Description

Technical Field

[0001] The utility model belongs to the technical field of artificial board production equipment, and in particular relates to an automatic continuous putty extruder which can be used for supplying putty to artificial boards. Background Art

[0002] After the existing artificial boards are spliced, there will be a splicing seam between the two adjacent boards. In addition, since each tree will inevitably have loose knots or scars during its growth process, the cut boards may have many pits on them, which are usually called dead knots. At this time, in order to ensure that the formed boards can meet the actual aesthetic requirements, putty needs to be applied to the splicing seams and depressions.

[0003] The earliest traditional method is to manually dig out the mixed putty and then apply it manually. The accuracy of the putty application is uncontrollable and the application efficiency is low.

[0004] With the continuous development, there are automatic putty extrusion devices that can automatically extrude putty. For example, the patent with application number 892073098 and patent name proposes an electronic putty applicator and discloses a putty extrusion device. The putty extrusion device is a screw-propelled extrusion device, which mainly drives the screw to rotate by the rotation of the motor, so as to push the putty arranged in the putty extrusion tube outward through the screw. The putty extrusion device of this structure provides a force to push the putty through the motor. Since the putty is relatively viscous and has low fluidity, the motor needs to push with a large force, and when a large amount of putty coating operations need to be performed, the motor needs to provide a greater thrust. At this time, it is necessary to increase the feed and model of the motor, resulting in increased costs. In addition, the use of motor push is also very easy to cause the motor to be overloaded and damaged due to excessive putty load, and the reliability and stability are poor.

[0005] In addition, since the putty is pushed by a screw, the screw has a spiral structure, and the putty is easy to solidify after use. After long-term use, a large amount of putty will be stuck on the screw, affecting the flow rate of putty extrusion, and it is not easy to clean. After long-term use, the screw will be stuck, making it unusable;

[0006] The screw putty extruder still needs manual filling when feeding the putty, which leads to low putty extrusion efficiency and cannot realize continuous extrusion of putty. Utility Model Content

[0039] The utility model provides an embodiment of a putty automatic continuous extrusion device, referring to Figure 1-Figure 3 As shown, including:

[0040] Hopper 100;

[0041] The hopper 100, in some preferred embodiments, is structured as a conical hopper 100, and its corresponding inner diameter gradually decreases from top to bottom.

[0042] By setting the hopper 100 to be conical with a gradually decreasing inner diameter, when the material is put into the hopper 100, the inner side of the cone will have a guiding effect, so that the material can flow downward along the inner wall of the conical hopper 100 more quickly and smoothly, thereby speeding up the feeding speed.

[0043] The putty feeding seat 200 is connected to the hopper 100, and a putty supply channel 400 is formed between the putty feeding seat 200 and the hopper 100;

[0044] The putty material in the hopper 100 can flow into the putty feeding seat 200 through the putty supply channel 400 .

[0045] A greasy discharge channel 210 is formed in the greasy feeding seat 200. The greasy discharge channel 210 has a greasy discharge opening 211. The greasy discharge channel 210 is connected to the greasy supply channel 400.

[0046] The putty that needs to flow out can flow out from the putty outlet 211 through the putty outlet channel 210 .

[0047] A flow control component 300, connected to the fluid supply channel 400, for controlling the flow of the fluid supply channel 400;

[0048] The flow control component 300 can use an existing flow control valve, which is connected to the grease supply channel 400. When grease supply is not required, the flow control component 300 can be opened to the minimum, that is, zero opening, and the grease supply channel 400 is closed.

[0049] When grease supply is needed, it can be controlled to open to a preset opening as needed, thereby controlling the flow through the grease supply channel 400.

[0050] A material storage device 500 is connected to the putty feeding seat 200, and a material storage cavity 510 is formed inside the material storage device 500, and the material storage cavity 510 is communicated with the putty outlet channel 210;

[0051] The accumulator 500 is a storage cylinder for storing putty material, and its axis is colinear with the axis of the putty outlet channel 210 .

