A switch one for controlling the opening of the cylinder is provided on the material barrel, and the first motor is controlled to start through the closing of the cylinder. A switch two for independently controlling the first motor is provided on the material barrel.

[0007] Preferably, an arc-shaped member in contact with the extrusion member is rotatably connected to the paddle. The arc-shaped member and the paddle are magnetically adsorbed. Magnetic blocks that are magnetically repulsive to the arc-shaped member and push the arc-shaped member to fit with the extrusion member are provided on the stirring member and the expansion plate, and there is a deviation in the front and rear positions between the arc-shaped member and the extrusion member.

[0008] Preferably, a first pusher and a second pusher are respectively provided on both sides of the stirring member. The position of the first pusher is lower than that of the second pusher, and the first pusher and the second pusher are attached to the stirring member. The first pusher and the second pusher are rotatably connected to the stirring member. Gear wheels three are provided on both the first pusher and the second pusher.

[0009] Preferably, a groove for accommodating the support shaft to pass through is provided on the expansion plate.

A closing plate for closing the groove after the expansion plate slides outwards is slidably connected to the stirring member.

[0010] Preferably, blades are provided on the stirring member and the expansion plate at the contact position of the arc-shaped member. An outlet for accommodating the discharge of the material is provided at the bottom of the blade. The side of the blade facing the arc-shaped member is the suction port, and an isolating member for blocking the arc-shaped member from being embedded in the blade is provided at the suction port of the blade. The blades are arranged at intervals.

[0011] Compared with the prior art, the beneficial effects of the present invention are: First, after using this device, the expansion board is driven to open by the adjustment component. When the rotating part is driven to rotate, the stirring part rotates synchronously and can drive the expansion board to rotate as well. As a result, the surface in contact with the material increases from the size of the stirring part to the size of the stirring part plus the expansion board, the amplitude of driving the stirred material increases, and the area covered by stirring increases, making the glue or material flow more evenly. Thus, the stirring effect is improved. After closing the adjustment component, when the first motor is turned on, the stirring part drives the expansion board to rotate self - sufficiently. When the rotating part drives the stirring part to rotate, the stirring part can also rotate self - sufficiently, thereby driving the paddles, the first pusher, and the second pusher to rotate and stir the material. Therefore, the stirring efficiency can be improved under high - speed rotation, and at the same time, it can be better switched between different stirring states according to different situations; Second, when the expansion board is embedded in the stirring part, it drives the rack to move upward and pushes the third gear, causing the first pusher to unfold. Also, the abutting block drives the fixing part to rotate, causing the second pusher to unfold as well. In this way, the same effect as a stirring impeller is formed with the upper and lower paddles and the two pushers. After the stirring part rotates and the expansion board rotates synchronously, at the same time, the first pusher and the second pusher rotate to stir the material. When the stirring part rotates, the first gear rotates synchronously and drives the second gear to rotate. The second gear drives the push block to move along the guiding groove of the connecting part, driving the connecting part to rotate. The connecting part drives the fixedly connected paddle to rotate along the rotation point, causing the paddle to approach the stirring part and the expansion board, and squeezing the material towards the stirring part and the expansion board. Thus, the material can be squeezed, and if there are bubbles in the material, the bubbles can be squeezed out; Third, after the second gear rotates, it drives the convex block to rotate synchronously. The convex block rotates from the position close to the paddle to the end far from the paddle. At the same time, it pulls the connecting rope to drive the squeezing part to move downward and approach the paddle. Also, the arc - shaped part stirs the stirring part and the expansion board. The arc - shaped part first abuts against the stirring part and the expansion board. After the squeezing part continues to move downward and abuts against the arc - shaped part, the material between the arc - shaped part and the squeezing part is squeezed, thereby achieving the effect of squeezing the material. Thus, when the stirring part and the expansion board revolve along the rotating part to push the material for stirring, and when the first motor drives the stirring part and the expansion board to rotate self - sufficiently, the rotation makes the pushed material generate a more complex flow state, promoting the mixing of raw materials at different positions. At the same time, the self - rotation can break up material lumps and bubbles, thereby improving the stirring efficiency and having better practicability compared with the prior art.

