[0002] In production, bamboo powder can usually be used as the raw material for bamboo bowls and chopsticks. It not only gives the product a unique appearance and texture, but also improves its physical properties and environmental characteristics. In order to ensure a good combination between bamboo powder and plastic substrate, an appropriate amount of adhesive is usually added, and the mixing device can ensure that the bamboo powder and the adhesive are fully combined, thereby ensuring uniform distribution of the material, improving the strength and stability of the finished product, and avoiding product defects caused by uneven mixing, such as stratification, bubbles or inconsistent strength, so as to make beautiful and durable bamboo bowls.

[0003] During the batch mixing process, raw materials tend to adhere to the equipment, resulting in adhesion and agglomeration during subsequent stirring, affecting mixing uniformity and product quality.

The mixing rack penetrates the rotating plate and is slidably connected to the rotating plate. The stirring blades of the mixing rack are arranged in an arc shape. When the rotating plate moves downward, the mixing rack will be squeezed to rotate along the barrel cover. The barrel cover is fixedly connected to an electric telescopic rod symmetrically distributed along the barrel cover, and the telescopic end of the electric telescopic rod is fixedly connected to a connecting block, which is slidably connected to the rotating plate. The barrel cover is slidably connected to a force-bearing rod symmetrically distributed along the barrel cover, and the rotating plate contacts one end of the force-bearing rod. A bottom cover is slidably connected in the mixing barrel, and the bottom cover is fixedly connected to the other end of the force-bearing rod, and a discharge chute is provided on the bottom cover.

[0008] In a preferred embodiment of the present invention, a scraper frame is also included. The scraper frame is slidably connected to the middle of the bottom cover. An embedding groove is opened in the middle of the bottom cover. The top of the scraper frame is located in the embedding groove. A guide frame is fixedly connected to the middle of the telescopic base. The guide frame is slidably connected to the scraper frame.

[0009] In a preferred embodiment of the present invention, a reset plate is further included. The reset plate is slidably connected to the scraper frame, the reset plate is located in the embedding groove of the bottom cover, and a plurality of first springs are fixedly connected between the reset plate and the bottom cover.

[0010] In a preferred embodiment of the present invention, a fixing ring is further included, which is fixed to the side of the rotating rod close to the gear set. The side of the rotating rod close to the fixing ring is slidably connected to a blocking frame. The rotating plate moves upward to contact the blocking frame, and the blocking frame moves downward to block the fixing ring.

[0011] In a preferred embodiment of the present invention, it also includes a connecting frame, which is fixedly connected to the rotating rod. The connecting frame is slidably connected to a circumferentially distributed bracket, a second spring is fixedly connected between the bracket and the connecting frame, the connecting frame is clamped with a connecting rod through the bracket, an extrusion portion is provided at the lower part of the connecting rod, and the connecting rod is extruded and matched with the bracket through the extrusion portion.

[0015] When the rotating plate of the present invention descends to contact the top of the scraper, the rotating plate rotates to allow the scraper to scrape off the material at the bottom, thereby achieving the effect of automatically cleaning the rotating plate.

[0016] When the top of the scraper frame extends out from the embedding groove of the bottom cover, the first spring is reset to drive the reset plate to quickly slide upwards and timely block the embedding groove to prevent the mixed material from entering the embedding groove.

[0017] The present invention disengages from the baffle when the rotating plate moves downward, and utilizes the baffle to slide downward under its own gravity to block the fixing ring, thereby automatically stopping the feeding of the water-based adhesive, preventing the water-based adhesive from being input during the discharge of the mixed material, causing the cleaned area to be contaminated again.

[0018] The present invention provides an additional connecting rod rotatable relative to the rotating rod on the rotating rod, so that the output pipe of the external water-based adhesive grouting machine is no longer connected to the rotating rod but to the connecting rod, thereby preventing the output pipe from rotating and getting tangled during the mixing process.

DETAILED DESCRIPTION

[0030] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0031] Embodiment 1: A self-cleaning bamboo powder mixing device for preventing raw materials from adhering, such as Figure 1-Figure 3 As shown, it includes a telescopic base 1, the telescopic base 1 is provided with four support rods along the circumferential direction, the two support rods on the rear side of the telescopic base 1 are set as telescopic rods, the top ends of the four support rods of the telescopic base 1 are rotatably connected with mounting blocks 2, a mixing barrel 3 is fixedly connected between the four mounting blocks 2, a material pipe for feeding bamboo powder is provided on the upper front side of the mixing barrel 3, a barrel cover 4 is fixedly connected to the top of the mixing barrel 3, a rotating rod 6 is rotatably connected to the middle axial through-through of the barrel cover 4, the rotating rod 6 is set as a round tube for conveying water-based adhesive, the lower part of the rotating rod 6 is provided with evenly distributed liquid outlet holes along the axial direction, the rotating rod 6 is spline-connected with a rotating plate 5, the rotating plate 5 is located in the mixing barrel 3 and contacts with the inner wall of the mixing barrel 3, a motor 7 is fixedly connected to the left part of the barrel cover 4, and the output shaft of the motor 7 is connected to the rotating rod 6 The transmission is transmitted through the gear set 8. The inner wall of the cylinder cover 4 is rotatably connected with the inner and outer mixing frames 9. The mixing frame 9 penetrates the rotating plate 5 and is slidably connected to the rotating plate 5. The stirring blades of the mixing frame 9 are set to an arc shape. When the rotating plate 5 moves downward, it will squeeze the mixing frame 9 to rotate along the cylinder cover 4. The cylinder cover 4 is fixed with an electric telescopic rod 10 symmetrically distributed along the cylinder cover 4. The telescopic end of the electric telescopic rod 10 is fixed with a connecting block 11, and the connecting block 11 is slidably connected to the rotating plate 5. The cylinder cover 4 is slidably connected with a force-bearing rod 12 symmetrically distributed along the cylinder cover 4 in the up and down direction. The top of the rotating plate 5 contacts the upper end of the force-bearing rod 12. The lower part of the mixing cylinder 3 is slidably connected with a bottom cover 13 in the up and down direction. The bottom cover 13 is fixed to the lower end of the force-bearing rod 12, and a discharge chute is provided on the front side of the bottom cover 13.

