[0039] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] like Figure 1-Figure 3 As shown together, a horizontal extrusion molding machine comprises: a frame 1, the frame 1 is provided with a diversion filling mechanism 2, a molding die 3, a cutting mechanism 4 and a conveying mechanism;

[0041] The diversion filling mechanism 2 is used to divide the received raw materials into several portions, and supply the divided raw materials to the forming mold 3. Along the moving direction of the raw materials, the diversion filling mechanism 2 includes a feed pipe 21, a distribution pipe 22 and a plurality of distributors 23 arranged in sequence. The feed pipe 21 is connected to the distribution pipe 22. The distributor 23 is provided with a distributor feed port 235 and a distributor discharge port 236. The distributor feed port 235 is connected to the distribution pipe 22. The distributor discharge ports 236 are equal in number to the forming mold 3 and are connected one by one. All distributors 23 are driven by a servo motor 24 to move synchronously. A pressure sensor 25 for detecting the pressure of the raw materials is provided on the distribution pipe 22. If the feed pressure value detected by the pressure sensor 25 is within the standard range, the servo motor 24 outputs a portion of raw materials of the same weight as the product 6 each time the distributor 23 is driven to move.

[0042] The forming mold 3 is used to receive a portion of the raw material output by the distributor 23 and form the raw material into a required shape. The forming mold 3 outputs the formed raw material horizontally;

[0043] The cutting mechanism 4 is used to cut the raw material formed by the forming mold 3 into products 6, such as Fig.10 As shown, the cutting mechanism 4 obtains products 6 of the same size and weight each time it cuts;

[0044] The conveying mechanism is preferably a horizontal belt conveyor 5 , which is used to output the product 6 .

[0045] like Fig. 9 As shown, the feed pipe 21 is a three-way Y-shaped pipe, one port of which is connected to the screw extruder, and the other two ports are connected to the feed pipe 22, so that the raw material from the screw extruder is evenly distributed in the feed pipe 22, and the raw material evenly enters each feeder 23, and the servo motor 24 drives each feeder 23 to move synchronously once, and each feeder 23 synchronously outputs a portion of raw material to the molding mold 3. At the same time, the pressure sensor 25 detects the pressure of the raw material in the feed pipe 22 (i.e., the feed pressure) in real time; if the detected feed pressure value is within the set standard range, the servo motor 24 drives each feeder 23 to move and output a portion of raw material with the same weight as the product 6; if it is detected that the feed pressure deviates from the set standard range, it is necessary to adjust the output pressure of the screw extruder so that the feed pressure is within the standard range, to ensure that each feeder 23 outputs a portion of raw material with the same weight as the product 6 each time it moves, to ensure that the size and weight consistency of the final product 6 is good.

[0046] The diverter filling mechanism is equipped with a servo motor 24 and a pressure sensor 25, which overcomes the disadvantages of the previous non-powered transmission, controls the low pressure level, has no pressure peak, achieves consistent portioning accuracy, and truly ensures that the product is uniform during the production cycle.

[0047] like Figure 8As shown, the cutting mechanism 4 includes a horizontal guide rail 401 arranged along the conveying direction of the belt conveyor 5, a horizontal slide 402 sliding on the horizontal guide rail 401, a horizontal driving mechanism driving the horizontal slide 402 to slide horizontally, a cutting knife 404 sliding vertically on the horizontal slide 402, and a vertical driving mechanism driving the cutting knife 404 to move vertically, and the vertical driving mechanism is installed on the horizontal slide 402. The horizontal driving mechanism is preferably a linear reciprocating motion mechanism such as an electric cylinder 405 or a cylinder.

[0048] When cutting the formed raw materials, the formed raw materials move horizontally on the conveying mechanism, and the electric cylinder 405 drives the horizontal slide 402 to move horizontally, that is, the cutting knife 404 has horizontal movement. In the horizontal direction, the cutting knife 404 and the formed raw materials do not produce relative movement. At the same time, the vertical driving mechanism drives the cutting knife 404 to move vertically. The combined movement of the horizontal movement and the vertical movement of the cutting knife 404 cuts the formed raw materials into product 6, and the cutting surface is vertical.

[0049] The cutting knife 404 is mounted on a vertical slide, and the vertical slide slides vertically on a vertical guide rail 403, and the vertical guide rail 403 is fixed on a horizontal slide 402; the vertical driving mechanism includes a cutting knife motor 407, an eccentric disk 408 driven to rotate by the cutting knife motor 407, and a connecting rod 409 hingedly connected between the eccentric disk 408 and the vertical slide, and the cutting knife motor 407 is mounted on the horizontal slide 402, and the hinge point between the connecting rod 409 and the eccentric disk 408 deviates from the rotation center of the eccentric disk 408. When the cutting knife motor 407 drives the eccentric disk 408 to rotate, the eccentric disk 408 drives the vertical slide to move up and down through the connecting rod 409, and then drives the cutting knife 404 to move up and down to cut the product 6.

