[0029] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] If the utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.) when describing, it is necessary to define the directions involved, such as "In order to clearly express the positions and directions described in the utility model, the end close to the operator is the proximal end, and the end away from the operator is the distal end." Or define it with the paper as a reference, etc. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, it does not need to be defined here.

[0031] A double-platform reciprocating feeding pressing device, such as Figure 1 As shown, it includes a support 2, on which a pressing assembly 3, a driving mechanism 4 and two feeding platforms 5 are arranged. The driving mechanism 4 is used to drive the two feeding platforms 5 to alternately perform reciprocating motion between the loading position and the pressing assembly 3. The feeding platforms 5 are used to load materials 100. The two feeding platforms 5 are arranged opposite to each other and have the same loading point and pressing point. A avoiding mechanism 6 is also arranged between the feeding platform 5 and the support 2. The motion trajectory of the feeding platform 5 includes a first conveying section, an avoiding section and a second conveying section connected in sequence. The first conveying sections of the two feeding platforms 5 overlap, the second conveying sections of the two feeding platforms 5 overlap, and the avoiding sections of the two feeding platforms 5 are away from each other. The avoiding mechanism 6 is used to make the two feeding platforms 5 avoid each other when they are about to meet during the reciprocating motion. Specifically, the position where the feeding platform 5 takes materials from the loading point is defined as the loading point, and the position where the feeding platform 5 reaches the pressing mechanism to unload materials is defined as the pressing point. In order to simplify the structure and process and save space and equipment, the two feeding platforms 5 have the same loading point and the same pressing point, that is, the same loading device and the same pressing component 3. When the size of the material 100 does not exceed the loading size of the feeding platform 5, the avoidance mechanism 6 needs to be set so that the two feeding platforms 5 will not collide during the reciprocating motion.

[0032] like Figure 2 As shown, the driving mechanism 4 includes a motor 41, a gear 42 and two racks 43. The motor 41 is arranged on the support 2. The motor 41 drives the gear 42 to rotate forward and reverse periodically. The two racks 43 are respectively arranged on both sides of the gear 42 and mesh with the gear 42. The two racks 43 are arranged in parallel. Each rack 43 is connected to a feeding platform 5. When the motor 41 drives the gear 42 to rotate forward or reverse, the two racks 43 will make linear motion in opposite directions. The two feeding platforms 5 make linear motion together with the racks 43 on the same side. The motor 41 continuously rotates forward and reverse, so that the two feeding platforms 5 make reciprocating motion.

[0033] As an embodiment of the utility model, a rack slideway 44 is provided on the support 2, and the rack slideway 44 is used for the rack 43 to slide therein, thereby saving space and making the overall structure more compact.

[0034] like Figure 3 As shown, a guiding mechanism is arranged on the support 2, and the guiding mechanism includes a first slide rail 7 and a first slider 8 matched with the first slide rail 7, the first slider 8 is connected to the feeding platform 5, the first slider 8 can slide on the first slide rail 7, the first slide rail 7 is arranged parallel to the rack 43, when the rack 43 drives the feeding platform 5 to make linear motion, the feeding platform 5 drives the first slider 8 to slide on the first slide rail 7, thereby playing a guiding and stabilizing role in the linear motion of the feeding platform 5.

[0035] like Figure 2 , 3 As shown, the avoidance mechanism 6 includes an avoidance slide 61, a rolling element, a rotating shaft 63 and a decoupling mechanism. The avoidance slide 61 is arranged on the support 2, and the rolling element can roll along the avoidance slide 61 in the avoidance slide 61. One end of the rotating shaft 63 is connected to the feeding platform 5, and the other end of the rotating shaft 63 is connected to the rolling element. The avoidance slide 61 includes a first linear portion 611, a yielding portion 612 and a second linear portion 613 connected end to end. The first linear portion 611 and the second linear portion 613 are located on the same straight line and are parallel to the rack 43. The yielding portion 612 is arranged away from the gear 42 relative to the straight line where the first linear portion 611 is located; the decoupling mechanism is arranged on the feeding platform 5, and the decoupling mechanism enables the feeding platform 5 to have the freedom to move away from or close to the rack 43, so that the feeding platform 5 can simultaneously meet the movement of the driving mechanism 4 and the avoidance mechanism 6. When the rolling element slides from the first linear portion 611 to the yielding portion 612 , the rolling element moves away from the gear 42 . When the rolling element slides from the yielding portion 612 to the second linear portion 613 , the rolling element moves toward the gear 42 .