[0032] First, the output pipe of the water-based adhesive grouting machine is connected to the top of the rotating rod 6, and the discharge pipe of the bamboo powder is connected to the material pipe of the mixing barrel 3. Then, the motor 7 is started, and the output shaft of the motor 7 drives the gear set 8 to rotate, thereby driving the rotating rod 6 to rotate, and then driving the rotating plate 5 to rotate relative to the connecting block 11, and then driving the inner and outer mixing frames 9 to rotate. Then, the water-based adhesive is injected into the rotating rod 6, and then flows evenly into the mixing barrel 3 through the liquid outlet holes evenly distributed on the axial direction of the rotating rod 6. At the same time, the bamboo powder is discharged into the mixing barrel 3. In this way, the bamboo powder and the water-based adhesive are evenly mixed.

[0033] After mixing to a certain extent, the electric telescopic rod 10 is controlled to extend downward, thereby driving the connecting block 11 to move downward, and then driving the rotating plate 5 to move downward. When the rotating plate 5 is disengaged downward from the upper part of the force-bearing rod 12, the force-bearing rod 12 slides downward under the action of gravity, thereby driving the bottom cover 13 to slide downward, so that the discharge trough of the bottom cover 13 is exposed outside the mixing barrel 3, and the rotating plate 5 squeezes the mixed material in the mixing barrel 3 downward out of the discharge trough of the bottom cover 13, thus achieving the effect of discharging. After the discharging is completed, the motor 7 is turned off, and the electric telescopic rod 10 is controlled to shorten upward, thereby driving the connecting block 11 to move upward, and then driving the rotating plate 5 to move upward. When the rotating plate 5 contacts the upper part of the force-bearing rod 12 upward, the rotating plate 5 pushes the force-bearing rod 12 to slide upward, thereby driving the bottom cover 13 to slide upward, so that the discharge trough of the bottom cover 13 enters the mixing barrel 3.

[0034] During the above-mentioned discharging process, the rotating plate 5 moves downward to scrape off the mixed material adhered to the inner wall of the mixing drum 3. At the same time, it also scrapes off the mixed material adhered to the inner and outer mixing racks 9. In this way, the effect of automatically cleaning the inner wall of the mixing drum 3 and the mixing rack 9 while discharging is achieved.

[0035] like Figure 1-Figure 4 As shown, it also includes guide rods 14 that are symmetrically distributed along the cylinder cover 4. The guide rods 14 are slidably connected between the cylinder cover 4 and the mixing cylinder 3 along the up and down directions. A guide frame 15 is fixedly connected to the rear side of the telescopic base 1. The front side of the guide frame 15 is provided with an inclined surface. The lower side of the guide rod 14 is pressed and matched with the inclined surface of the guide frame 15, and the upper side of the guide rod 14 is pressed and matched with the adjacent electric telescopic rod 10.

[0036] When the electric telescopic rod 10 is extended downward step by step, the electric telescopic rod 10 squeezes the upper end of the guide rod 14, so that the guide rod 14 slides backward along the barrel cover 4. During the backward sliding process, the guide rod 14 is also acted on by the inclined surface of the guide frame 15 and is pushed upward, so that the mixing barrel 3 and the barrel cover 4 are higher at the back and lower at the front, and then the mixing barrel 3, the barrel cover 4 and the components thereon are tilted slightly forward as a whole, so that the mixed material in the mixing barrel 3 is discharged forward and downward through the discharge chute of the bottom cover 13 in a pouring manner.

[0037] When the electric telescopic rod 10 is gradually shortened and reset upward, the electric telescopic rod 10 is separated from the upper end of the guide rod 14. At this time, the mixing cylinder 3 drives the cylinder cover 4 to be reset to the right position under the action of its own center of gravity balance. Under the extrusion of the inclined surface of the guide frame 15, the guide rod 14 slides forward along the cylinder cover 4 to reset.

