[0001] The invention relates to the technical field of raw material feeding for roto-molding boxes, in particular to a raw material feeding device for roto-molding box production. Background Art

[0002] The main raw material for producing roto-molded boxes is polyethylene. These materials not only have good physical properties, but also have the advantages of environmental protection and durability. At the same time, roto-molded boxes have a wide market in life and bring great convenience to people's storage of items.

[0003] Patent announcement number CN218987989U discloses a raw material feeding device for a plastic lunch box, including a base, a groove is provided inside the base, a motor 1 is fixedly connected inside the groove, a threaded rod is fixedly connected to the output end of the motor 1, a moving block is threadedly connected to the outside of the threaded rod, a fixed frame is fixedly connected to the left side of the upper part of the base, a rotating rod is rotatably connected to the opposite side of the fixed frame, a connecting block is rotatably connected to the outside of the rotating rod, a collecting box is rotatably connected to the upper part of the connecting block, a fixed box is fixedly connected to the right part of the base, and a placement box is fixedly connected to the upper part of the fixed box. This patent realizes the automatic transportation of raw materials, reduces the labor intensity of manual labor, and improves the practicality of the device.

[0004] However, the device still has some shortcomings: the device can reduce the intensity of manual labor, but in the process of conveying the raw material of the rotational molding box, namely polyethylene, since polyethylene is fine particles and relatively loose, it is easy to fall off after being disturbed by the vibration during the operation of the equipment during large-scale loading. In the long run, it is easy to increase the loss of raw materials and thus increase economic expenditure. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a raw material feeding device for roto-molding box production, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a raw material feeding device for roto-molding box production, comprising a support table, a material receiving assembly is arranged on the right side of the support table, a fixed plate is arranged on the left side of the top of the support table, a U-shaped frame is arranged on the left side of the outer wall of the fixed plate, and a feed port is arranged at the top of the U-shaped frame, a transmission assembly is arranged on the top of the support table, and a conveyor belt is arranged on the outer wall of the transmission assembly; The outer wall of the transmission assembly is provided with an anti-drop device, the inner side of the anti-drop device is provided with an anti-corrosion device, and the outer side of the anti-corrosion device is provided with an anti-adhesion device; The anti-drop device includes an electric rotating rod, both ends of which are rotatably installed inside a fixed plate, both ends of the electric rotating rod are provided with reciprocating spiral grooves, a plurality of trough plates are equidistantly and fixedly installed on the outer wall of the middle end of the electric rotating rod, a transmission plate is penetrated through and movably installed on the outer wall of the reciprocating spiral groove of the electric rotating rod, a U-shaped push plate is slidably installed on the top of the support platform, the inner wall of the U-shaped push plate close to one end of the conveyor belt is fixedly connected to the outer wall of the transmission plate, an L-shaped baffle is fixedly installed on the side of the U-shaped push plate close to the conveyor belt, and the bottom of the L-shaped baffle is in contact with the top edge of the conveyor belt, a plurality of pulleys are symmetrically and rotatably installed inside the U-shaped groove of the L-shaped baffle, a screw rod is fixedly installed on the side of the pulley close to the center of the L-shaped baffle, a plurality of arc panels are penetrated through and threadedly connected on the outer wall of the screw rod, and a hollow tough plate is fixedly installed on the top of the inner wall of the L-shaped baffle.

[0007] The U-shaped groove is formed inside the L-shaped baffle plate, and the outer walls of several pulleys are in contact with the top of the conveyor belt. The outer walls of several arc panels are slidably connected to the inner walls of the U-shaped grooves of the L-shaped baffle plate. The bottom of the hollow tough plate is located on the movement trajectory of the top of the arc panel, and the external pipeline is connected to the inside of the feed port of the U-shaped frame. Polyethylene is transported to the inside of the fixed plate through the external pipeline. Prior to this, the electric rotating rod is started. When the electric rotating rod rotates along the inner wall of the fixed plate, it drives the trough plate to revolve. The trough plate receives the polyethylene through its own internal space. At the same time, when the trough plate flips, it causes the polyethylene to fall into the top of the conveyor belt in batches. The conveyor belt drives the polyethylene from left to right through the transmission of the transmission component until the raw material falls into the inside of the receiving component. When the electric rotating rod rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the transmission plate, so that the transmission plate can reciprocate horizontally along its own outer wall and reset. The L-shaped plate is pressed against the bottom surface of the L-shaped plate, and the L-shaped plate is pressed against the bottom surface of the L-shaped plate, and the L-shaped plate is pressed against the bottom surface of the L-shaped plate.