[0050] The vertical slide includes a fixedly connected traction frame 406 and a tool holder; the tool holder includes a fixed seat 410 for fixing the cutting knife 404, a horizontal support rod 411 fixed on the fixed seat 410 and at least two vertical support rods 412 fixed on the horizontal support rod 411, the vertical support rods 412 are arranged at intervals and connected to the cutting knife 404, the cutting knife 404 is preferably a long blade or a steel wire rope, and the vertical support rod 412 is used to increase the rigidity of the long blade or to keep the steel wire rope taut.

[0051] A horizontal adjustment slot 413 is provided on the horizontal support rod 411, and the position of the vertical support rod 412 in the adjustment slot 413 is adjustable to meet the use requirements of different long blades or wire ropes.

[0052] like Figure 2-Figure 5As shown together, the distributor 23 includes a shell 231 fixed on the frame 1, a stator 232 fixed in the shell 231 and a rotor 233 located in the stator 232 and adapted to the stator 232. The servo motor 24 drives all the rotors 2344 to rotate synchronously. Two cross-arranged blades 234 are provided on the rotor 233. The blades 234 can slide on the rotor 233. The two blades 234 are respectively provided with avoidance gaps to avoid motion interference. The distributor feed port 235 and the distributor discharge port 236 are respectively provided on the shell 231 and communicate with the inner cavity of the stator 232. In the illustrated embodiment, all the distributors 23 share one shell 231;

[0053] When the distributor 23 is working, the servo motor 24 drives the rotor 233 to move in the stator 232. The rotor 233 is tangent to the stator 232. The ends of the two blades 234 are always in contact with the inner surface of the stator 232. The rotor 233, the blades 234 and the stator 232 form a closed distribution cavity. Along the movement direction of the rotor 233, at the distributor feed port 235, the volume of the distribution cavity gradually increases, and the raw materials are continuously filled into the distribution cavity. At the distributor discharge port 236, the volume of the distribution cavity gradually decreases, and the raw materials in the distribution cavity are squeezed downward into the distributor discharge port 236 and output to the forming mold 3. If the pressure sensor 25 detects that the feed pressure is within the set standard range, the servo motor 24 drives all rotors 233 to rotate synchronously at the same angle, so that all distributors 23 synchronously output a portion of raw materials of the same weight as the product.

[0054] Furthermore, the position and movement of each rotor 233 are synchronized, and the position and movement of the corresponding blade 234 on each rotor 233 are synchronized, so that each distributor 23 can move synchronously. Accordingly, each molding mold 3 can obtain raw materials at the same time and release the product 6 to the conveying mechanism at the same time, thereby ensuring production consistency and improving production efficiency.

[0055] Each rotor 233 is connected by four rotor connecting rods 237, which penetrate all rotors 233 and connect all rotors 233 together, forcing each rotor 233 to have consistent position and movement. One end of the four rotor connecting rods 237 is respectively mounted on the transmission plate 239. The servo motor 24 drives the transmission plate 239 to rotate, thereby driving all rotors 233 to rotate synchronously. According to the pressure detected by the pressure sensor 25, the servo motor 24 adjusts the angle of rotation of the rotor 233 so that each distributor 23 can divide the portions consistently. Each stator 232 is connected by two stator connecting rods 238, which penetrate all stators 232, forcing each stator 232 to have consistent position.

[0056] like Figure 6 and Figure 7As shown together, the forming mold 3 includes a connecting block 31, a feed pipe 32, a bent joint 33 and a horizontal mold body 34. The connecting block 31 is fixedly connected to the housing 231. The feed pipe 32 and the mold body 34 correspond to each other. A bent joint 33 is provided between each corresponding feed pipe 32 and mold body 34. The feed pipes 32 and the material distributor outlet 236 are equal in number and are connected to each other. A card slot 35 is provided on the bent joint 33. The end of the mold body 34 is provided with a card connection portion with the card slot 35. The card connection portion is inserted into the card slot 35. The mold body 34 is installed on the bent joint 33. To produce different products 6, the corresponding mold body 34 is installed in the card slot 35. The mold body 34 is tubular, and the shape of its inner cavity determines the shape of the product 6. Its inner cavity can be designed into various shapes such as round, square, rectangular, petal-shaped, etc., to output solid or hollow products 6.

[0057] The conveying mechanism includes a horizontally arranged belt conveyor 5, the upper belt of the belt conveyor 5 is height-adjustable, thereby changing the height of the belt below the forming mold 3 to avoid excessive distance between the belt and the forming mold 3, which causes the product 6 to fall onto the belt and be broken and deformed, thereby ensuring the shape of the product 6.

[0058] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field.
