Description

Technical Field

[0001] The invention relates to the technical field of plastic particle conveying, in particular to a conveyor for preventing plastic particles from sticking during production. Background Art

[0002] Plastic particles are processed by extrusion granulation process. The plastic particles cut by the cutter from the extruder need to be transported to the designated station through conveying equipment; Plastic particles are usually transported by screw conveyors. When conveying plastic particles, air cooling is usually used to dissipate the heat of the plastic particles. However, the screw conveyor pushes the plastic particles toward the target direction by the rotation of the spiral blades. The plastic particles accumulate at the bottom of the conveying chamber. Since the temperature of the newly processed plastic particles is relatively high, it is difficult to cool the accumulated plastic particles, especially the plastic particles in the middle layer. The plastic particles are prone to sticking to each other. If water cooling is used in the screw conveyor to dissipate the heat of the plastic particles, it can only be applied to the transportation of plastic particles with a density greater than that of water. Plastic particles with a density less than that of water will float on the surface of the cooling water, and it is difficult to push the plastic particles when the spiral blades rotate.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 11 The present invention provides a technical solution: a conveyor for preventing plastic particles from sticking during production, comprising a support seat 1, a conveying cylinder 2, a sealing head 3 and a pushing assembly 4; the conveying cylinder 2 is filled with cooling water and can swing on the support seat 1 by itself, and the cooling water used as a cooling medium can be replaced according to actual production to ensure that the cooling effect in the conveying cylinder 2 is optimal. During the swinging process of the conveying cylinder 2, the plastic particles are input from the highest point at the left end and output from the highest point at the right end after being cooled by the cooling water; the sealing head 3 is sealingly and slidably installed at both ends of the conveying cylinder 2 and can seal the end of the conveying cylinder 2 after the plastic particles are input and output; the pushing assembly 4 is arranged in the conveying cylinder 2 and close to the output end, and can push out the plastic particles after the output end of the conveying cylinder 2 rotates to the highest point.

[0018] When conveying plastic particles, the conveying cylinder 2 first rotates clockwise by a certain angle. When the left end of the conveying cylinder 2 swings to the highest point, the sealing head 3 on the left moves to the left, and the left end of the conveying cylinder 2 opens. The plastic particles cut by the cutter from the extruder enter the conveying cylinder 2 from the left end of the conveying cylinder 2, and the cooling water in the conveying cylinder 2 can cool the plastic particles; after the plastic particles enter the conveying cylinder 2, the sealing head 3 on the left moves to the right to close the opening at the left end of the conveying cylinder 2; then the conveying cylinder 2 rotates counterclockwise by a certain angle again until the right end of the conveying cylinder 2 rotates to the highest point, and then the sealing head 3 on the right can move to the right, the right end of the conveying cylinder 2 is opened, and the pushing assembly 4 pushes the cooled plastic particles in the conveying cylinder 2 from the right end to the collection or processing station; when the conveying cylinder 2 is conveying plastic particles with a density smaller than that of water, after the plastic particles enter the conveying cylinder 2 from the left end of the conveying cylinder 2, the plastic particles will float on the surface of the cooling water, and when the conveying cylinder 2 rotates counterclockwise, the cooling water will flow from left to right; Figure 8 and Fig. 9 As shown, Figure 8 and Fig. 9 The direction marked by the middle arrow is the flow direction of the plastic particles (with a lower density than water). The plastic particles can be fully contacted with the cooling water for cooling when moving from the left end to the right end. When the right end of the conveying cylinder 2 rotates to the highest point, the plastic particles will float on the right end of the conveying cylinder 2, and then the pushing mechanism can push the plastic particles out; when the conveying cylinder 2 is conveying plastic particles with a density greater than water, such as Fig.10 and Fig.11 As shown, Fig.10 The direction marked by the middle arrow is the flow direction of the plastic particles (with a density greater than that of water). After the particles enter from the left end of the conveying cylinder 2 in turn, the plastic particles will automatically slide to the right end of the conveying cylinder 2 under the action of gravity. During the process of the plastic particles sliding from the left end to the right end of the conveying cylinder 2, the cooling water can fully cool the plastic particles. When the conveying cylinder 2 starts to rotate counterclockwise, the pushing component 4 can block the plastic particles. After cooling, the plastic particles accumulated on the right end of the conveying cylinder 2 can no longer slide to the left end of the conveying cylinder 2. After the sealing head 3 on the right is opened, the pushing component 4 can push out the plastic particles accumulated on the right end of the conveying cylinder 2. It should be noted that, if Figure 7 As shown, in order to make the conveying continuity of the plastic particles better, at least two conveying cylinders 2 can be arranged on the support seat 1, and the two conveying cylinders 2 rotate in opposite directions. When one conveying cylinder 2 is feeding, the other conveying cylinder 2 is discharging. The present invention provides the conveying cylinder 2, the sealing head 3 and the pushing assembly 4, so that the conveying cylinder 2 can swing in a certain angle in a cycle. When the left end of the conveying cylinder 2 rotates to the highest point, the plastic particles can enter the conveying cylinder 2 from the left end of the conveying cylinder 2; the plastic particles with a density smaller than that of water can follow the liquid surface during the subsequent rotation of the conveying cylinder 2 and can be fully cooled in the conveying cylinder 2; the plastic particles with a density larger than that of water can slide from the left end of the conveying cylinder 2 to the right end in turn under the action of gravity and can be fully cooled. The pushing assembly 4 can block the plastic particles during the counterclockwise rotation of the conveying cylinder 2 to prevent the plastic from falling back to the left end; when the right end of the conveying cylinder 2 rotates to the highest point, the pushing assembly 4 can push the plastic particles out of the conveying cylinder 2; the plastic particles can be fully cooled during the conveying process and will not accumulate during cooling, which can better prevent the plastic particles from sticking; and the rotation angle of the conveying cylinder 2 can be adjusted according to actual needs, which can meet the input and output of plastic particles at different heights. The input and output of plastic particles can be at the same height or there can be a drop, which can better adapt to the transportation of plastic particles under different working conditions.