Detailed implementation manners

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is 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 orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] A hot melt adhesive raw material stirring and mixing device, as Figures 1-7As shown in the figure, it includes a material bucket 1 for placing materials, and a rotating member 2 rotatably connected to the material bucket 1. A number of stirring members 3 are connected to the rotating member 2. When using such equipment normally, the switch of the machine body or the material bucket 1 is turned on. After the materials are poured into the material bucket 1, the rotating member 2 inside rotates, and synchronously drives the stirring members 3 to rotate and stir the materials. After long-term rotation, the materials are mixed, and finally, after the stirring is completed, the materials are discharged from the outlet of the machine body. In this state, the stirring effect is single. However, an expansion plate 4 for increasing the contact surface with the materials is slidably connected inside the stirring member 3, and an adjustment assembly for adjusting the expansion plate 4 is provided on the stirring member 3. Paddles 5 for pushing the materials are rotatably connected to the stirring member 3 and the expansion plate 4 respectively, and the paddles 5 face in opposite directions. The stirring member 3 is rotatably connected to the rotating member 2, and a first motor 6 for controlling the rotation of the stirring member 3 is provided inside the rotating member 2. A connecting member 7 is provided at the rotating connection of the paddle 5 with the stirring member 3 and the expansion plate 4, and the connecting member 7 is fixedly connected to the paddle 5. The connecting member 7 is inclined. A support shaft 8 engaged with the stirring member 3 is provided on the first motor 6, and a first gear 9 is engaged with the support shaft 8. Second gears 10 engaged with the first gear 9 are provided on the stirring member 3 and the expansion plate 4, and a push block 11 is fixedly provided on the second gear 10. A guiding groove 12 for accommodating the push block 11 to be inserted is provided on the connecting member 7, and the connecting member 7 is driven to rotate through the push block 11 and the guiding groove 12. An extrusion assembly for extruding the materials and reducing the air bubbles inside the materials is provided on the paddle 5. After using this device, in the normal state, the stirring member 3 is driven to rotate by the rotating member 2 to continuously stir the materials. At the same time, the first motor 6 is turned on so that the stirring member 3 is driven to rotate along the support shaft 8 of the first motor 6. At the same time, when the stirring member 3 rotates, it will drive the internal expansion plate 4 to rotate together. In this state, when the stirring member 3 revolves around the rotating member 2, it can also be driven to rotate by itself by the first motor 6. When rotating by itself, the support shaft 8 and the first gear 9 rotate synchronously, and drive the engaged second gears 10 to rotate. While the second gears 10 are rotating, they will drive the push block 11 to rotate and push the connecting member 7 along the guiding groove 12 of the connecting member 7. Since the other end of the connecting member 7 is fixedly connected to the paddle 5, and the upper and lower parts are also rotatably connected to the stirring member 3 and the expansion plate 4 respectively, the connecting member 7 will drive the paddle 5 to swing under the push of the push block 11. Thus, when the stirring member 3 and the expansion plate 4 rotate by themselves to stir the materials, the paddle 5 also rotates to stir the materials when being driven to rotate, and continuously swings to contact the materials, increasing the fluidity and diversity of the flow of the materials, making the materials better mixed, thereby improving the stirring efficiency and making different raw materials more fully mixed.

