The first inclined guide groove, the second inclined guide groove, the first guide rail and the second guide rail cooperate to form a motion track for the slider to cyclically guide and slide.

[0005] When the material is pushed, the guide rod continues to move along the conveyor belt, and the slider enters the second inclined guide groove through the guidance of the first guide rail, and further drives the slider to slide on the guide rod through the second inclined guide groove, so that the push rod retracts, and further squeezes the elastic member through the extrusion member, so that the telescopic rod retracts, thereby driving the pressure plate to flip and retract, and further, the slider can enter the first inclined guide groove through the second guide rail to realize the reciprocating operation of the product.

DETAILED DESCRIPTION

[0019] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings: In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. The application of this product requires that the material and the carton move at the same speed as the conveyor belt, so that the material and the carton remain on one side of the push rod when the push rod moves forward. The specific material transportation and carton transportation are not the inventive point of the present invention, and will not be introduced in detail herein.

[0020] The present invention discloses a material pushing device, including an assembly frame 1, a push rod 2 and a driving mechanism 3 for driving the push rod 2 to push the material. In the implementation case of the present invention, the driving mechanism 3 includes a conveyor belt 31, a mounting frame 32, and a first inclined guide groove 33. The mounting frame 32 includes a guide rod 321 and a slider 322 slidably arranged on the guide rod 321. The guide rod 321 is connected to the conveyor belt 31 and moves synchronously with it (the conveyor belt 31 is most preferably provided with two groups and located on opposite sides of the guide rod 321). The push rod 2 is arranged on the slider 322, and the slider 322 is partially inserted into the first inclined guide groove 33. A pressing plate 4 is hingedly arranged on the push rod 2, and the push rod 2 also includes a connecting rod 51, a telescopic rod 52 and an elastic member 53 for driving the telescopic rod 52 to telescope relative to each other. The telescopic rod 52 is arranged on the slider 322 and can telescope relative to the push rod 2. One end of the connecting rod 51 is hingedly arranged on the telescopic rod 52. The elastic member 53 has one end which acts on the telescopic rod 52 and the other end which acts on the slider 322 or the push rod 2. The assembly frame 1 is provided with an extrusion member 54 which is located on the movement trajectory of the slider 322 and is used to limit the resetting of the elastic member 53. The assembly frame 1 is also provided with a second inclined guide groove 6 which is located below the first inclined guide groove 33. It also includes a first guide rail 7 and a second guide rail 8. One end of the first guide rail 7 is connected to the tail of the first inclined guide groove 33 and the other end is connected to the head of the second inclined guide groove 6. One end of the second guide rail 8 is connected to the tail of the second inclined guide groove 6 and the other end is connected to the head of the first inclined guide groove 33. The first inclined guide groove 33, the second inclined guide groove 6, the first guide rail 7 and the second guide rail 8 cooperate to form a motion track for the slider 322 to slide in a circular guide manner.

[0021] By adopting the above technical solution, when in use, the guide rod 321 is driven to move by the conveyor belt 31. When it moves to the specified position, the elastic member 53 will be separated from the extrusion of the extrusion member 54, so that the elastic member 53 is reset, and at the same time, the telescopic rod 52 is driven to extend relatively. At the same time, the telescopic rod 52 will also drive the connecting rod 51 to extend forward, thereby driving the pressing plate 4 to rotate, and the material can be pressed. At the same time, the slider is guided by the first inclined guide groove 33, so that the slide bar moves on the guide rod 321, thereby driving the push rod 2 to extend forward to achieve the pushing action, thereby achieving seamless connection, realizing the pressing and pushing effects, and the driving cost is relatively low. And it is not easy to make mistakes. After the material is pushed, the guide rod 321 continues to move along the conveyor belt 31, and the slider 322 enters the second inclined guide groove 6 through the guidance of the first guide rail 7, and further drives the slider 322 to slide on the guide rod 321 through the second inclined guide groove 6, so that the push rod 2 retracts, and further squeezes the elastic member 53 through the extrusion member 54, so that the telescopic rod 52 retracts, thereby driving the pressure plate 4 to flip and retract, thereby preventing the pressure plate 4 from colliding with the assembly frame 1, and further, the slider 322 can enter the first inclined guide groove 33 through the second guide rail 8 to realize the reciprocating operation of the product.

[0022] A retraction section 331 is disposed obliquely rearward at the tail end of the first inclined guide groove 33 . The retraction section 331 can drive the slider 322 to retract a certain distance, so as to prevent the push rod 2 from colliding with the assembly frame 1 when the slider 322 enters the first guide rail 7 .

[0023] The guide rods 321 are arranged in several groups at intervals along the conveyor belt 31, and each group of guide rods 321 is provided with a slider 322. There are also multiple groups of push rods 2 and elastic members 53. Multiple groups of push rods 2 can circulate at the same time, breaking the intermittent disadvantages of traditional pressing and pushing, so that it can continuously perform boxing work with higher efficiency.

[0024] The slider 322 is provided with a spring seat 91, and the elastic member 53 is a spring (the elastic member 53 can of course also be a spring sheet). The telescopic rod 52 slides and retracts on the spring seat 91, and the spring is sleeved on the telescopic rod 52, and also includes an abutment block 92 locked with the telescopic rod 52. One end of the spring abuts against the spring seat 91, and the other end abuts against the abutment block 92. The extrusion member 54 is a blocking rail arranged on one side of the abutment block 92. The head position of the blocking rail is most preferably also provided with an inclined or arc-shaped guiding surface. The blocking rail is located at the head position of the second inclined guide groove 6 and extends along the movement trajectory of the slider 322 to the head position of the first inclined guide groove 33. The spring seat 91 can facilitate the installation of the spring and the telescopic rod 52, and the spring can be driven to compress by squeezing the abutment block 92. The structure is simple and the layout is relatively reasonable. When the abutment block 92 abuts against the blocking rail, the blocking rail will squeeze the abutment block 92, so that the spring remains in a compressed state, thereby preventing the pressure plate 4 from flipping and pressing down.

[0025] The assembly frame 1 is also provided with an inclined guide member 10 at the head position of the first inclined guide groove 33 (the inclined guide member 10 is most preferably formed in one piece and fixedly arranged on the end of the blocking track, so as to have better stability). The inclined guide member 10 is connected with the end of the blocking track. The inclined guide member 10 cooperates with the abutment block 92 so that the elastic member 53 can be gradually reset, which can have a buffering effect, has better stability, and prevents damage.

[0026] Each group of guide rods 321 is provided with at least two, which can prevent the slider 322 from rotating on the guide rods 321, so that the slider 322 has better stability when the guide slides.

[0027] A U-shaped groove 921 is provided at the bottom of the abutment block 92, and a guide column 20 is provided on the spring seat 91 at a position corresponding to the U-shaped groove 921. The abutment block 92 can slide relative to the guide column 20 to prevent the abutment block 92 from relative displacement, making it more stable when in use.
