DETAILED DESCRIPTION

[0017] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0018] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0019] Example: Figures 1 to 4As shown, a material unloading and conveying device for a plastic folding fork provided in an embodiment of the utility model comprises a support seat 5, a bearing plate 6 and a storage box 7. The two sides of the support seat 5 are fixedly connected to the lower side surfaces of the two bearing plates 6. The upper end of the bearing plate 6 is fixedly connected to the two side surfaces of the storage box 7. A discharging device 1 is arranged inside the storage box 7, and a discharging hole is arranged on one side of the storage box 7, leading to the conveying plate 206 below. Among them, the discharging device 1 is used to complete the quantitative unloading operation of the folding fork according to the preset conveying amount. A preferred technical solution: the discharging device 1 comprises a double-headed motor 101, a connecting rod 102, a driving gear 103, a driven gear 104, a transmission rod 105 and a discharging plate 106. The upper output end of the double-headed motor 101 is fixedly connected to the lower end of the connecting rod 102, and is used to drive the connecting rod to rotate synchronously. The upper end of the connecting rod 102 is fixedly connected to the driving gear 103, that is, the driving gear 103 is sleeved and installed on the upper end of the connecting rod 102. The tooth surface of the driving gear 103 is meshed with the tooth surface of the driven gear 104, and both adopt a helical gear structure. The driven gear 104 is sleeved and installed on one end of the transmission rod 105, and the discharge plate 106 is set on the transmission rod 105, and is a plurality of annularly evenly distributed, wherein the discharge plate 106 is a square plate structure or an arc plate structure. The surface of the transmission rod 105 is fixedly connected to the lower end of the discharge plate 106. When one side of the motor is started, it will drive the connecting rod 102 and the driving gear 103 to rotate synchronously. Under the action of gear meshing, it will further drive the transmission rod 105 and the discharge plate 106 to rotate, so that the rotational motion generated by the motor can be accurately converted into the rotation of the transmission rod 105, ensuring the orderly release of the folding fork.

[0020] In this embodiment, a conveying mechanism 2 is provided at the lower end of the support seat 5, and the conveying mechanism 2 is used to convey the folding fork. In a preferred technical solution, the conveying mechanism 2 includes a receiving rod 201, a transmission gear 202, a matching gear 203, a support rod 204, a cam 205 and a conveying plate 206. The receiving rod 201 is vertically distributed, and the lower end is fixedly connected to the transmission gear 202. The tooth surface of the transmission gear 202 is meshed and connected with the tooth surface of the matching gear 203, and the two also adopt a helical gear structure. The matching gear 203 is sleeved and installed on one end of the support rod 204. The support rod 204 is horizontally distributed, and the support rod 204 is also provided with a plurality of uniformly distributed cams 205. The preferred cam adopts an elliptical structure. Of course, the cam can also adopt a structure in which a circular wheel is eccentrically arranged on the support rod, the purpose of which is to drive the conveying plate to perform periodic up and down reciprocating motion. The surface of the cam 205 contacts the lower surface of the conveying plate 206. When the cam 205 rotates in the support seat 5, it periodically moves to contact and push the conveying plate 206, causing the conveying plate 206 to reciprocate up and down. This shaking conveying method not only helps to keep the folding forks on the conveying plate 206 neatly arranged, but also promotes the smooth movement of the folding forks along the predetermined path.

[0021] Among them, the upper surface of the support seat 5 is provided with a plurality of telescopic rods 3, the lower ends of the telescopic rods 3 are fixedly connected to the upper surface of the support seat 5, and the inner wall of the carrier plate 6 is provided with a bearing seat 4, which can be fixed by welding. The surface of the bearing seat 4 is fixedly connected to the inner wall of the carrier plate 6, and is dynamically adjusted according to the movement of the conveying plate 206 through the length of the telescopic rod 3, which helps to compensate for the height change of the conveying plate 206 caused by the rotation of the cam 205, so that the conveying plate 206 is always kept in a relatively horizontal state, forming a shaking effect on the conveying of the folding fork, thereby ensuring the neat arrangement and smooth movement of the folding fork during the conveying process. The surface of the double-headed motor 101 is fixedly connected to the inner wall of the carrier plate 6 through a bracket. The purpose of using a double-headed motor is to achieve bidirectional drive while saving installation space. The two ends of the transmission rod 105 are connected to the inner wall of the storage box 7 through bearings to maintain rotation. The inner end of the discharge plate 106 is connected to the transmission rod 105, and the outer end surface maintains sliding contact with the inner wall of the storage box 7, allowing the discharge plate 106 to move smoothly along a predetermined path in the storage box 7. As the transmission rod 105 rotates, the discharge plate 106 can release the folding forks one by one and in an orderly manner onto the conveying plate 206 in the set direction and speed.

[0022] In this embodiment, the lower end of the double-headed motor 101 is fixedly connected to the upper end of the receiving rod 201, and is used to start the output of the motor on one side to drive the receiving rod 201 to rotate synchronously. The two ends of the support rod 204 are connected to the inner wall of the support seat 5 through bearings to maintain rotation. The surface of the conveying plate 206 is slidably connected to the inner wall of the support seat 5, allowing the conveying plate 206 to move smoothly along a predetermined path inside the support seat 5. With the periodic rotation of the cam 205, the conveying plate 206 can reciprocate up and down in the support seat 5, ensuring that the folding fork can be neatly arranged and moved along a preset path. Among them, the upper end of the telescopic rod 3 is fixedly connected to the lower surface of the conveying plate 206, and the inner walls of the two bearing seats 4 are respectively connected to the connecting rod 102 and the receiving rod 201 to maintain rotation. The bearing seat 4 provides a low-friction rotation support point, which reduces the friction between the rotating parts and reduces mechanical wear.

[0023] The working principle of the utility model is as follows: during the unloading process of the plastic folding fork, the operator pours the finished folding fork into the storage box 7, and after starting the double-headed motor 101, the connecting rod 102 and the receiving rod 201 are driven to rotate through the output ends on both sides. On the output side of the motor, the connecting rod 102 is connected to the driving gear 103, and the driving gear 103 is meshed with the driven gear 104, and the power transmission chain formed thereby finally acts on the transmission rod 105 in the storage box 7. Since a number of discharge plates 106 are evenly distributed on the transmission rod 105, the gaps between these discharge plates 106 constitute a temporary bearing space for the folding fork. As the transmission rod 105 rotates in a preset direction, the folding forks in each discharge plate 106 are output in sequence. This process ensures that the folding forks leave the storage box 7 in a predetermined number and order and accurately fall on the conveying plate 206 below. At the same time, on the other side of the motor output, the lower end of the receiving rod 201 is fixedly connected to the transmission gear 202, and the transmission gear 202 is meshed with the matching gear 203, thereby driving the support rod 204 and the cam 205 installed thereon to rotate. When the cam 205 rotates in the support seat 5, it periodically contacts and pushes the conveying plate 206, causing it to reciprocate up and down. This shaking conveying method helps to keep the folding forks on the conveying plate 206 neatly arranged and promotes the movement of the folding forks along a predetermined path. In order to ensure the smooth operation of the conveying plate 206, a telescopic rod 3 is provided at its bottom to maintain a stable position. In addition, the guide groove opened on the surface of the conveying plate 206 further assists in controlling the unloading direction of the folding fork to ensure that each folding fork can smoothly enter the subsequent processing.
