracket.

[0014] A further preferred technical solution is that the conveying mechanism is composed of two groups of conveyors, and the conveying surfaces of the two groups of conveyors are on the same horizontal line.

[0015] A further preferred technical solution is that the magnetic pole directions of the contact surfaces of the first magnet block and the third magnet block are opposite to each other.

[0016] A further preferred technical solution is that the magnetic pole directions of the contact surfaces of the second magnet block and the fourth magnet block are opposite to each other.

[0017] Here, the magnetic pole direction refers to the direction of the south pole and the north pole of the magnet. In common magnets, there is usually a mark to indicate the polarity of the magnetic field, for example, N represents the north pole and S represents the south pole. Therefore, the opposite magnetic pole directions mentioned in the description mean that between the opposite magnetic poles of the first and third magnet blocks and the second and fourth magnet blocks, one is the north pole and the other is the south pole; or one is the south pole and the other is the north pole. In addition, in the case where the magnetic pole directions between the respective contact surfaces of the second magnet block and the fourth magnet block are oppositely set, this means that on the surfaces of the second magnet block and the fourth magnet block that contact each other, the north pole of one corresponds to the south pole of the other, and vice versa.

[0018] A further preferred technical solution is that a gap is left between the two groups of conveyors, a defective product collection box is provided below the conveying mechanism, and the width of the defective product collection box is larger than the size of the gap.

[0019] By leaving a gap between the two conveyor sets and placing a defective product collection box below that is wider than the gap, it is possible to ensure that defective products falling from either conveyor are effectively collected in the defective product box. This design means that no matter which direction or position the defective products fall from, there is a high probability that they will fall into the collection box, thus reducing the risk of missing defective products.

[0020] A further preferred technical solution is that the sum of the areas of the two groups of baffle plates is consistent with the area of ​​the material discharge slot.

[0021] A further preferred technical solution is that the area of ​​the horizontal plate is consistent with the area of ​​the vertical plate.

[0022] Consistent size means that the total area of ​​the two sets of baffles (the sum of the areas of each set of baffles) is the same as the area of ​​the discharge chute. This design may be to ensure that the discharge chute is completely covered by the baffles to control the flow of materials or distribute materials to a specific location. Similarly, consistent size also means that the areas of the horizontal and vertical plates are equal. This design helps maintain the stability of the equipment or ensure uniform force distribution.

[0023] In summary, the present invention has the following advantages:

[0024] 1. In the process of the conveying mechanism driving the bamboo blank to move, the vertical plate will be hindered after contacting the baffle rod. At this time, the hinged effect between the horizontal plate and the conveying mechanism is utilized to enable the vertical plate to drive the horizontal plate to flip, and the baffle rod 208 will not affect the horizontal plate 201 during the flipping process. When it flips to a certain angle, the second magnet block and the fourth magnet block are close to each other, so that the second magnet block and the fourth magnet block are adsorbed together. At this time, both the horizontal plate and the vertical plate complete a 90-degree flip, thereby achieving the purpose of turning over the bamboo blank on the surface of the horizontal plate, effectively avoiding the situation where the bamboo blank is difficult to flip over, which is easy to be damaged or missed, thereby reducing the production and processing quality problems of the bamboo fork and spoon.

[0025] 2. The utility model can detect the bamboo blanks on the conveying mechanism through the reflective photoelectric sensor. When bamboo nodes or damage are detected on the surface of the bamboo blank, the first controller or the second controller is used to control the first motor or the second motor to rotate respectively. The first motor or the second motor drives the two sets of baffles to rotate inward respectively, so that the baffles can fall and be recycled in the defective collection box, thereby achieving the purpose of removing defective products and effectively ensuring the production and processing quality of bamboo forks and spoons.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0032] Example:

[0033] Please combine Figure 1-3 The present embodiment provides a feeding device for avoiding knots and removing defective products in the production of bamboo products, comprising:

[0034] Conveying mechanism 1 is composed of two sets of conveyors. The conveying surfaces of the two sets of conveyors are on the same horizontal line, which can ensure the horizontal and stable conveying of bamboo blanks, thereby facilitating detection;

[0035] The defective product detection device includes a first bracket 101 symmetrically fixedly connected to the top of the conveying mechanism 1. Two first brackets 101 are respectively provided in the front and rear directions of the conveying mechanism 1. A reflective photoelectric sensor 102 is fixedly connected to the first bracket 101 on the front side. A first controller 103 is fixedly connected to the first bracket 101 on the front side. A second controller 104 is fixedly connected to the first bracket 101 on the rear side. The model of the reflective photoelectric sensor 102 is E18-D80NK, and the model of the controller is PLC controller M238. Both are existing technical equipment, so they will not be described in detail here.

