DETAILED DESCRIPTION

[0025] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the drawings in the embodiments of the present application.

[0026] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0028] Referring to Figures 1-5 The present application discloses a squeezing head assembly, comprising a squeezing swing arm 10 and a squeezing rod 20, one end of the squeezing swing arm 10 is formed into a rotatable end 11, and the other end of the squeezing swing arm 10 is formed into a force receiving end 12. A connecting arm 13 is arranged on the squeezing swing arm 10, and the connecting arm 13 is located between the rotatable end 11 and the force receiving end 12, and the force receiving end 12 can drive the rotatable end 11 to rotate when subjected to force.

[0029] In addition, one end of the squeezing rod 20 is formed into a connecting head 21, and the other end of the squeezing rod 20 is provided with a squeezing head 22, and the connecting head 21 is rotatably connected to the connecting arm 13 through a connecting piece, so that the squeezing rod 20 swings downward under the action of gravity.

[0030] On the basis of the above structure, when the pressing head assembly of the utility model is used, the rotatable end 11 of the pressing swing arm 10 can be rotatably connected to the base 30 when the pressing action is performed, the base 30 can be a device for a juicer, a dough machine or the like which needs to be extruded by the pressing head 22, and the force end 12 of the pressing swing arm 10 is forced, specifically, a hand can act on the pressing swing arm 10, that is, a manual pressing action is performed. Of course, a driving structure provided on the base 30, such as a driving cylinder, can be used to connect the piston rod of the driving cylinder to the force end 12 to drive the pressing swing arm 10 up and down to realize an automatic pressing action.

[0031] When the pressing action is performed, the material is placed in the pressing cup 40, the pressing rod 20 can be inserted into the pressing cup 40, and then the force end of the pressing swing arm 10 moves upward, because the pressing rod 20 is connected to the pressing swing arm 10 through the connecting piece, after the pressing swing arm 10 moves upward, the pressing rod 20 on the pressing swing arm 10 can be driven to move upward, thereafter, the pressing swing arm 10 moves downward to drive the pressing rod 20 on the pressing swing arm 10 to move downward, and the pressing head 22 on the pressing rod 20 can press the material in the pressing cup 40 after moving downward, so that the pressing head 22 of the pressing rod 20 can realize pressing during the up-and-down swinging of the pressing swing arm 10.

[0032] For example, the fruit and vegetable materials needed for juicing are placed in the pressing cup 40, and the fruit and vegetable materials can be pressed during the up-and-down movement of the pressing head 22 of the pressing rod 20 until the fruit and vegetable juice is obtained. For another example, when the dough and the like are placed in the pressing cup 40 to be compacted by pressure, the pressing head 22 of the pressing rod 20 can be moved up and down to continuously compact the dough until the compacting action of the dough is completed.

[0033] It should be noted that in the embodiment, because the pressing rod 20 is rotatably connected to the connecting arm 13 of the pressing swing arm 10 through the connecting head 21 and the connecting piece, and the pressing rod 20 and the pressing head 22 both have a certain weight, when the pressing swing arm 10 moves upward, the downward gravity of the pressing rod 20 and the pressing head 22 can act on themselves, so that the pressing rod 20 can swing downward to the vertical state relative to the pressing rod 20 when the pressing swing arm 10 moves upward, so that the pressing rod 20 is in the vertical state during the up-and-down movement of the pressing swing arm 10 to act on the material in the pressing cup 40.

[0034] If the pressing rod 20 adopts the connection mode in the prior art and is fixedly connected with the pressing swing arm 10, the pressing rod 20 will also swing upward by a certain angle in the process that the pressing swing arm 10 swings upward, which will collide with the cup body of the pressing cup 40 in the process of swinging, and the pressing cup 40 is prone to tilting. In order to prevent the collision with the cup in the pressing process, the swinging range of the pressing swing arm 10 must be controlled in a small range, so that the height of the pressing rod 20 being lifted is limited, the pressure applied to the material is small, and the pressing efficiency is low.