[0016] The extrusion assembly includes an extrusion piece 13 rotatably connected to the paddle 5. A convex block 14 is provided on the side of the second gear 10 opposite to the push block 11. A connecting rope 15 is provided between the convex block 14 and the extrusion piece 13, and the convex block 14 is located at one end of the second gear 10 close to the paddle 5. A first clockwork spring 16 for pushing the extrusion piece 13 to reset is provided between the extrusion piece 13 and the paddle 5. The elastic force of the first clockwork spring 16 is greater than the force of the material in contact with the extrusion piece 13. A baffle 17 for blocking the backward rotation of the extrusion piece 13 is provided on the paddle 5. At the same time, when the paddle 5 is driven to swing, the extrusion piece 13 will also be driven to swing synchronously. While the second gear 10 rotates, the convex block 14 will also be driven to rotate. The convex block 14 rotates from a position close to the paddle 5 to the end of the second gear 10 farthest from the paddle 5, thereby pulling the connected connecting rope 15. Since the convex block 14 does not rotate itself, the connecting rope 15 will not be wound up. At the same time, after the connecting rope 15 is pulled downward, the extrusion piece 13 will be driven to rotate downward along the upper end of the paddle 5 to compress the first clockwork spring 16, so that the upper and lower extrusion pieces 13 approach the stirring piece 3 and the expansion plate 4. An arc-shaped piece 21 rotatably connected to the paddle 5 and abutting against the extrusion piece 13 is provided on the paddle 5. The arc-shaped piece 21 and the paddle 5 are magnetically adsorbed. Magnetic blocks 22 that are magnetically repulsive to the arc-shaped piece 21 and push the arc-shaped piece 21 to fit against the extrusion piece 13 are provided on the stirring piece 3 and the expansion plate 4. And there is a deviation in the front and rear positions between the arc-shaped piece 21 and the extrusion piece 13. When the paddle 5 swings close to the stirring piece 3 and the expansion plate 4, the arc-shaped pieces 21 on the upper and lower paddles 5 will respectively abut against the stirring piece 3 and the expansion plate 4. And when the extrusion piece 13 is pulled by the connecting rope 15 in this state, the arc-shaped piece 21 will abut against the extrusion piece 13, and at the same time, the material in contact between them will be extruded, so as to achieve the extrusion of the material and eliminate the bubbles on the extruded material. When the paddle 5 is driven to stir the material in the above state, the extrusion piece 13 and the arc-shaped piece 21 will also extrude the material. In various different states, the material is stirred more fully and the fluidity is also diverse, and better mixing can thus improve the mixing effect.

[0017] Secondly, after the push block 11 and the convex block 14 rotate and reset, the connecting piece 7 will be pulled to reset. At the same time, the clockwork spring in the paddle 5 will also drive the paddle 5, the extrusion piece 13 and the arc-shaped piece 21 to reset. And the elastic force of the first clockwork spring 16 in the extrusion piece 13 will also help the extrusion piece 13 to reset and re-abut against the baffle 17 to avoid the situation of excessive backward movement. And the elastic force of the clockwork spring in the arc-shaped piece 21 is greater than the magnetic force and less than the pushing force. In this way, it can be ensured that the arc-shaped piece 21 rotates when pushed by the stirring piece 3 and the expansion plate 4, and is driven by the clockwork spring to reset, while the elastic force of the clockwork spring during stirring can play a role in positioning and limiting. Such a setting can ensure that during the rotation of the stirring piece 3, the paddle 5, the arc-shaped piece 21 and the extrusion piece 13 can reciprocally swing and clamp.

[0018] The adjusting assembly includes a cylinder 18 fixedly arranged inside the stirring member 3. The extension plate 4 is provided with a groove for accommodating the embedding of the cylinder 18. The piston of the cylinder 18 is fixedly connected to the extension plate 4. A switch one 19 for controlling the opening of the cylinder 18 is provided on the material bucket 1, and the first motor 6 is controlled to start by closing the cylinder 18. A switch two 20 for independently controlling the first motor 6 is provided on the material bucket 1. By turning on the switch one 19 of the cylinder 18, the cylinder 18 drives the piston to move downward, and the piston is connected to the extension plate 4, thereby pushing the extension plate 4 downward. The extension plate 4 is provided with a groove 30 for the support shaft 8 to pass through. The stirring member 3 is provided with a sliding groove 31 for the shaft of the second gear 10 on the extension plate 4 to move. A closing plate 32 for closing the groove 30 when the extension slides outwards is slidably connected to the stirring member 3. At the same time, the groove 30 of the extension plate 4 also moves downward to avoid the situation where it is restricted by the support shaft 8 and cannot move downward. At the same time, after the extension plate 4 moves out of the stirring member 3, if the rotating member 2 drives the stirring member 3 and the extension plate 4 to rotate, the contact area between the original stirring member 3 and the material can be increased. Although the power consumption is relatively large under the same motor when the area for pushing the material is enlarged, the increased coverage area will make the flow more uniform, and the local concentration difference is reduced. When moving downward, the shaft of the second gear 10 on the extension plate 4 will move downward along the sliding groove 31 of the stirring member 3. At the same time, after being separated from the support of the shaft of the second gear 10, the closing plate 32 will also move downward to block the groove 30 where the extension plate 4 extends, so as to prevent the material from flowing in. At the same time, during the stirring process, if it is necessary to adjust, after closing the cylinder 18 and resetting the piston, the first motor 6 will also automatically start to switch the stirring state, so as to freely adjust to better adapt to the stirring effect required in different states. The control relationship between the first motor 6 and the cylinder 18 is prior art and will not be elaborated here.