[0036] As an embodiment of the present invention, the rolling element is a bearing 62 , and the rotating shaft 63 is rotatably disposed in the bearing 62 .

[0037] As an embodiment of the utility model, a rounded transition is adopted at the connection between the first linear portion 611 and the giving way portion 612, and a rounded transition is adopted at the connection between the giving way portion 612 and the second linear portion 613, so that the rolling element slides more smoothly when sliding from the first linear portion 611 into the giving way portion 612 and sliding from the giving way portion 612 into the second linear portion 613.

[0038] The decoupling mechanism includes a second slide rail 9 and a second slider 10 matched with the second slide rail 9, the second slide rail 9 is arranged on the rack 43, the second slide rail 9 and the rack 43 are arranged vertically, the second slider 10 is connected to the feeding platform 5, when the rotating shaft 63 drives the feeding platform 5 to do an evasive movement, the feeding platform 5 drives the second slider 10 to slide on the second slide rail 9 to decouple.

[0039] A connecting plate 11 is provided on the rack 43, the second slide rail 9 is provided on the connecting plate 11, and a clearance groove 12 is provided on the connecting plate 11. The clearance groove 12 is used to make way for the movement of the rotating shaft 63, so that the rotating shaft 63 has sufficient movement space under the compact structural design. Specifically, when the rolling element slides in the avoidance slideway 61 and moves toward or away from the gear 42, the rotating shaft 63 has space to move toward or away from the gear 42.

[0040] The pressing assembly 3 includes a pressing bracket 31 arranged on the support 2, a lifting mechanism 32 and a pressing head 33 driven by the lifting mechanism 32 to perform lifting motion are arranged on the pressing bracket 31, a weight 34 is arranged on the pressing head 33, and a pressing area 35 is also arranged on the pressing bracket 31, and the pressing area 35 is the pressing point. The lifting mechanism 32 can be driven by a cylinder.

[0041] The feeding platform 5 includes a platform body 51 and an oblique conveying arm 52 extending from the platform body 51 toward the pressing mechanism. The material 100 is arranged at the end of the conveying arm 52 away from the platform body 51, so that the material 100 can be conveyed farther in a shorter stroke.

[0042] As an embodiment of the utility model, the pressing zone 35 has a unidirectional feed port, which faces the feeding platform 5. The size of the end of the conveying arm 52 of the feeding platform 5 away from the platform body 51 is smaller than the opening size of the feed port. The end of the conveying arm 52 of the feeding platform 5 away from the platform body 51 cooperates with the pressing zone 35. When the rack 43 reaches the end of the feeding stroke, the end of the conveying arm 52 on the same side away from the platform body 51 enters the feed port and reaches the pressing zone 35, and the material 100 reaches the pressing point.

[0043] The working principle of the utility model is:

[0044] The two feeding platforms 5 are defined as a first feeding platform 5 and a second feeding platform 5, the direction from the feeding point to the pressing point is defined as an x ​​direction, and the direction perpendicular to the x direction and in the horizontal plane is defined as a y direction;

[0045] The material 100 is placed on the first feeding platform 5. When the motor 41 rotates forward, the first feeding platform 5 moves toward the pressing assembly 3, and the second feeding platform 5 moves toward the upper feeding point. Due to the action of the respective avoidance mechanisms 6 and decoupling mechanisms, when the first feeding platform 5 and the second feeding platform 5 approach each other in the x direction, the first feeding platform 5 and the second feeding platform 5 move away from each other in the y direction. Finally, the first feeding platform 5 reaches the pressing point, and the conveying arm 52 of the first feeding platform 5 enters the pressing area 35. The pressing head 33 descends to press the material 100.

[0046] When the second feeding platform 5 reaches the loading point, the material 100 is placed on the second feeding platform 5. At this time, the motor 41 reverses, the second feeding platform 5 moves toward the pressing component 3, and the first feeding platform 5 moves toward the upper feeding point. The rest is consistent with the above steps and is repeated.

[0047] The double-platform reciprocating feeding and pressing device provided by the utility model adopts the above structure, sets the gear 42 and the double-sided rack 43, utilizes the forward and reverse rotation of the motor 41 to realize the alternating reciprocating motion of the two feeding platforms 5, and adds the avoidance mechanism 6 to avoid the collision between the two feeding platforms 5 during the reciprocating motion. The structure is simple and compact, and the loading and unloading efficiency is improved.

[0048] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0049] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