[0035] Therefore, in the embodiment, the pressing rod 20 and the pressing head 22 can swing downward to a vertical state in the process that the pressing swing arm 10 swings upward, so that the pressing swing arm 10 will not collide with the cup even if it swings upward by a large angle, and can be lifted upward by a large range, so that the pressure applied to the material is large when pressing downward, and the pressing efficiency can be improved.

[0036] In addition, it should be noted that the vertical state in the embodiment refers to a state that the pressing head 22 can be kept downward under the action of gravity, and is not absolutely vertical, but can be a small angle of deflection from the vertical direction, but the angle of deflection is subject to the condition that the collision with the cup does not occur in the pressing process. In order to keep this state, a counterweight can be additionally arranged on the pressing rod 20, or the pressing head 22 itself can adopt a pressing head 22 with large mass to keep the state of gravity downward, which can be selected and arranged according to actual needs.

[0037] Of course, the pressing head in the embodiment can be a conical head integrally formed at the bottom end of the pressing rod, so that the conical surface and the outer surface of the pressing rod are connected and transitioned, and the pressing head is not prone to breaking in the pressing process, and the surface of the pressing head is conical, so that the material is not prone to accumulation. In addition, the pressing head can also have a ball head structure or other structure with an outer diameter protruding from the outer diameter of the pressing rod, and the connection mode of the pressing head can also adopt a bolt connection structure, but compared with the integrally formed structure in the embodiment, there is a risk of falling, so the integrally formed pressing head structure is preferred in the embodiment.

[0038] Further, the connecting piece includes a rotating shaft, and the connecting head 21 is rotatably connected to the connecting arm 13 through the rotating shaft. In assembly, one end of the rotating shaft is connected to the connecting arm 13 and rotatably connected with the connecting arm 13, and the other end of the rotating shaft is connected to the connecting head 21, so as to realize the rotary connection of the pressing rod 20 and the pressing swing arm 10.

[0039] It should be noted that the rotating shaft can be selected as a connecting pin in the prior art, and the connecting pin is used for rotatable connection, so that the rotation between the connecting head 21 and the connecting arm 13 has a certain damping force, and the gravity of the pressing rod 20 and the pressing head 22 can overcome the rotation damping force to swing downward to the vertical state; and if the swinging between the connecting head 21 and the connecting arm 13 is too flexible, the cup is easily knocked over due to random swinging under the action of external force, so the connecting pin is used for rotatable connection, and the damping force provided can reduce the flexible swinging between the connecting head 21 and the connecting arm 13, and reduce the cup knocking over due to excessive downward swinging of the pressing rod 20.

[0040] Of course, the connecting piece can also be a screw rod penetrating the connecting arm 13 and the connecting head 21, and the screw rod is assembled by connecting nuts at both ends. The structure of the connecting piece can be selected and arranged according to actual needs.

[0041] More specifically, the connecting arm 13 is provided with a first connecting piece 131, and the connecting head 21 is provided with a second connecting piece 214. During assembly, the first connecting piece 131 and the second connecting piece 214 are rotatably connected by a rotating shaft. Specifically, two first connecting pieces 131 can be provided on the connecting arm 13, and the second connecting piece 214 can be inserted between the two first connecting pieces 131, and then a rotating shaft is penetrated to realize rotatable connection, so that the rotating structure is more stable.

[0042] Further, the connecting head 21 and the pressing rod 20 are detachably connected, so that before the pressing action starts, the pressing rod 20 can be detached from the connecting head 21, and during the pressing action, the pressing rod 20 can be placed into the pressing cup 40 outside the machine body, and then the pressing cup 40 is placed under the pressing swing arm 10, and the connecting head 21 at the top end of the pressing rod 20 is assembled with the connecting arm 13 to start the pressing action.