[0019] It should be noted that the circulation of cooling water in the conveying barrel 2 can be achieved by connecting a water inlet pipe and a water outlet pipe to the conveying barrel 2, and circulating the cooling water in the conveying barrel 2 through a water pump. Under the premise of good sealing, when the conveying barrel 2 is rotating to convey the plastic particles, there is very little overflow and loss of cooling water, which can better save water resources. Therefore, the function of the cooling water circulation is only to cool the cooling water that has heated up after absorbing heat again. The water pump does not need to convey a large amount of cooling water, and the power can be relatively small.

[0020] Specifically, Figure 2-Figure 4As shown, the pushing assembly 4 includes a guide rail 5, a first pushing plate 6, a second pushing plate 7, a third pushing plate 8, a switching mechanism and a driving mechanism; the guide rail 5 can slide along the length direction in the conveying cylinder 2 and is fixed with a spring for its reset; the first pushing plate 6 can slide along the height direction of the conveying cylinder 2 on the guide rail 5 and its height is less than the height of the conveying cylinder 2; the second pushing plate 7 is slidably installed on the first pushing plate 6 and can cooperate with the first pushing plate 6 to push plastic particles with a density less than water out of the conveying cylinder 2; the third pushing plate 8 is rotatably installed on the guide rail 5 and fits with the right side wall of the first pushing plate 6, and can cooperate with the first pushing plate 6 to push plastic particles with a density greater than water out of the conveying cylinder 2; the switching mechanism is arranged on the first push plate 6 and can adjust the position of the first push plate 6 when the conveying tube 2 conveys plastic particles of different densities; when the density of the plastic particles is less than that of water, the bottom end of the first push plate 6 fits with the bottom surface of the conveying tube 2; when the density of the plastic particles is greater than that of water, the top end of the first push plate 6 fits with the top surface of the conveying tube 2; the driving mechanism is arranged between the right sealing head 3 and the first push plate 6; during the opening process of the right sealing head 3, the driving mechanism can drive the first push plate 6 to cooperate with the second push plate 7 and the third push plate 8 to push the plastic particles out of the conveying tube 2; the first push plate 6, the second push plate 7 and the third push plate 8 are all provided with through holes that can penetrate water.

[0021] When the conveying cylinder 2 is conveying plastic particles with a density smaller than that of water, the first push plate 6, the second push plate 7 and the third push plate 8 are in Figure 3 and Figure 4 The state shown; during the counterclockwise rotation of the conveying cylinder 2, the plastic particles can flow from the gap above the first push plate 6 to the right end of the conveying cylinder 2; after the sealing head 3 on the right side is opened, the driving mechanism first drives the second push plate 7 to move upward to close the gap between the first push plate 6 and the conveying cylinder 2, and then the driving mechanism drives the first push plate 6, the second push plate 7 and the third push plate 8 to move rightward along the length direction of the conveying cylinder 2 to push the plastic particles out; when the conveying cylinder 2 is conveying plastic particles with a density greater than that of water, the switching mechanism can drive the first push plate 6 to move upward to a position in contact with the top surface of the conveying cylinder 2, at which time the first push plate 6, the second push plate 7 and the third push plate 8 are in Figure 5 It should be noted that, in this embodiment, the switching mechanism may be a linear drive mechanism, such as a cylinder, a linear motor, etc.; Fig.10 As shown, when the left end of the conveying cylinder 2 rotates to the highest point, the third push plate 8 rotates to the vertical position on the guide rail 5, and the bottom end of the first push plate 6 is in an open state. After the plastic particles enter from the left end of the conveying cylinder 2, they can slide down along the bottom surface of the conveying cylinder 2 to the right end of the conveying cylinder 2 under the action of gravity. When the conveying cylinder 2 rotates counterclockwise to the horizontal position and the right end of the conveying cylinder 2 rotates from the horizontal position to the highest point, the third push plate 8 always keeps in contact with the first push plate 6. At this time, the gap at the bottom end of the first push plate 6 is closed, and the cooled plastic particles can be Fig.11The plastic particles are piled up in the state shown, and then after the right sealing head 3 is opened, the driving mechanism can drive the first push plate 6, the second push plate 7 and the third push plate 8 to push the plastic particles out.