[0052] The putty pusher 600 is arranged in the material storage container 500 and is slidably and sealingly connected to the material storage container 500;

[0053] The driving device 700 includes a piston member 710, which is connected to the putty pushing member 600 and can drive the putty pushing member 600 to push the putty in the storage container 500 out through the putty outlet channel 210;

[0054] The piston member 710 of the driving device 700 can drive the putty pushing member 600 to move, thereby applying pressure to the putty pushing member 600 to drive the putty pushing member 600 to move, and push the putty in the storage container 500 out through the putty outlet channel 210.

[0055] In this embodiment, the putty pushing member 600 and the material storage container 500 are arranged to be connected in a sliding sealed manner mainly to ensure that the putty pushing member 600 can slide relative to the material storage container 500 and can generate pressure to the putty material in the material storage container 500 to squeeze it out when sliding.

[0056] The first position sensing element 810 is arranged at one end of the driving device 700 away from the putty feeding seat;

[0057] The second position sensing element 820 is arranged at one end of the driving device 700 close to the putty feeding seat;

[0058] In some embodiments of the present application, the driving device 700 is a driving cylinder, the piston member 710 is a pneumatic piston, the greasy pushing member 600 is a greasy pushing piston, which is arranged in the storage container 500, and the pneumatic piston and the greasy pushing piston are fixedly connected by a connecting rod.

[0059] In some embodiments of the present application, the first position sensing element 810 and the second position sensing element 820 are position detection sensors or magnetic detection switches for detecting the position of the driving piston.

[0060] When the driving piston of the driving cylinder moves, it can be sensed by the first position sensing element 810 or the second position sensing element 820 when it moves to the position of the first position sensing element 810 or the second position sensing element 820 .

[0061] Specifically, when the driving piston moves to the position of the first position sensing element 810, it means that the material storage container 500 has been filled with materials from the material supply channel 400;

[0062] When the driving piston moves to the position of the second position sensing element 820 , it means that the putty material in the storage container 500 is in a low material state.

[0063] The controller communicates with the first position sensing element 810 and the second position sensing element 820 . The controller can obtain the material status in the accumulator 500 in real time by communicating with the first position sensing element 810 and the second position sensing element 820 .

[0064] The controller is configured to: upon receiving a trigger signal from the second position sensing element 820, control the flow control component 300 to open to a preset opening, and control the driving device 700 to drive the putty pushing member 600 to move away from the putty feeding seat, so as to suck the putty in the hopper 100 into the accumulator 500 through the putty supply channel 400 and the putty outlet channel 210;

[0065] When receiving the trigger signal of the first position sensing element 810, the flow control component 300 is controlled to close, and the driving device 700 is controlled to operate, driving the putty pushing member 600 to move toward the putty feeding seat 200 to send the putty in the storage container 500 out through the putty outlet channel 210.

[0066] Specifically, when the putty automatic continuous extrusion device in this embodiment is in normal working state, the driving piston is located between the first position sensing element 810 and the second position sensing element 820 , and moves from the first position sensing element 810 to the second position sensing element 820 .

[0067] The driving piston applies pressure to the putty pushing member 600 , and the putty pushing member 600 applies pressure to the putty material in the material storage container 500 , so that the pressure on the putty material is pressurized to the working pressure.

[0068] Under the pressure of the driving piston, the putty pushing member 600 pushes the putty in the storage container 500 to move, and the putty is continuously squeezed outward along the putty outlet channel 210 , and the putty is supplied outward from the putty outlet 211 .

[0069] In this embodiment, since a driving cylinder is used to apply air pressure to the putty pushing member 600 and the putty material, the push of the putty pushing member 600 can be stopped when the putty supply is suddenly stopped. At this time, the putty material will not flow out from the putty outlet 211. The putty material in the storage container 500 is pressurized to the working pressure. When material supply is required, the push of the putty pushing member 600 can be continued. Since air pressure is used to push the putty pushing member 600 to move, overload of the driving device 700 can be avoided.

[0070] That is, the air pressure driving method can be used and stopped at any time without overloading or damaging the driving device 700.

[0071] Moreover, the pneumatic pushing method can not only ensure the pushing pressure on the putty in the storage container 500, but also has low cost.

