Description

Technical Field

[0001] The invention belongs to the technical field of hand mold cleaning equipment, and in particular relates to a multi-stage roller brush machine for a plastic glove production line. Background Art

[0002] In the process of making plastic gloves, the hand mold is usually immersed in latex and then dried. Before the hand mold enters the next cycle, the gloves on the hand mold may not fall off. The hand mold needs to be cleaned to ensure that it is clean. At present, the main solution is manual work, but the temperature and noise in the glove production workshop are high, and long working hours cause certain physical harm to workers. In addition, the workload of manual cleaning of hand molds is large, and negligence is inevitable, which leads to quality problems of plastic gloves.

[0003] Among the known automatic hand mold cleaning technologies, the brush cleaning structure is simple and is widely used in the market. However, there are many defects in actual use. First, the brushing direction is vertically downward along the hand mold. The hand mold moving horizontally at high speed is easily affected by the lateral force of the brush, resulting in damage to the hand mold, such as the finger part is easily broken; second, the existing brushes are all flat brushes, and the shape of the hand mold is a complex curved surface. As the glove curls downward along the hand mold, the brushing force required becomes greater and greater, and it is difficult to ensure a good brushing effect with a flat brush.

[0022] like Figure 1 As shown, the multi-stage roller brush machine for a plastic glove production line provided by the present invention comprises a roller brush assembly A, a bracket assembly B and a driving mechanism C. The roller brush assembly A is mounted on the bracket assembly B. The roller brush assembly A comprises a plurality of roller brushes symmetrically distributed along both sides of the hand mold and arranged in a stepped manner on each side. The multi-stage roller brush machine provided in this embodiment also comprises a material receiving box D, which is arranged on the bottom bracket and directly below the hand mold to receive the gloves brushed off by the roller brush.

[0023] See also Figure 2 Each roller brush A1 in the stepped roller brush is installed independently, and each roller brush A1 can be removed separately. If a single roller brush needs to be replaced during use, the trouble of disassembling the whole roller brush can be avoided. Multiple roller brushes A1 are arranged from high to low along the movement direction of the hand model and have the same rotation direction. Different parts of the hand model are brushed from top to bottom, that is, the wrist, palm and fingers of the hand model are brushed in turn, which can reduce the contact area between a single roller brush A1 and the hand model, thereby reducing the damage to the hand model.

[0024] See also Figure 3 The roller brush assembly A also includes a driving motor A2, a gear box (not shown in the figure) and a roller brush support A3. The roller brush A1, the driving motor A2 and the gear box are all mounted on the roller brush support A3, wherein the roller brush A1 and the gear box are fixed by a flange. The driving motor A2 drives the first roller brush through a synchronous belt, and the first roller brush sequentially transmits power through the gear box to drive other roller brushes to rotate, wherein the transmission ratio of the gear box is 1.

[0025] Combination Figure 4 , the hand model moves in the horizontal direction, the roller brush moves in the inclined direction, and the roller brush movement speed Vs is decomposed into the horizontal component speed Vs according to the inclination angle 1 and vertical velocity Vs 2 , where the horizontal velocity of the roller brush is Vs 1 The same speed as the hand model. At this time, after the roller brush movement speed Vs is decomposed, relative to the moving hand model, only the vertical component speed Vs2 remains, which can successfully brush the glove from the hand model. In actual operation, if the horizontal inclination angle of the roller brush is ɑ, and the speed of the hand model is the preset value, that is, Vs 1 , then we can get the roller brush movement speed Vs = Vs1 / cosɑ.

[0026] See also Figure 5 The bracket assembly B includes a bottom bracket B1 and an angle bracket B2. The angle bracket B2 is installed on the bottom bracket B1. The bottom bracket B1 is a rectangular frame, and the bottom of the rectangular frame has four legs B11 whose heights can be adjusted individually. The plane where the angle bracket B2 contacts the roller brush assembly is an inclined surface from high to low along the direction of the hand model movement speed Vm, and multiple roller brushes are installed obliquely along the inclined surface. Among them, the driving mechanism C is fixedly installed on the angle bracket B2 through a fixing member B21. Preferably, in order to save equipment space, the side section of the angle bracket B2 provided in this embodiment is designed to be trapezoidal. In actual applications, the side section of the angle bracket B2 can be other shapes such as a rectangle, which is not limited by the present invention.

[0027] See also Figure 6 The driving mechanism C includes a cylinder (not shown in the figure) and an opening and closing assembly C1. The cylinder drives the opening and closing assembly C1, and the opening and closing assembly C1 controls the opening and closing of the roller brush on both sides of the plastic hand model. The opening and closing assembly C1 includes a front slide rail C11, a rear slide rail C12, a left front rocker arm C13, a left rear rocker arm C14, a right front rocker arm (not shown in the figure, the same as and symmetrical to the left front rocker arm C13), a right rear rocker arm (not shown in the figure, the same as and symmetrical to the left rear rocker arm C14), a left rocker bar C15 and a right rocker bar (not shown in the figure, the same as and symmetrical to the left rocker bar C15). The front slide rail C11 and the rear slide rail C12 are installed on the angle bracket B2, and the front slide rail C11 and the rear slide rail C12 are respectively installed with roller brush assemblies, the left rocker C15 is respectively connected to the left side of the front slide rail C11 and the rear slide rail C12 through the left front rocker arm C13 and the left rear rocker arm C14, and the right rocker is respectively connected to the right side of the front slide rail C11 and the rear slide rail C12 through the right front rocker arm and the right rear rocker arm. The cylinder drives the left rocker C15 and the right rocker arm to swing, and drives the front slide rail C11 and the rear slide rail C12 to open and close on both sides of the hand model through the left front rocker arm C13, the left rear rocker arm C14, the right front rocker arm and the right rear rocker arm.

[0028] In summary, the multi-stage roller brush machine for the plastic glove production line provided in accordance with the preferred embodiment of the present invention is provided with a plurality of roller brushes symmetrically distributed along the two sides of the hand model and arranged in a stepped manner on each side. The plurality of roller brushes sequentially brush different parts of the hand model from top to bottom, that is, sequentially brush the wrist, palm and fingers of the hand model from high to low, thereby reducing the contact area between a single roller brush and the hand model and reducing damage to the hand model. In addition, the movement direction of the roller brush is set to be inclined from high to low along the movement direction of the hand model, wherein the movement direction of the hand model is horizontal, and the movement speed of the roller brush is decomposed into a horizontal component speed and a vertical component speed according to the inclination angle, wherein the horizontal component speed of the roller brush movement is the same as the speed of the hand model movement. In this way, the lateral force generated by the roller brush during the movement of the hand model is eliminated.

[0029] The above description is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