[0022] Specifically, Figure 2-Figure 5 , Figure 8-Figure 11 As shown, the driving mechanism includes a first traction rope 9, a wedge-shaped limit block 10 and a push rod 11; one end of the first traction rope 9 is fixedly connected to the second push plate 7, and the other end passes through the first push plate 6 and is fixedly connected to the sealing head 3 on the right side; the wedge-shaped limit block 10 is elastically slidably installed on the top of the conveying cylinder 2 and can limit the guide rail 5; the wedge-shaped limit block 10 is located directly above the first push plate 6; the push rod 11 is fixedly connected to the bottom of the wedge-shaped limit block 10 and the bottom end passes through the top of the conveying cylinder 2 and extends into the conveying cylinder 2; the push rod 11 is located directly above the second push plate 7.

[0023] After the right end of the conveying cylinder 2 rotates to the highest point, the sealing head 3 on the right side moves to the right side, which will drive one end of the first traction rope 9 to move to the right side synchronously; when conveying plastic particles with a density smaller than that of water, the end of the first traction rope 9 away from the sealing head 3 will first drive the second push plate 7 to move upward. When the second push plate 7 moves to the highest point to close the gap above the first push plate 6, the second push plate 7 will drive the push rod 11 to drive the wedge-shaped limit block 10 to move upward to cancel the limit on the guide rail 5, and then the first traction rope 9 can drive the first push plate 6, the second push plate 7, the third push plate 8 and the guide rail 5 to move along the length direction of the conveying cylinder 2 to push out the plastic particles; Fig. 9 As shown, since plastic particles with a density smaller than that of water will accumulate at the cooling water surface on the right side of the conveying cylinder 2, the second push plate 7 closes the gap above the first push plate 6 before pushing out the plastic particles, which can ensure that the plastic particles can be completely pushed out of the conveying cylinder 2; when the sealing head 3 moves to the left, the spring connected to the guide rail 5 drives the push assembly to move back into the conveying cylinder 2; and when conveying plastic particles with a density larger than that of water, after the first push plate 6 moves upward to fit the top surface of the conveying cylinder 2, the wedge-shaped limit block 10 will be pushed by the first push plate 6 to a state staggered with the guide rail 5, as shown in FIG. Fig.11 As shown, when the right end of the conveying cylinder 2 rotates to the highest point, the third push plate 8 automatically keeps the gap below the first push plate 6 closed. At this time, when the sealing head 3 on the right moves to the right, it can directly drive the first push plate 6, the second push plate 7, the third push plate 8 and the guide rail 5 to move outward to push out the plastic particles.

[0024] Specifically, Figure 2 , Figure 6 , Figure 8-Figure 11As shown, a guide mechanism for buffering and guiding plastic particles is also provided in the conveying cylinder 2; the guide mechanism includes a first guide plate 12, a second guide plate 13, a first motor 14 and a second traction rope 15; the first guide plate 12 is arranged vertically and can slide along the height direction of the conveying cylinder 2; the second guide plate 13 is arranged obliquely and can rotate in the conveying cylinder 2; the first motor 14 is installed on the outer wall of the conveying cylinder 2 and can drive the second guide plate 13 to rotate in the conveying cylinder 2; one end of the second traction rope 15 is fixedly connected to the first guide plate 12, and the other end is fixedly connected to the second guide plate 13; when the second guide plate 13 rotates, it can drive the first guide plate 12 to move upward through the second traction rope 15; the side walls of the first guide plate 12 and the second guide plate 13 are densely covered with bumps 16.