[0038] like Figure 5 and Figure 6 As shown, a scraper frame 16 is also included. The scraper frame 16 is set in a T shape. The scraper frame 16 is slidably connected to the middle of the bottom cover 13. An embedding groove is opened in the middle of the bottom cover 13. The top of the scraper frame 16 is located in the embedding groove. A guide frame 17 is fixedly connected to the middle of the telescopic base 1. The guide frame 17 is slidably connected to the scraper frame 16. The upper part of the scraper frame 16 is slidably connected to a reset plate 18 in the up and down directions. The reset plate 18 is located in the embedding groove of the bottom cover 13. Four first springs 19 are fixedly connected between the reset plate 18 and the bottom cover 13.

[0039] Initially, the bottom end of the scraper 16 contacts the telescopic base 1, the top of the scraper 16 is embedded in the bottom cover 13 and is flush with the inner bottom surface of the bottom cover 13, the first spring 19 is in a compressed state, and when the mixing drum 3 tilts slightly forward, the mixing drum 3 drives the scraper 16 to tilt slightly forward synchronously through the bottom cover 13, and the guide frame 17 supports and guides the scraper 16. When the bottom cover 13 slides downward along the mixing drum 3, the bottom cover 13 slides downward relative to the scraper 16 at the same time. When the rotating plate 5 descends to contact the top of the scraper 16, the rotating plate 5 rotates to allow the scraper 16 to scrape off the bottom material, thereby automatically cleaning the rotating plate 5.

[0040] Since the top of the scraper 16 is initially embedded in the bottom cover 13, an embedding groove for the scraper 16 is opened in the middle of the bottom cover 13. When the bottom cover 13 slides downward relative to the scraper 16, the top of the scraper 16 extends out of the embedding groove of the bottom cover 13, causing the mixed material to enter the embedding groove and become difficult to clean. Therefore, when the top of the scraper 16 extends out of the embedding groove of the bottom cover 13, the reset plate 18 is driven by the first spring 19 to slide upward quickly to block the embedding groove in time, thereby preventing the mixed material from entering the embedding groove.

[0041] like Figure 7 and Figure 8 As shown, it also includes a fixing ring 20, which is fixed to the upper side of the rotating rod 6. The upper part of the rotating rod 6 is slidably connected to a blocking frame 21 along the up and down directions. The rotating plate 5 moves upward to contact the blocking frame 21, and the blocking frame 21 moves downward to block the fixing ring 20.

[0042] When the rotating plate 5 moves downward, the rotating plate 5 is separated from the blocking frame 21, and the blocking frame 21 slides downward under the action of its own gravity to block the fixing ring 20, thereby automatically stopping the feeding of the water-based adhesive to prevent the grouting machine from being accidentally touched during cleaning, resulting in the water-based adhesive still being input during the discharge of the mixed material, thereby causing the cleaned area to be contaminated again.

[0043] When the rotating plate 5 moves upward to contact the blocking frame 21 , the rotating plate 5 pushes the blocking frame 21 to move upward, so that the blocking frame 21 no longer blocks the fixing ring 20 , thereby allowing the water-based adhesive to be input.

[0044] like Figure 1 , Fig. 9 and Fig.10 As shown, it also includes a connecting frame 22, which is fixedly connected to the rotating rod 6. The connecting frame 22 is slidably connected to four circumferentially distributed brackets 23, and a second spring 24 is fixedly connected between the bracket 23 and the connecting frame 22. The connecting frame 22 is clamped with a connecting rod 25 through the bracket 23. An extrusion portion is provided at the lower part of the connecting rod 25, and the connecting rod 25 is extruded and matched with the bracket 23 through the extrusion portion. The connecting rod 25 is slidably connected to an unlocking piece 26 in the up and down directions, and the unlocking piece 26 is extruded and matched with the bracket 23.

[0045] Since the rotating rod 6 needs to rotate during the mixing process, the output pipe of the external water-based adhesive grouting machine also needs to rotate, which may cause the output pipe to be easily tangled. To avoid this situation, the following operations are performed: The connecting rod 25 is pressed downwardly against the bracket 23, so that the bracket 23 slides toward the side of the compressed second spring 24, thereby causing the extruded portion of the connecting rod 25 to squeeze downward into the connecting frame 22. At this time, the second spring 24 is reset to drive the bracket 23 to slide in the opposite direction to reset, thereby clamping the extruded portion of the connecting rod 25, so that the extruded portion of the connecting rod 25 cannot be easily pulled out of the connecting frame 22 upward. In this way, by additionally providing a connecting rod 25 that can rotate relative to the rotating rod 6 on the rotating rod 6, the output pipe of the external water-based adhesive grouting machine is no longer connected to the rotating rod 6, but connected to the connecting rod 25, which can prevent the output pipe from rotating and getting knotted during the mixing process.

[0046] When the output tube needs to be pulled out, the unlocking member 26 is first pressed downwards. The unlocking member 26 squeezes the bracket 23 and slides toward the side where the second spring 24 is compressed again, so that the connecting rod 25 can be pulled out, thereby pulling out the output tube. Finally, the unlocking member 26 is released, and the second spring 24 is reset to drive the bracket 23 to slide in the opposite direction and reset.

[0047] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
