Description

Technical Field

[0001] The invention relates to the technical field of straw processing, in particular to a bamboo straw beveling machine. Background Art

[0002] At present, plastic straws and paper straws are commonly used as straws. Plastic straws are easy to cause environmental pollution after use, and paper straws can only be used once and cannot be reused, resulting in waste of resources. Bamboo straws solve the problems of environmental pollution and waste of resources. They are more environmentally friendly and can be reused like chopsticks, and can replace traditional plastic straws and paper straws. After the bamboo straw is formed into a tubular body, the end still needs to be beveled to form a sharp mouth for easy use.

[0003] For example, the utility model with announcement number CN208946267U discloses a paper straw bevel cutting device, including a cutter and a support seat. The support seat is provided with a lumen for paper straws to be placed in, the lumen has an entrance and an exit, and the support seat is provided with an oblique slot inclined relative to the lumen. The oblique slot passes through the lumen, and the cutter moves back and forth toward the oblique slot to cooperate with the cutting action. A block cooperating with the block is provided at the exit of the lumen, and the block is set to move back and forth at the exit of the lumen. The paper straw bevel cutting device can cut the paper straw in the lumen by beveling through the cooperation between the cutter and the oblique knife groove on the support seat, thereby splitting a paper straw into two, and forming an oblique sharp corner at the separation point of the two paper straws.

[0004] The above technical solution still has the following problems when making an oblique cut on the straw:

[0005] 1. When using, the straw needs to be inserted into the lumen, and then the straw in the lumen needs to be cut obliquely with a cutter. After the cutting is completed, the straw needs to be ejected before the next straw can be processed. There are many steps and the processing efficiency of the straw is affected.

[0006] 2. When the blade makes an oblique cut, there are burrs on the cut edge of the straw, which cannot be removed, which not only affects the subsequent use of the straw, but also affects the appearance of the straw;

[0007] 3. When cutting the oblique cut, wood chips adhere to the outer and inner walls of the straw, causing the user to inhale the wood chips into the mouth when using the straw later.

[0008] In view of the above problems, the present invention document proposes a bamboo straw beveling machine. Summary of the invention

[0009] The invention provides a bamboo straw beveling machine, which solves the shortcomings of the prior art that straws cannot be processed continuously, burrs exist on the edges of the straw cuts, and sawdust adheres to the outer and inner walls of the straws.

[0010] The present invention provides the following technical solutions:

[0012] A cutting structure, arranged on the top of the two support plates, for continuously making oblique cuts on the straws;

[0013] The deburring structure is arranged between the two support plates and is used to remove burrs at the oblique cut of the straw.

[0014] In one possible design, the cutting structure includes a U-shaped frame fixedly connected to the top of two support plates, the top inner wall of the U-shaped frame is fixedly connected to a drive motor, the output shaft of the drive motor is fixedly connected to a blade, the outer wall of the conveyor belt is fixedly connected to a plurality of groove blocks for holding straws, two cross bars are fixedly connected between the two support plates, a plurality of pressure plates are fixedly connected between the two cross bars, and the cross bars and the pressure plates are located below the U-shaped frame, the conveyor belt transports the groove blocks and straws to the right, the pressure plates exert a vertical pressing effect on the straws in the groove blocks, the drive motor is started to drive the blade to rotate at high speed, and the blade makes oblique cuts on the straws transported by the conveyor belt.

