[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example 1: A stepped feeding device for rubber balls, referring to... Figure 1 It includes a base 111, which is a metal frame, and a stepped feeding assembly 112 is installed on the base 111. The stepped feeding assembly 112 is a prior art Chinese patent document with publication number CN105645081A and titled Stepped feeding assembly 112, which has disclosed its structure and principle. This solution will not elaborate on the principle of the stepped feeding assembly 112.

[0020] The base 111 is also equipped with a material trough 113, which is a metal sheet metal trough. The bottom of the material trough 113 and the stepped feeding assembly 112 are connected by screws. The stepped feeding assembly 112 conveys the rubber ball in the material trough 113 to the top. The stepped feeding assembly 112 pushes the rubber ball in the feed trough 113 from bottom to top. The top of the stepped feeding assembly 112 has a downward sloping plate 114, which is welded and fixed to the base 111.

[0021] The lower end of the ramp 114 is provided with a conveyor belt 115; the conveyor belt 115 is mounted on the base 111, so the stepped feeding assembly 112 sends the rubber ball to the ramp 114, and then rolls it from the ramp 114 to the conveyor belt 115.

[0022] The base 111 is equipped with a second motor 120, which drives the conveyor belt 115 to rotate.

[0023] Figure 2In the middle, the base 111 is fixed with a surrounding plate 400, which is a bent metal plate; The 400mm perimeter panel is divided into three parts; The enclosure 400 is located above the conveyor belt 115. This design does not affect the operation of the conveyor belt 115 and keeps the uploaded rubber ball within the enclosure of the enclosure 400.

[0024] The first part of the enclosure 400 spans the conveyor belt 115 and is connected to the downslope 114. This design prevents the rubber ball from leaking out from one end of the conveyor belt 115. The second part of the enclosure 400 is located on one side of the conveyor belt 115, and the second part and the downslope 114 are located on both sides of the conveyor belt 115. This design reduces the leakage of rubber balls from both sides of the conveyor belt 115. The third part of the enclosure panel 400 is the first bonding panel 601; A constriction assembly for single-strand rubber balls is provided above the conveyor belt 115, and the constriction assembly is located below the enclosure 400 along the conveying direction of the conveyor belt 115. Figure 2 In the middle, the necking assembly includes an inclined guide plate 117 and a discharge guide plate 118, and the inclined guide plate 117 and the surrounding plate 400 are fitted together. The inclined guide plate 117 guides the rubber ball to the discharge guide plate 118; the combination of the inclined guide plate 117 and the discharge guide plate 118 causes the path space of the rubber ball to gradually narrow from the inlet end to the outlet end, forming a funnel-like "wide opening in, narrow opening out" gradually narrowing channel structure, so that the rubber ball can only pass through the ends of the inclined guide plate 117 and the discharge guide plate 118 individually. Reference Figure 1 and Figure 2 The discharge guide plate 118 is provided with an opening 119 for the stacked rubber balls to slide out. The opening 119 and the material trough 113 are connected by a guide groove 300. The guide groove 300 is provided below the opening 119. The upper end of the guide groove 300 is connected to the opening 119, and the lower end of the guide groove 300 is connected to the material trough 113.

[0025] The lower edge of the opening 119 is higher than the upper surface of the conveyor belt 115; for the rubber balls on the conveyor belt 115, the top of the rubber balls is higher than the lower edge of the opening 119. When a large number of rubber balls accumulate at the discharge guide plate 118, the opening 119 is used to collect excess rubber balls to prevent them from rolling outwards.

[0026] The end of the constriction assembly, that is, the end of the inclined guide plate 117 and the discharge guide plate 118, is connected to a path that allows the rubber ball to pass through in single strands, namely the single strand channel 200.

[0027] The single-channel 200 includes a first limiting plate 201 fixed to the end of the discharge guide plate 118; the single-channel 200 also includes a second limiting plate 202 fixed to the base 111. The first limiting plate 201 and the second limiting plate 202 are arranged in parallel above the conveyor belt 115; and the width between the first limiting plate 201 and the second limiting plate 202 is slightly larger than the diameter of the rubber ball so that the rubber ball can pass through the first limiting plate 201 and the second limiting plate 202 one by one. "Slightly larger" means that the width value is 1%-10% larger than the diameter value. This design ensures that the rubber ball passes through the single-channel 200 one by one.

[0028] The ends of the second limiting plate 202 and the inclined guide plate 117 are smoothly connected.

[0029] Reference Figures 5-6 The end of the single channel 200 is provided with a discharge pipe 700, which is fixed to the machine base 111 by screws. The upper end of the discharge pipe 700 is provided with a side hole 701, which connects to the single channel 200. The lower end of the discharge pipe 700 is provided with a discharge port 116. In this way, the rubber ball on the single channel 200 changes from moving laterally on the conveyor belt 115 to moving vertically out of the discharge pipe 700.

[0030] Example 2: A stepped feeding device for rubber balls, which differs from Example 1 in that, referring to... Figure 3 and Figure 4 The machine base 111 is provided with a slide groove 501, which is a straight groove. A slider 502 slides on the slide groove 501. An inclined guide plate 117 is fixed on the slider 502. The slide groove 501 and the conveyor belt 115 are arranged perpendicularly. Reference Figures 2-3 When the slider 502 slides back and forth, the size of the narrowing of the inclined guide plate 117 and the discharge guide plate 118 can be adjusted.

[0031] The base 111 and the slider 502 are connected by a lead screw 503. The two ends of the lead screw 503 are connected to the base 111 through bearings, so the lead screw 503 can rotate on the base 111. The length direction of the lead screw 503 is the same as the length direction of the groove 501. The lead screw 503 and the slider 502 are threaded together. When the lead screw 503 rotates, the slider 502 can only move back and forth along the groove 501 because it is constrained by the groove 501.

[0032] The threads of both the lead screw 503 and the slider 502 have a certain degree of stability, and the squeezing force of the rubber ball on the inclined guide plate 117 is insufficient to cause the slider 502 to loosen.

[0033] A knob 504 is provided at one end of the lead screw 503. The position of the slider 502 is adjusted by rotating the knob 504, thereby adjusting the position of the inclined guide plate 117. The purpose of this design is to allow the constriction assembly to accommodate rubber balls of more sizes.

[0034] A first bonding plate 601 is fixed to the edge of the enclosure 400, and a second bonding plate 602 is provided on the edge of the inclined guide plate 117. The first bonding plate 601 and the second bonding plate 602 are bonded together. Both the first bonding plate 601 and the second bonding plate 602 are metal plates, and there is elastic compression between them, which makes the first bonding plate 601 and the second bonding plate tightly bonded together.

[0035] When the inclined guide plate 117 moves, the first bonding plate 601 and the second bonding plate 602 remain in a bonded state, and the connection between the inclined guide plate 117 and the surrounding plate 400 remains sealed.

[0036] Similarly, when the inclined guide plate 117 is adjusted, the size of the single channel 200 also needs to be adjusted accordingly; The second limiting plate 202 is bent and includes a vertical plate and a horizontal plate. The horizontal plate has three oblong holes 203 arranged in a straight line. The second limiting plate 202 is fixed to the base 111 by three screws. Therefore, the second limiting plate 202 moves along the length of the oval hole 203 to adjust its position so as to smoothly connect with the inclined guide plate 117 after the adjustment. The movement of the second limiting plate 202 also adjusts the width of the single channel 200. This design is to enable the feeding device to accommodate more sizes of rubber balls.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