[0025] When the plastic particles move in the conveying cylinder 2, the first guide plate 12 and the second guide plate 13 can contact the plastic particles, and the first guide plate 12 and the second guide plate 13 can buffer and guide the flowing plastic particles. The plastic particles can be fully cooled before moving to the right end of the conveying cylinder 2, so that the plastic particles can be better cooled; at the same time, when a small amount of sticky plastic particles hit the bumps 16 on the first guide plate 12 and the second guide plate 13, the bumps 16 can separate the sticky plastic particles, which can better prevent the plastic particles from sticking during the conveying process; when conveying plastic particles of different densities, the positions of the first guide plate 12 and the second guide plate 13 can be adjusted by the first motor 14 and the second traction rope 15; Figure 8 and Fig. 9 As shown, when conveying plastic particles with a density smaller than that of water, the first guide plate 12 fits the bottom surface of the conveying cylinder 2, and the second guide plate 13, close to one end of the first guide plate 12, contacts the top surface of the conveying cylinder 2; Fig.10 and Fig.11 As shown, when conveying plastic particles with a density greater than that of water, the first guide plate 12 fits against the top surface of the conveying cylinder 2 , and the second guide plate 13 , close to one end of the first guide plate 12 , contacts the bottom surface of the conveying cylinder 2 .

[0026] Specifically, Figure 2 and Figure 4As shown, the switching mechanism includes a sleeve 17, a slide rod 18, a third traction rope 19, an insert block 20 and a drive block 22; the sleeve 17 can slide in the conveying cylinder 2 along the height direction of the conveying cylinder 2; the slide rod 18 is plugged into the sleeve 17 and fixedly connected to the first push plate 6; one end of the third traction rope 19 is fixedly connected to the sleeve 17, and the other end is fixedly connected to the second guide plate 13; when the second guide plate 13 rotates, the sleeve 17 can be driven to move upward by the third traction rope 19, so that the sleeve 17 drives the slide rod 18 and the first push plate 6 to move upward; the insert block 20 is elastically slidably connected to the guide rail 5 and can be plugged into the socket 21 opened on the first push plate 6 to fix the first push plate 6; the drive block 22 is fixedly connected to the end of the second guide plate 13 close to the first push plate 6 and can drive the insert block 20 to move out of the socket 21.

[0027] When the conveying cylinder 2 is conveying plastic particles with a density smaller than that of water, the pushing mechanism 4 is in Figure 2 When the conveying cylinder 2 needs to convey plastic particles with a density greater than that of water, the first motor 14 drives the second guide plate 13 to Figure 2 In the state shown, the second guide plate 13 rotates counterclockwise, and when the bottom end of the second guide plate 13 moves upward, the third traction rope 19 drives the sliding sleeve 17 to move upward synchronously, and the sliding sleeve 17 drives the first push plate 6 to move upward synchronously through the sliding rod 18; when the first push plate 6 moves upward until its top surface fits the top surface of the conveying cylinder 2, the plug block 20 is inserted into the plug hole 21 under the elastic force of the spring, and the plug block 20 cooperates with the plug block 21 to fix the first push plate 6; when the conveying cylinder 2 needs to convey plastic particles with a density smaller than water again, the first motor 14 drives the second guide plate 13 to rotate to Figure 2 At this time, the second guide plate 13 will drive the insert block 20 to move leftward through the drive block 22 to cancel the fixation of the first push plate 6, and then the first push plate 6 can move downward under its own gravity. Figure 2 The position shown; considering that plastic particles will produce debris during the pelletizing process, there will be certain debris in the cooling water in the conveying barrel 2. If the switching component is set as an electrical component (such as a cylinder, a linear motor, etc.), the debris and cooling water will cause the electrical component to reduce its accuracy or even be damaged after working for a long time in the conveying barrel 2; therefore, in this embodiment, the switching component adopts a purely mechanical structure, which can greatly improve the accuracy and service life of the switching component, and can make the conveying barrel 2 better suitable for the transportation of plastic particles of different densities.

[0028] Specifically, Figure 2 and Fig. 9 As shown, a fourth push plate 23 is rotatably installed on the inner wall of the right sealing head 3; when conveying plastic particles with a density smaller than that of water, the right sealing head 3 moves to the right, which drives the fourth push plate 23 to move to the right synchronously. The fourth push plate 23 can push the plastic particles accumulated on the cooling water surface to the right, and the second push plate 7 can be better closed.

[0029] Specifically, Figure 1 As shown, a first pulley 24 is fixedly connected to the rotating shaft of the conveying cylinder 2, the first pulley 24 is connected to the second pulley 26 through a transmission belt 25, the second pulley 26 is connected to the second motor 27, and the second motor 27 is fixedly connected to the support base 1; when the second motor 27 is working, the conveying cylinder 2 can be driven to swing through the second pulley 26, the transmission belt 25 and the first pulley 24.

[0030] Specifically, Figure 1 As shown, a cylinder 28 for driving the sealing head 3 to slide is fixedly connected to the outer wall of the conveying cylinder 2 ; the cylinder 28 can drive the sealing head 3 to move along the opening side wall of the conveying cylinder 2 .