[0008] According to the above technical solution, the anti-corrosion device includes several sliding plates, hinged plates and hollow cylinders. The bottoms of the sliding plates are symmetrical and slidably installed at the top edge of the support platform. The bottom of the hinged plate is hinged to the top of the sliding plate, and a square groove is opened inside the hinged plate. The outer wall of the hollow cylinder is hinged to the top of the hinged plate.

[0009] When the U-shaped push plate is reset, the sliding plate is reset by the spring force and reciprocates. The sliding plate reciprocates and moves toward the center of the support platform and resets, driving the hinged plate to move synchronously. When the hinged plates on both sides move synchronously toward the center of the support platform, they are limited by the hollow cylinder. At this time, the hinge shaft of the hinged plate starts to rotate and pushes the hollow cylinder to move upward and deforms against the bottom of the conveyor belt.

[0010] According to the above technical scheme, the anti-erosion device also includes a dryer, a cross bar, an air guide plate and a contact plate. The outer wall of the air dryer is fixedly installed inside the square groove of the hinged plate, and the end of the cross bar away from the air dryer is fixedly installed on the inner wall of the square groove of the hinged plate. The air guide plate is penetrated by a torsion spring and is hinged to the outer wall of the cross bar. The contact plate is fixedly installed on the side of the air guide plate close to the hollow cylinder. When the hinged plate moves in an arc-shaped trajectory toward the center of the support platform, it drives the air dryer to move synchronously. At the same time, the hinged plate also drives the cross bar and the air guide plate to move synchronously. In the process of the air guide plate driving the contact plate to move synchronously, the contact plates of each air guide plate will contact the outer wall of the opposite air guide plate to generate a resistance force. At this time, the hinge axis of the air guide plate starts to rotate and flips along the outer wall of the cross bar.

[0011] According to the above technical scheme, the anti-adhesion device includes a plurality of sliding blocks, round rods and wave plates. The sliding blocks are slidably installed on the outer wall of the hinged plate by springs on the side close to the air guide plate. Both ends of the round rods are fixedly installed on the side of the sliding block close to the center of the conveyor belt. The round rod is located on the movement trajectory of the air guide plate. The wave plate is fixedly installed on the outer wall of the sliding block away from the air guide plate. When the air guide plate flips, it contacts the outer wall of the round rod to generate a resistance force. At this time, the round rod generates a downward force under the push of the air guide plate. The round rod drives the sliding block to slide downward along the outer wall of the hinged plate. After that, the sliding block drives the round rod to reset when the torsion spring is reset and repeats this process. The sliding block reciprocates downward and resets, driving the wave plate to move synchronously.

[0012] According to the above technical solution, the anti-adhesion device also includes an L-shaped plate, a limit frame, a rotating rod, a friction wheel and a plurality of retractable brush plates. The bottom of the L-shaped plate is hinged inside the sliding block, the limit frame is fixedly installed on the outer wall of the L-shaped plate away from the side of the wave plate, both ends of the rotating rod are rotatably installed inside the limit frame, the friction wheel passes through the inside and is fixedly installed on the outer wall of the rotating rod, and the plurality of retractable brush plates are equidistant and fixedly installed on the outer wall of the rotating rod.