[0043] If the connecting head 21 and the pressing rod 20 are not detachably connected, the pressing swing arm 10 is lifted to a high state when the pressing cup 40 is taken out or placed in, or the pressing cup 40 is placed in or taken out at a certain angle, so that the operation is not convenient, and material spilling is easy to occur.

[0044] With the structure of the present application, after the pressing action is completed, the connecting arm 13 of the pressing swing arm 10 can be detached from the pressing rod 20, and the pressing cup 40 can be taken out together with the pressing rod 20, so that the pressing rod 20 can be cleaned separately outside the machine body, and the state of the pressing swing arm 10 does not interfere with the taking out of the pressing rod 20.

[0045] Specifically, in order to facilitate connection, the connecting head 21 can be provided with a clamping groove 211, and a clamping head 23 is arranged at the top end of the pressing rod 20, and the clamping head 23 is clamped into the clamping groove 211, so that the detachable connection of the pressing rod 20 and the connecting arm 13 can be achieved by clamping.

[0046] Of course, in addition to the detachable connection of the connecting head 21 and the connecting arm 13, the clamping connection mode in the embodiment can also be selected as a threaded connection mode, such as providing a threaded connecting head 21 on the pressing rod 20, and a threaded connecting groove is arranged on the connecting arm 13, so that the detachable connection can also be achieved, but the threaded machining precision is required to be high, and the threaded connection needs to be rotated during disassembly and assembly, and the disassembly and assembly process is not convenient. Alternatively, a spring pin is arranged on the connecting arm 13, and a spring pin hole is arranged on the pressing rod 20, so that the detachable connection can be achieved by clamping or withdrawing the spring pin, but this needs to press the spring pin for operation, and the disassembly process is not convenient, so the clamping mode of the clamping head 23 and the clamping groove 211 is selected for disassembly in the embodiment, which is convenient for machining and can achieve quick disassembly and assembly.

[0047] Further, the clamping head 23 is arranged on the side of the connecting head 21 and penetrates the clamping groove 211, and the clamping steps 212 are arranged on the two side walls of the clamping groove 211. The outer diameter of the clamping head 23 protrudes from the outer diameter of the top end of the pressing rod 20. Since the clamping head 23 protrudes from the outer surface of the pressing rod 20, that is, the clamping head 23 and the pressing rod 20 can form a clamping recess position.

[0048] When the pressing rod 20 and the connecting head 21 are assembled, the clamping head 23 of the pressing rod 20 can be clamped into the clamping groove 211 through the clamping opening, and when the clamping head 23 is clamped into the clamping groove 211, the clamping recess position between the clamping head 23 and the pressing rod 20 is clamped into the clamping step 212, so that after the clamping is in place, the clamping step 212 and the clamping recess position are limited, and the disconnection during the pressing process is reduced. When the pressing rod 20 is disassembled, the clamping head 23 can be separated from the clamping groove 211 through the clamping opening, which is convenient for disassembly and assembly.

[0049] More specifically, a guide slope 213 is arranged at the clamping opening, which is inclined upward from outside to inside and connected with the clamping step 212. If the clamping step 212 extends directly to the clamping position, the clamping recess formed between the clamping head 23 and the end of the pressing rod 20 needs to be aligned with the clamping step 212 when the clamping head 23 is clamped into the clamping slot 211, which can be smoothly clamped, but the alignment accuracy of the assembly process is relatively high. Therefore, in the embodiment, the guide slope 213 is arranged at the clamping position, and when the clamping head 23 is clamped into the clamping slot 211, the clamping head 23 corresponds to the clamping opening position, and the clamping head 23 is clamped into the clamping slot 211 along the guide slope 213. In the gradual clamping process, the clamping head 23 is clamped upward and inward along the guide slope 213, so that the clamping process is smooth and the assembly difficulty is reduced.