[0015] In a possible design, the deburring structure includes a fixed support plate which is closed and fixedly connected to the side of the two support plates close to each other, and the top of the fixed support plate touches the top inner wall of the conveyor belt, so as to support the conveyor belt, and the two fixed support plates are fixedly connected to the side close to each other with a vertical plate, and two second rotating rollers are rotatably connected between the two vertical plates, and the two second rotating rollers are connected by a transmission belt, and a rotating shaft located below the second rotating roller is rotatably connected between the two vertical plates, and the outer wall fixed sleeve of the rotating shaft is provided with a plurality of rubber wheels, and the outer wall of the rubber wheel touches the transmission belt of the outer wall of the second rotating roller, and the outer wall fixed sleeve of the rotating shaft is provided with a first synchronous wheel A second synchronous wheel is provided on the outer wall fixed sleeve of one of the rotating shafts, and the second synchronous wheel is located between the two first rotating rollers. The second synchronous wheel is connected to the first synchronous wheel through a synchronous belt transmission. A cleaning structure for cleaning wood chips on the surface of the transmission belt is provided at the bottom of the two fixed support plates. When one of the rotating shafts rotates, the rubber wheel is driven to rotate through the transmission cooperation of the second synchronous wheel, the synchronous belt and the first synchronous wheel. The rubber wheel contacts the transmission belt on the second rotating roller. The friction between the transmission belt and the rubber wheel drives the second rotating roller and the transmission belt to rotate, so that the transmission belt can grind the outer wall of the rotating straw to remove the burrs on the outer wall of the straw, so as to avoid the burrs on the straw affecting the later use.

[0016] In a possible design, a plurality of fixed plates are fixedly connected to the tops of the two support plates, a plurality of first springs are fixedly connected to the bottoms of the fixed plates, the bottom ends of the plurality of first springs are fixedly connected to the same lifting plate, and the tops of the lifting plates are slidably connected to the fixed plates via round tubes, and a rubber layer is fixedly connected to the bottoms of the lifting plates. When the straw moves below the rubber layer, the thrust of the first springs on the rubber layer can make the bevel cut of the straw tightly contact with the fine sandpaper on the surface of the transmission belt. When the conveyor belt transports the straw to the right through the groove block, the friction between the rubber layer and the straw causes the straw to rotate in the groove block, and the burrs around the bevel cut of the straw can be removed in coordination with the rotation of the transmission belt.

[0017] In one possible design, the cleaning structure includes two L-shaped plates fixedly connected under the two fixed support plates, the two L-shaped plates are fixedly connected by two base plates, a fixed shaft is fixedly connected between the two base plates, the outer wall of the fixed shaft is rotatably sleeved with a connecting rod, the top of the connecting rod is fixedly connected with a fine brush for cleaning wood chips on the surface of the transmission belt, the bottom end of the connecting rod is fixedly connected with an iron load-bearing ball through a connecting rope, and the two L-shaped plates are fixedly connected with a first electromagnet and a second electromagnet on one side close to each other, respectively. When the first electromagnet and the second electromagnet are alternately energized, the first electromagnet and the second electromagnet alternately generate magnetic force and produce magnetic adsorption on the iron load-bearing ball, causing the iron load-bearing ball to drive the connecting rod and the fine brush to swing back and forth, thereby allowing the fine brush to clean the wood chips on the surface of the transmission belt, thereby avoiding excessive wood chips accumulating on the transmission belt and affecting the effect of removing burrs from the transmission belt.

[0018] In a possible design, a vertical plate is rotatably sleeved on the outer wall of one of the rotating shafts, a second contact piece and a first contact piece are fixedly connected to one side of the vertical plate in sequence from top to bottom, two sliding rods are slidably penetrated on one side of the vertical plate, a trapezoidal plate is fixedly connected to the top of the two sliding rods, a third contact piece is fixedly connected to one side of the two trapezoidal plates close to the vertical plate, and the two third contact pieces are respectively matched with the first contact piece and the second contact piece, the trapezoidal plate and the vertical plate are elastically connected by a second spring, and the first rotating roller on the outer wall of one of the rotating shafts A protrusion is fixedly connected to one side of the gear, and the protrusion cooperates with the trapezoidal plate, and the first contact piece and the second contact piece are electrically connected to the first electromagnet and the second electromagnet respectively. When one of the rotating shafts drives one of the first rotating rollers to rotate, the first rotating roller can push the trapezoidal plate to one side and squeeze the second spring through the cooperation of the protrusion and the iron load-bearing ball, so that the third contact piece can be alternately connected with the first contact piece and the second contact piece. At this time, the first electromagnet and the second electromagnet are alternately energized, so that the first electromagnet and the second electromagnet can drive the connecting rod to swing back and forth to remove wood chips on the transmission belt.