[0013] According to the above technical scheme, a torsion spring is arranged between the bottom of the L-shaped plate and the sliding block, the outer wall of the friction wheel contacts the bottom of the conveyor belt, and the outer wall of the telescopic end of the telescopic brush plate contacts the bottom of the conveyor belt. The sliding block slides back and forth downward and resets, driving the L-shaped plate to move synchronously, the L-shaped plate drives the limit frame to move synchronously, the limit frame drives the rotating rod to move synchronously, the rotating rod drives the friction wheel to move synchronously and rub along the bottom of the conveyor belt, the friction wheel drives the rotating rod to rotate when it rotates through friction force, and the rotating rod drives the telescopic brush plate to rotate when it rotates, and the top of the telescopic end of the telescopic brush plate brushes the bottom of the conveyor belt while the telescopic brush plate gradually moves away from the center of the conveyor belt.

[0014] The present invention provides a raw material feeding device for roto-molding box production. It has the following beneficial effects: (1) The present invention sets an anti-drop device, and cooperates with an electric rotating rod, a trough plate, a transmission plate, a U-shaped push plate, an L-shaped baffle plate, a pulley, a screw rod, a curved plate and a hollow flexible plate. The trough plate enables the raw materials to be loaded in batches and continuously, thereby ensuring the loading efficiency and avoiding the accumulation of raw materials. At the same time, the L-shaped baffle plate effectively ensures that the loose raw materials are always loaded close to the center of the conveyor belt, thereby avoiding the drop of raw materials caused by the vibration during the operation of the equipment during large-scale loading, thereby avoiding the increase of raw material loss; and effectively reduces the wear of the conveyor belt, thereby extending the service life. At the same time, the vibration force is used to reduce the friction between the raw materials and the conveyor belt when the L-shaped baffle plate pushes the raw materials, thereby preventing the L-shaped baffle plate from crushing the raw materials, thereby ensuring the individual integrity of polyethylene during the loading process and reducing the loss of raw materials during the loading process.

[0015] (2) The present invention sets an anti-corrosion device, and cooperates with a U-shaped push plate, a sliding plate, a hinged plate, a hollow cylinder, an air dryer, a cross bar, an air guide plate and a resistance plate. The resistance force of the hollow cylinder causes the top of the conveyor belt to slightly concave and deform, thereby slightly changing the flat conveying posture of the top of the conveyor belt, preventing the top of the conveyor belt from collapsing and deforming during a long period of loading, while reducing the viscosity between the damp raw materials and the conveyor belt, thereby facilitating the raw materials to separate from the top of the conveyor belt; at the same time, by effectively changing the blowing amplitude of the air dryer to expand the blowing range, the air drying rate of the conveyor belt is improved, and the flipped air guide plate releases the relatively sealed environment at the bottom of the conveyor belt, no longer blocks external dirt, and increases the circulation speed between the bottom of the conveyor belt and the external air during the loading process, further improving the air drying rate of the conveyor belt, preventing moisture from corroding the raw materials and reducing the performance.