[0072] When the putty automatic continuous extrusion device in this embodiment is in a normal feeding state, the controller controls the flow control component 300 to zero opening to close the putty supply channel 400.

[0073] The driving device 700 drives the putty pushing member 600 to slide along the storage container 500, and continuously applies pressure to the putty in the storage container 500 to push the putty out of the putty outlet channel 210 for putty supply. As the putty supply increases, the putty pushing member 600 continuously pushes the putty in the storage container 500 outward.

[0074] When the driving piston of the driving device 700 moves to the second position sensing element 820, the second position sensing element 820 is triggered, which transmits a signal to the controller. The controller controls the putty pushing member 600 to stay for 0.5S and controls the flow control component 300 to open a certain degree. Then, the driving device 700 is controlled to drive the putty pushing member 600 to make a return movement. Through the effect of negative pressure, the putty material in the material flow enters the putty outlet channel 210 through the putty supply channel 400, and finally enters the storage container 500, so as to realize automatic feeding through negative pressure.

[0075] During feeding, the driving piston continuously moves away from the putty feeding seat 200. When it moves to the first position sensing element 810, it triggers the first position sensing element 810 and transmits a signal to the first position sensing element 810. The controller controls the flow control component 300 to close the putty supply channel 400, and controls the driving device 700 to drive the putty pushing member 600 to continue moving to supply putty.

[0076] The driving device 700 drives the putty pushing member 600 to move back and forth, thereby realizing automatic extrusion and automatic feeding of putty, and realizing continuous and repeated feeding.

[0077] Furthermore, the feeding of putty into the accumulator 500 does not require any human intervention, thereby improving production efficiency.

[0078] In addition, the automatic continuous putty extruder in this embodiment is to convey the putty material forward by sliding the putty pushing member 600 along the side wall of the storage container 500. The pusher is a putty pushing piston, and the contact part between the putty and the putty is flat, so there will be no problem of material jamming.

[0079] During cleaning, the driving device 700 drives the putty pushing member 600 to move, draws in putty from the putty outlet 211 for soaking, and then pumps out the cleaning water from the putty outlet 211, which is convenient for cleaning.

[0080] In some embodiments of the present application, the driving device 700 is a hydraulic cylinder, the piston member 710 is a hydraulic piston rod, and the hydraulic piston rod is fixedly connected to the putty pushing member 600 via a connecting member 900 .

[0081] The putty pushing member 600 can also be driven by the hydraulic piston rod to push the putty to move, and the hydraulic pushing method will not cause the driving device 700 to be damaged due to excessive overload.

[0082] In some embodiments of the present application, it also includes:

[0083] The flow control component 300 is connected between the hopper 100 and the putty coating supply seat, and the putty coating supply channel 400 is formed between the hopper 100, the flow control component 300 and the putty coating supply seat.

[0084] In some embodiments of the present application, a putty coating seat supply channel is provided on the putty coating feed seat 200 , and the putty coating seat supply channel is arranged perpendicular to the putty coating outlet channel 210 .

[0085] Specifically, the putty coating seat feeding channel is arranged vertically, and the putty outlet channel 210 is arranged horizontally.

[0086] The putty feeding channel is arranged vertically, so that the putty material can flow downward in the vertical direction during feeding. The vertical downward flow of the putty and the gravity of the putty can ensure that the putty material can flow quickly and smoothly to the putty outlet channel 210, thereby ensuring the smoothness of the putty supply.

[0087] In some embodiments of the present application, the feed channel of the putty coating seat is a tapered feed channel, and the inner diameter of the tapered feed channel gradually decreases along the flow direction of the putty.

[0088] Setting the feed channel of the putty coating seat to a cone shape can play a guiding role through the cone shape to ensure the smooth flow of the putty material.

[0089] In some embodiments of the present application, the inner diameter of the putty outlet channel 210 gradually decreases along the extrusion direction of the putty. The putty outlet channel 210 is set to have a smaller inner diameter as it is closer to the putty outlet 211, so that the pressure can be concentrated to ensure that the extrusion pressure on the putty at the putty outlet 211 is large enough to ensure that the putty can be smoothly extruded from the putty outlet 211.

[0090] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