[0019] In one possible design, a stopper is fixedly connected to one side of the groove block close to the support plate, and the two groove blocks on the same side cooperate with the corresponding stopper to clamp the straw, thereby preventing the straw from being displaced later when the straw is beveled or deburred, which would cause defects in the beveled or deburred process.

[0020] In a possible design, a plurality of connecting rods are fixedly connected to one side of the two support plates that are close to each other, and a same feed box is fixedly connected to one end of the plurality of connecting rods that are close to each other, and the feed box is located above the groove block, and the conveyor belt drives the groove block to operate. When the groove block is located directly below the feed box, the straws in the feed box automatically fall into the groove block under the action of gravity. This is simple and convenient, and the task of placing the straws can be completed without the need for an additional driving structure.

[0021] In a possible design, a collecting box located below the conveyor belt is fixedly connected between the two support plates, a baffle located above the groove block is fixedly connected between the two support plates, and the baffle is located in the U-shaped frame. When the blade makes an oblique cut on the straw, the baffle can prevent wood chips from splashing everywhere, and the collecting box can collect the wood chips.

When the straws fall on the screen plate, the wood chips attached to the straws are initially shaken off, and the fan is started. The wind force generated by the fan can continue to blow the wood chips attached to the inner and outer walls of the straws into the water in the box body, thereby avoiding the wood chips from being lifted up.

[0023] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0024] In the present invention, two cross bars are fixedly connected between the two support plates, and a plurality of pressing plates are fixedly connected between the two cross bars, and the cross bars and the pressing plates are located below the U-shaped frame.

[0025] In the present invention, two second rotating rollers are rotatably connected between the two vertical plates, and the two second rotating rollers are connected by a transmission belt. The two vertical plates are rotatably connected to a rotating shaft, and a plurality of rubber wheels are provided on the outer wall fixed sleeve of the rotating shaft. The rotating shaft and one of the rotating shafts are connected by a synchronous belt transmission. When the rotating shaft rotates, the rotating shaft and the rubber wheel are driven to rotate, and the rubber wheel contacts the transmission belt on the second rotating roller. The friction between the transmission belt and the rubber wheel drives the second rotating roller and the transmission belt to rotate, and then the transmission belt can grind the outer wall of the rotating straw to remove the burrs on the outer wall of the straw, so as to avoid the burrs on the straw affecting the later use.

When the straws fall on the sieve plate 48, the wood chips attached to the straws are initially shaken off, and the fan 47 is started. The wind force generated by the fan 47 can continue to blow the wood chips attached to the inner and outer walls of the straws into the water in the box body 45, thereby avoiding the wood chips from being lifted up.

[0070] The working principle of a bamboo straw beveling machine is as follows: straws are uniformly put into a feed box 7, a servo motor (not shown in the figure) is started to drive the rotating shaft 2, the first rotating roller 3, and the conveyor belt 4 to run, and the conveyor belt 4 drives the groove block 5 to run.

[0071] The conveyor belt 4 conveys the cut straws to the right. When the straws move to the bottom of the rubber layer 16, the thrust of the first spring 14 on the rubber layer 16 can make the straws tightly touch the fine sandpaper on the surface of the conveyor belt 20. When the conveyor belt 4 conveys the straws to the right through the groove block 5, the friction between the rubber layer 16 and the straws causes the straws to rotate in the groove block 5.

At this time, the first electromagnet 27 and the second electromagnet 35 are alternately energized, and the first electromagnet 27 and the second electromagnet 35 alternately generate magnetic force and generate magnetic attraction to the iron bearing ball 33, causing the iron bearing ball 33 to drive the connecting rod 30 and the fine brush 31 to swing back and forth.