[0016] (3) The present invention, through the setting of the anti-adhesion device, cooperates with the air guide plate, sliding block, round rod, wave plate, L-shaped plate, limit frame, rotating rod, friction wheel and telescopic brush plate, and relies on the reciprocating motion of the wave plate to disturb the airflow around the air guide plate, thereby effectively extending the time for external air to enter the bottom range of the conveyor belt, that is, extending the drying time of the external airflow by the air dryer, avoiding the external airflow carrying moisture and thus aggravating the erosion of the conveyor belt, and preventing the raw materials from being further damp during the loading process, which may cause defects such as pores to appear on the surface of the finished product; and promoting the telescopic end of the telescopic brush plate to always brush closely against the bottom of the conveyor belt through the push of the built-in spring, thereby avoiding the telescopic end of the telescopic brush plate from being separated from the bottom of the conveyor belt due to the change in the angle of the L-shaped plate in some time periods, preventing the telescopic brush plate from brushing the conveyor belt for a period of time, preventing the telescopic brush plate from brushing the conveyor belt for a period of time, preventing the outer wall of the conveyor belt from having raw material residues attached during the transmission and loading cycle, and preventing the raw material residues from being processed and produced simultaneously, thereby reducing the durability of the finished product.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 9 One embodiment of the present invention is: a raw material feeding device for roto-molding box production, comprising a support platform 1, a material receiving assembly 2 is arranged on the right side of the support platform 1, a fixing plate 3 is arranged on the left side of the top of the support platform 1, a U-shaped frame 31 is arranged on the left side of the outer wall of the fixing plate 3, and a feeding port is arranged at the top of the U-shaped frame 31, a transmission assembly 32 is arranged on the top of the support platform 1, and a conveyor belt 33 is arranged on the outer wall of the transmission assembly 32; The outer wall of the transmission assembly 32 is provided with an anti-drop device 4, the inner side of the anti-drop device 4 is provided with an anti-corrosion device 5, and the outer side of the anti-corrosion device 5 is provided with an anti-adhesion device 6; The anti-drop device 4 includes an electric rotating rod 41, both ends of which are rotatably installed inside the fixed plate 3, both ends of the electric rotating rod 41 are provided with reciprocating spiral grooves, a plurality of trough plates 42 are equidistantly and fixedly installed on the outer wall of the middle end of the electric rotating rod 41, a transmission plate 43 is penetrated through the outer wall of the reciprocating spiral groove of the electric rotating rod 41 and movably installed, a U-shaped push plate 44 is slidably installed on the top of the support platform 1, the inner wall of the U-shaped push plate 44 close to one end of the conveyor belt 33 is fixedly connected to the outer wall of the transmission plate 43, an L-shaped baffle 45 is fixedly installed on the side of the U-shaped push plate 44 close to the conveyor belt 33, and the bottom of the L-shaped baffle 45 is in contact with the top edge of the conveyor belt 33, a plurality of pulleys 46 are symmetrically and rotatably installed inside the U-shaped groove of the L-shaped baffle 45, a screw rod 47 is fixedly installed on the pulley 46 close to the center side of the L-shaped baffle 45, a plurality of arc panels 48 are penetrated through the outer wall of the screw rod 47 and are threadedly connected, and a hollow tough plate 49 is fixedly installed on the top of the inner wall of the L-shaped baffle 45.

[0021] A U-shaped groove is provided inside the L-shaped baffle plate 45, and the outer walls of several pulleys 46 are in contact with the top of the conveyor belt 33, and the outer walls of several arc panels 48 are slidably connected to the inner wall of the U-shaped groove of the L-shaped baffle plate 45, and the bottom of the hollow tough plate 49 is located on the movement trajectory of the top of the arc panel 48. Through the above cooperation, the trough plate 42 is used to enable the raw materials to be fed in batches and continuously, thereby ensuring the feeding efficiency while avoiding the accumulation of raw materials. At the same time, the L-shaped baffle plate 45 effectively ensures that the loose raw materials are always fed close to the center of the conveyor belt 33, thereby avoiding the falling of raw materials due to the interference of vibration during the operation of the equipment during large-scale feeding, thereby avoiding increased raw material loss; through the above cooperation, the wear of the conveyor belt 33 is effectively reduced, thereby extending the service life, and at the same time, the vibration force is used to reduce the friction between the raw materials and the conveyor belt 33 when the L-shaped baffle plate 45 pushes the raw materials, thereby preventing the L-shaped baffle plate 45 from crushing and crushing the raw materials, thereby ensuring the individual integrity of polyethylene during the feeding process, and reducing the loss of raw materials during the feeding process.