[0019] On both sides of the stirring member 3, there are respectively a first pusher 24 and a second pusher 23. The position of the first pusher 24 is lower than that of the second pusher 23, and the first pusher 24 and the second pusher 23 are attached to the stirring member 3. The first pusher 24 and the second pusher 23 are rotatably connected to the stirring member 3. Both the first pusher 24 and the second pusher 23 are provided with a third gear 25. On the extension plate 4, there is a rack 26 that pushes the first pusher 24 to unfold and meshes with the third gear 25. On the stirring member 3, there is a fixing member 27. On the extension plate 4, there is an abutting block 28 that pushes the fixing member 27 to drive the second pusher 23 to rotate. Between the second pusher 23 and the stirring member 3, there is a second hairspring 29. When the air cylinder 18 moves upward to drive the extension plate 4 to reset, the rack 26 first moves upward to mesh with the third gear 25 and drives the third gear 25 to rotate. Through the third gear 25, the first pusher 24 is driven to rotate and unfold, rotating from the state of being attached to the stirring member 3 to being away from the stirring member 3. After the rotation and unfolding, the internal hairspring plays a role in supporting the first pusher 24. When the extension plate 4 continues to move upward and resets, the bottom abutting block 28 will abut against the fixing member 27 on the second pusher 23 and push the fixing member 27 to rotate. At the same time, the fixing member 27 drives the second pusher 23 to unfold. There are teeth near the fixing member 27 close to the second pusher 23, and there is also a third gear 25 on the second pusher 23. In this way, the rotation of the teeth of the fixing member 27 drives the third gear 25 of the second pusher 23 to rotate. The fixing member 27 with teeth meshes with the third gear 25 of the second pusher 23, which is equivalent to the transmission of two gears, and can change the rotation direction of the third gear 25 of the second pusher 23 to ensure that the second pusher 23 can also unfold. Thus, both the second pusher 23 and the first pusher 24 are unfolded, and form an effect similar to an impeller with the two paddle 5 pressing members 13. When rotating, it can continuously stir the material, and the second hairspring 29 can also play a supporting role. When the extension plate 4 unfolds, if the first pusher 24 and the second pusher 23 are in a horizontal state, the effect is not great, and it is also easy to accumulate materials. Through the drive of the rack 26 and the push of the second hairspring 29, the first pusher 24 and the second pusher 23 can be reset to ensure the effect of repeated use.

[0020] The stirring member 3 and the extension plate 4 are provided with blades 33 at the abutting positions of the arc-shaped member 21. The bottom of the blade 33 is provided with an outlet for discharging materials. The side of the blade 33 facing the arc-shaped member 21 is the suction inlet. And an isolating member 34 for preventing the arc-shaped member 21 from being embedded in the blade 33 is provided at the suction inlet of the blade 33. The blades 33 are arranged at intervals. Secondly, when the pressing member 13 is close to and the arc-shaped member 21 is in contact and pressed against the pressing member 13, the materials discharged to both sides can enter along the suction inlet of the blade 33 and be discharged along the outlet at the same time. In this way, the materials have a new flow direction. And through the continuous rotation of the blade 33, the blade 33 can suck in the materials to pressurize the pressing member 13 and the arc-shaped member 21, and then discharge them, thereby increasing the flow in different states and enhancing the mixing effect. The isolating member 34 can ensure that the arc-shaped member 21 and the pressing member 13 will not be embedded in the blade 33, resulting in a jamming situation.