[0050] Of course, since the guide slope 213 can guide the clamping head 23 to clamp upward and inward during the clamping process, it is not easy to disengage after clamping into the clamping slot 211.

[0051] More specifically, the outer surface of the clamping head 23 in the embodiment can also be a circular arc surface. First, the clamping head 23 adopts a circular arc surface as the outer surface, that is, adopts a spherical head structure, which can better form a clamping recess at the top end of the pressing head 22. At the same time, the circular arc surface can be in sliding cooperation with the guide slope 213, and the clamping process of the clamping head 23 is more smooth.

[0052] In other cases, in order to form a clamping recess at the top end of the pressing rod 20, the clamping head 23 can also be connected with the pressing rod 20 at a slope, and a clamping recess can also be formed. In addition, a recess structure can also be directly machined at the connection position of the clamping head 23 and the pressing rod 20, so that clamping limiting can also be achieved. However, directly machining a recess connection can cause a risk of fracture at the connection position of the clamping head 23 and the pressing rod 20. Therefore, the embodiment adopts a circular arc surface connection to reduce the risk of fracture.

[0054] A kind of press, including base 30 and the press head assembly in embodiment 1;Rotatable end 11 of press swing arm 10 can be rotatably connected on base 30.When using the press of the utility model, material is placed in press cup 40, press bar 20 can be extended into press cup 40, then the force section of press swing arm 10 moves upward, since press bar 20 is connected to press swing arm 10 by connecting piece, after press swing arm 10 moves upward, it can drive press bar 20 on press swing arm 10 to move upward, then press swing arm 10 moves downward, drive press bar 20 on press swing arm 10 to move downward, press head 22 on press bar 20 can press the material in press cup 40 after moving downward, so that in the process of press swing arm 10 swinging up and down, press head 22 of press bar 20 realizes pressing.

[0055] It needs to be explained that, in the embodiment, since press bar 20 is rotatably connected to connecting arm 13 of press swing arm 10 by connecting head 21 through connecting piece, since press bar 20 and press head 22 both have certain weight, when press swing arm 10 moves upward, the downward gravity of press bar 20 and press head 22 can act on itself, so that press bar 20 can swing downward to vertical state relative to press bar 20 when press swing arm 10 moves upward, so that press bar 20 acts on the material in press cup 40 in vertical state in the process of press swing arm 10 moving up and down.

[0056] If press bar 20 adopts the connecting mode in prior art, and press swing arm 10 adopts fixed connection mode, so that press bar 20 also swings upward by certain angle in the process of press swing arm 10 swinging upward, so that it can touch cup body of press cup 40 in the process of swinging, and the situation of press cup 40 falling down is prone to occur.

[0057] Therefore, in the embodiment, press bar 20 and press head 22 can swing downward to vertical state relative in the process of press swing arm 10 swinging upward, so that press swing arm 10 does not touch cup even if it swings upward by large angle, and it can be lifted upward by large amplitude, so that the pressure on material is also large when pressing downward, so that the pressing efficiency can be improved.

[0058] In addition, it needs to be explained that the vertical state in the embodiment refers to the state that the pressing head 22 can be kept downward under the action of gravity, not the absolute vertical state, and can be a small angle deviation from the vertical direction.

[0059] Further, the top end of the base 30 is provided with a rotating seat 31, and the rotatable end 11 is rotatably connected to the rotating seat 31.

[0060] Specifically, the elastic component 14 can be selected as a spring in the prior art, and a connecting rod can be arranged on the rotating seat 31, one end of the spring is connected to the connecting rod of the rotating seat 31, and the other end of the spring can be connected to the top end position of the connecting arm 13 of the pressing swing arm 10 through a connecting bolt, so that the force point of the spring is located at the position of the connecting arm 13, so that the elastic stress acts on the position above the connecting arm 13 when the pressing swing arm 10 swings downward, and the force is applied to the corresponding position of the pressing rod 20, so that the effect is better.