[0022] When in use, the external pipeline is connected to the inside of the feed port of the U-shaped frame 31, and the polyethylene is transported to the inside of the fixed plate 3 through the external pipeline. Before this, the electric rotating rod 41 is started. When the electric rotating rod 41 rotates along the inner wall of the fixed plate 3, it drives the trough plate 42 to revolve. The trough plate 42 receives the polyethylene through its own internal space. At the same time, when the trough plate 42 turns over, the polyethylene is caused to fall into the top of the conveyor belt 33 in batches. The conveyor belt 33 drives the polyethylene from left to right through the transmission component 32 until the raw material falls into the inside of the receiving component 2. When the electric rotating rod 41 rotates, the reciprocating spiral groove on its outer wall drives the built-in card of the transmission plate 43 The restriction of the block causes the transmission plate 43 to be able to reciprocate horizontally along its own outer wall and reset. The transmission plate 43 pushes the U-shaped push plate 44 to move along the top of the support platform 1 toward the direction close to the conveyor belt 33 and reset. The U-shaped push plate 44 drives the L-shaped baffle 45 to move synchronously along the top of the conveyor belt 33. During the movement of the L-shaped baffle 45, the raw materials at the edge will be pushed toward the center of the conveyor belt 33. Through the above cooperation, the trough plate 42 is relied on to enable the raw materials to be loaded in batches and uninterruptedly, ensuring the loading efficiency while avoiding the accumulation of raw materials. At the same time, the L-shaped baffle 45 effectively ensures that the loose raw materials are always loaded close to the center of the conveyor belt 33 , to prevent the raw materials from falling due to the interference of the vibration during the operation of the equipment during the large-scale loading process, and to prevent the increase of raw material loss; the U-shaped groove of the L-shaped baffle 45 drives the pulley 46 to move along the top of the conveyor belt 33 toward the center thereof, and friction is generated. The pulley 46 rotates inside the L-shaped baffle 45 through the friction force. The pulley 46 reduces the wear between the L-shaped baffle 45 and the conveyor belt 33. At the same time, the pulley 46 drives the screw rod 47 to rotate when rotating. When the screw rod 47 rotates, the spiral groove drives the threaded arc panel 48 to slide horizontally along the inner wall of the U-shaped groove of the L-shaped baffle 45. During the sliding process, the arc panel 48 contacts the bottom end of the hollow tough plate 49 Contact and resistance force are generated, and the bottom end of the hollow flexible plate 49 is bent and deformed due to the resistance force. At the same time, the arc surface guide between the two facilitates the arc panel 48 to pass over the hollow flexible plate 49. When the hollow flexible plate 49 is reset by its own toughness, it will swing back and forth, thereby causing the L-shaped baffle 45 to vibrate slightly. The above cooperation can effectively reduce the wear of the conveyor belt 33 and extend its service life. At the same time, the vibration force is used to cause the L-shaped baffle 45 to push the raw material, reduce the friction between the raw material and the conveyor belt 33, and prevent the L-shaped baffle 45 from crushing and crushing the raw material, thereby ensuring the individual integrity of polyethylene during the feeding process and reducing the loss of raw materials during the feeding process.

[0023] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-corrosion device 5; The anti-corrosion device 5 includes a plurality of sliding plates 51, hinged plates 52 and a hollow cylinder 53. The bottoms of the plurality of sliding plates 51 are symmetrical and slidably installed at the top edge of the support platform 1. The bottom of the hinged plate 52 is hinged to the top of the sliding plate 51, and a square groove is provided inside the hinged plate 52. The outer wall of the hollow cylinder 53 is hinged to the top of the hinged plate 52.

[0024] The outer wall of the sliding plate 51 is in contact with the side of the U-shaped push plate 44 close to the conveyor belt 33, a spring is arranged between the bottom of the sliding plate 51 and the support platform 1, a torsion spring is arranged between the hinged plate 52 and the sliding plate 51, and the top of the hollow cylinder 53 is in contact with the center of the bottom of the conveyor belt 33. Through the above cooperation, the resistance force of the hollow cylinder 53 causes the top of the conveyor belt 33 to be slightly concave and deformed, thereby slightly changing the flat conveying posture of the top of the conveyor belt 33, preventing the top of the conveyor belt 33 from collapsing and deforming during a long period of loading, while reducing the viscosity between the damp raw materials and the conveyor belt 33, thereby facilitating the raw materials to detach from the top of the conveyor belt 33.