[0036] The defective product detection device also includes:

[0037] The material unloading slot is respectively opened on the horizontal plate 201 and the vertical plate 202. The interior of the material unloading slot is symmetrically connected to the baffle plate 105 through the rotating shaft. The first motor 106 is symmetrically fixedly connected to the horizontal plate 201 and the rotor ends of the first motor 106 are coaxially fixedly connected to the rotating shaft. The second motor 107 is symmetrically fixedly connected to the vertical plate 202 and the rotor ends of the second motor 107 are coaxially fixedly connected to the rotating shaft. The angle between the horizontal plate 201 and the vertical plate 202 is ninety degrees. The sum of the areas of the two groups of baffle plates 105 is consistent with the area of ​​the material unloading slot, and the area of ​​the horizontal plate 201 is consistent with the area of ​​the vertical plate 202.

[0038] The automatic flipping assembly includes a horizontal plate 201 hinged at one end to the top of the conveying mechanism 1, a vertical plate 202 is fixedly connected to one side of the top of the horizontal plate 201, a first magnet block 203 is symmetrically fixedly connected to one side of the bottom of the horizontal plate 201, and a second magnet block 204 is symmetrically fixedly connected to one side of the vertical plate 202. The third magnet block 205 and the fourth magnet block 206 are symmetrically fixedly connected to the conveying surface of the conveying mechanism 1. The magnetic pole directions of the contact surfaces of the first magnet block 203 and the third magnet block 205 are oppositely arranged, so that the first magnet block 203 and the third magnet block 205 are adsorbed together, thereby ensuring the stability of the automatic flipping assembly when moving, and the magnetic pole directions of the contact surfaces of the second magnet block 204 and the fourth magnet block 206 are oppositely arranged, so that the second magnet block 204 and the fourth magnet block 206 are adsorbed together, thereby ensuring the stability of the automatic flipping assembly when moving after flipping.

[0039] The automatic flip component also includes:

[0040] The second bracket 207 is fixedly connected to the conveying mechanism 1 and is located between the two groups of first brackets 101. A blocking rod 208 is symmetrically fixedly connected to the second bracket 207 and is an L-shaped structure.

[0041] The implementation principle of a loading device for avoiding knots and removing defective products in the production of bamboo products in the embodiment of the present application is as follows: first, the bamboo chip stock is placed on the surface of the baffle plate 105 on the horizontal plate 201, and then the conveying mechanism 1 is started for conveying. When the bamboo chip stock moves to the bottom of the first bracket 101 on the left, the conveying mechanism 1 stops conveying, and then the reflective photoelectric sensor 102 is used to detect the surface of the bamboo chip stock. When there are bamboo knots or damage in the bamboo chip stock, the first controller 103 is controlled by the transmission of electrical signals to drive the two groups of first motors 106 to drive the two groups of baffle plates 105 to rotate inward at the same time, so that the bamboo chip stock on its surface falls off, thereby achieving the purpose of removing defective bamboo chip stock. When the bamboo chip stock is good, the conveying mechanism 1 is started to continue conveying. When the vertical plate 202 contacts the baffle rod 208, it will receive When the first and second magnet blocks 203 and 205 are separated, the second magnet block 204 and the fourth magnet block 206 are attracted to each other, and the horizontal plate 201 and the vertical plate 202 are both turned 90 degrees, thereby achieving the purpose of turning over the bamboo blank on the surface of the horizontal plate 201. Since the friction between the bamboo blank and the baffle plate 105 is large enough, the bamboo blank will not slide down during the turning process. The above operation is then repeated to detect the other side of the bamboo blank, and finally the intact bamboo blank can be transported away.

[0042] In addition, further improvements are: a gap is left between the two groups of conveyors, and a defective product collection box 2 is symmetrically arranged below the conveying mechanism 1. The width of the defective product collection box 2 is larger than the size of the gap, so that the defective bamboo chip blanks can fall smoothly into the defective product collection box 2 for recycling to prevent waste of raw materials.

The drawings are presented in simplified form and are not drawn to exact scale. For convenience and clarity only, directional terms such as top, bottom, left, right, upward, above, above, below, below, rear, and front may be used in the drawings. These and similar directional terms should not be construed as limiting the scope of this disclosure in any way.