[0025] The anti-corrosion device 5 also includes a dryer 54, a cross bar 55, an air guide plate 56 and a contact plate 57. The outer wall of the dryer 54 is fixedly installed inside the square groove of the hinged plate 52, and the end of the cross bar 55 away from the dryer 54 is fixedly installed on the inner wall of the square groove of the hinged plate 52. The air guide plate 56 is penetrated by a torsion spring and is hinged to the outer wall of the cross bar 55. The contact plate 57 is fixedly installed on the side of the air guide plate 56 close to the hollow cylinder 53. Through the above cooperation, the blowing amplitude of the dryer 54 is effectively changed to expand the blowing range, thereby improving the drying rate of the conveyor belt 33, and the flipped air guide plate 56 releases the relatively sealed environment at the bottom of the conveyor belt 33g, no longer blocking external dirt, while improving the circulation speed between the bottom of the conveyor belt 33 and the external air during the loading process, further improving the drying rate of the conveyor belt 33, preventing moisture from corroding the raw materials and reducing the performance.

[0026] When in use, when the U-shaped push plate 44 moves toward the center direction of the support platform 1, it pushes the sliding plate 51 to move synchronously along the top of the support platform 1. When the U-shaped push plate 44 is reset, the sliding plate 51 is reset by the spring force and reciprocates. The sliding plate 51 reciprocates and moves toward the center direction of the support platform 1 and resets, driving the hinged plate 52 to move synchronously. The hinged plates 52 on both sides are limited by the hollow cylinder 53 when they move synchronously toward the center of the support platform 1. At this time, the hinge axis of the hinged plate 52 starts to rotate and pushes the hollow cylinder 53 to move upward and resist the bottom of the conveyor belt 33 to deform. Through the above cooperation, the resistance force of the hollow cylinder 53 causes the top of the conveyor belt 33 to be slightly concave and deformed, thereby slightly changing the flat conveying posture of the top of the conveyor belt 33, preventing the top of the conveyor belt 33 from collapsing and deforming during a long period of feeding, while reducing the viscosity between the damp raw materials and the conveyor belt 33, thereby facilitating the separation of the raw materials. The top of the conveyor belt 33; the hinged plate 52 drives the air dryer 54 to move synchronously when it moves in an arc trajectory toward the center of the support platform 1. At the same time, the hinged plate 52 also drives the cross bar 55 and the air guide plate 56 to move synchronously. In the process of the air guide plate 56 driving the contact plate 57 to move synchronously, the contact plate 57 of each air guide plate 56 will contact the outer wall of the opposite air guide plate 56 to generate a resistance force. At this time, the hinge axis of the air guide plate 56 starts to rotate and flips along the outer wall of the cross bar 55. Through the above cooperation, the blowing amplitude of the air dryer 54 is effectively changed to expand the blowing range, thereby improving the air drying rate of the conveyor belt 33, and the flipped air guide plate 56 releases the relatively sealed environment at the bottom of the conveyor belt 33g, no longer blocking external dirt, while increasing the circulation speed between the bottom of the conveyor belt 33 and the external air during the loading process, further improving the air drying rate of the conveyor belt 33, preventing moisture from corroding the raw materials and reducing the performance.

[0027] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-adhesion device 6; The anti-adhesion device 6 includes a plurality of sliding blocks 61, a round rod 62 and a wave plate 63. The sliding blocks 61 are slidably installed on the outer wall of the hinged plate 52 by a spring on one side close to the air guide plate 56. Both ends of the round rod 62 are fixedly installed on the sliding block 61 on the side close to the center of the conveyor belt 33. The round rod 62 is located on the movement trajectory of the air guide plate 56. The wave plate 63 is fixedly installed on the outer wall of the sliding block 61 away from the air guide plate 56. Through the above coordination, the reciprocating motion of the wave plate 63 is used to disturb the airflow around the air guide plate 56, effectively extending the time for external air to enter the bottom range of the conveyor belt 33, that is, extending the drying time of the external airflow by the dryer 54, avoiding the external airflow carrying moisture and thereby aggravating the erosion of the conveyor belt 33, and preventing the raw materials from being further damp during the loading process, which may cause defects such as pores to appear on the surface of the finished product.

[0028] The anti-adhesion device 6 also includes an L-shaped plate 64, a limit frame 65, a rotating rod 66, a friction wheel 67 and a plurality of retractable brush plates 68. The bottom of the L-shaped plate 64 is hinged inside the sliding block 61, the limit frame 65 is fixedly installed on the outer wall of the L-shaped plate 64 on the side away from the wave plate 63, both ends of the rotating rod 66 are rotatably installed inside the limit frame 65, the friction wheel 67 passes through the inside and is fixedly installed on the outer wall of the rotating rod 66, and a plurality of retractable brush plates 68 are equidistant and fixedly installed on the outer wall of the rotating rod 66.

[0029] A torsion spring is arranged between the bottom of the L-shaped plate 64 and the sliding block 61, the outer wall of the friction wheel 67 contacts the bottom of the conveyor belt 33, and the outer wall of the telescopic end of the telescopic brush plate 68 contacts the bottom of the conveyor belt 33. Through the above cooperation, the telescopic end of the telescopic brush plate 68 is always pushed by the built-in spring to brush the bottom of the conveyor belt 33, so as to avoid that the telescopic end of the telescopic brush plate 68 is separated from the contact with the bottom of the conveyor belt 33 in some time periods due to the change of the angle of the L-shaped plate 64, and the brushing time of the telescopic brush plate 68 on the conveyor belt 33 is prevented from attenuating, and the outer wall of the conveyor belt 33 is prevented from having raw material residues attached to it during the transmission and feeding cycle, so as to prevent the raw material residues from being processed and produced simultaneously, thereby reducing the durability of the finished product.

[0030] When in use, the air guide plate 56 contacts the outer wall of the round rod 62 when it flips, thereby generating a resistance force. At this time, the round rod 62 generates a downward force under the push of the air guide plate 56, and the round rod 62 drives the sliding block 61 to slide downward along the outer wall of the hinged plate 52. Then, the sliding block 61 drives the round rod 62 to reset and repeat this process when the torsion spring is reset. The sliding block 61 reciprocates downward and during the reset process, it drives the wave plate 63 to move synchronously. Through the above cooperation, the reciprocating movement of the wave plate 63 is used to disturb the air flow around the air guide plate 56, effectively extending the time for external air to enter the bottom range of the conveyor belt 33, that is, extending the drying time of the external airflow by the air dryer 54, avoiding the external airflow carrying moisture and thereby aggravating the erosion of the conveyor belt 33, and preventing the raw materials from being further damp during the loading process, causing defects such as pores to appear on the surface of the finished product; the sliding block 61 slides back and forth downward and resets, driving the L-shaped plate 64 to move synchronously, and the L-shaped plate 64 drives the limit The frame 65 moves synchronously, the limit frame 65 drives the rotating rod 66 to move synchronously, and the rotating rod 66 drives the friction wheel 67 to move synchronously and rub along the bottom of the conveyor belt 33. The friction wheel 67 drives the rotating rod 66 to rotate through the friction force when it rotates. When the rotating rod 66 rotates, it drives the telescopic brush plate 68 to rotate. The top of the telescopic end of the telescopic brush plate 68 brushes the bottom of the conveyor belt 33. In the process that the telescopic brush plate 68 gradually moves away from the center of the conveyor belt 33, the above cooperation is used to promote the telescopic end of the telescopic brush plate 68 to always brush the bottom of the conveyor belt 33 through the push of the built-in spring, so as to avoid the telescopic end of the telescopic brush plate 68 from being separated from the bottom of the conveyor belt 33 in some time periods due to the change in the angle of the L-shaped plate 64, so as to prevent the telescopic brush plate 68 from brushing the conveyor belt 33 for a long time, and to avoid the outer wall of the conveyor belt 33 having raw material residues attached during the transmission and feeding cycle, so as to prevent the synchronous processing and production of the raw material residues, thereby reducing the durability of the finished product.
