Description

Technical Field

[0001] The present invention relates to the technical field of recycled polyester chips, and particularly to a production and preparation device for recycled polyester chips. Background Art

[0002] Polyester (PET) has excellent physical and chemical properties. By recycling polyester, not only can the dependence on crude oil be reduced and petroleum resources be saved, but also the carbon dioxide emissions generated by recycling polyester are lower than those from producing polyester, which helps reduce greenhouse gas emissions, combat climate change, and can also promote the circular economy.

[0003] In the process of polyester recycling, the slicing process plays a crucial role. In this process, the recycled polyester is sent to a slicing machine or a granulating machine after reaction treatment and cut into granular products with specific lengths and shapes. To ensure the ease of processing of polyester chips in subsequent recycling and remanufacturing processes, there are certain requirements for the uniformity of polyester chips, and the size of the chips needs to be kept consistent and uniform.

[0004] Referring to the Chinese patent application document with the publication number CN118418324A, the publication date of August 2, 2024, and the name of "A Plastic Granulating Machine", it includes a diversion plate and a granulation chamber, and there are two feed rollers in the granulation chamber. When the device is running, the melt is extruded by a melt pump and sent to a casting head. After being extruded in multiple strands from the casting head, it is dispersed to form casting strips. The casting strips are first cooled by overflow water heat exchange and flow downward along the diversion plate. During the flow process, they are further cooled by sprayed water. The ends of the casting strips are pulled by the two feed rollers to make the casting strips extruded from the casting head uniform in thickness. There are moving knives and fixed knives for granulation in the granulation chamber.

[0005] In view of the above related technologies, when the casting strips are not cooled, the casting strips need to be pulled to be stretched and deformed into a certain thickness. However, due to the influence of temperature, material properties, and the slicing device, the casting strips may break during the movement, especially the not fully cooled casting strips. And the broken casting strips will lose the pulling force, resulting in uneven thickness of the casting strips extruded from the casting head. Also, the position of the casting strips may shift during the movement, which may cause multiple casting strips to entangle with each other, all of which affect the uniformity of polyester chips. Therefore, to ensure the uniformity of polyester chips, it is necessary to remove the deformed casting strips that have lost traction as waste, and it is necessary to make the ends of the casting strips re-enter between the two feed rollers for pulling. Summary of the Invention

[0006] In view of this, the present invention provides a production and preparation device for recycled polyester chips, aiming to solve the technical problem in the prior art that it is necessary to remove waste and re-pull the casting strips after the casting strips break.

[0007] To solve the above technical problems, a production and preparation device for recycled polyester chips provided by the present invention adopts the following technical solutions: A production and preparation device for recycled polyester chips includes a cooling pool located below the extrusion casting head. A conveyor belt is provided at the right end of the cooling pool. An inlet roller is provided above the right end of the conveyor belt. A slicing chamber is provided on the right side of the conveyor belt;

[0008] A rotating roller is provided above the left end of the cooling pool. A plurality of flow guiding plates arranged along the axial direction of the rotating roller are rotatably sleeved on the rotating roller. A rotating member for controlling the rotation of the flow guiding plate around the central axis of the rotating roller is provided on the cooling pool. The left end of the flow guiding plate is connected with a water outlet pipe. A concave flow guiding groove one is provided on the top surface of the flow guiding plate;

[0009] A fixing plate is connected to the cooling pool. A plurality of guiding grooves arranged along the axial direction of the rotating roller are opened on the bottom surface of the fixing plate. The guiding grooves extend vertically and can allow the flow guiding plate to rotate;

[0010] A blanking roller is rotatably connected inside the cooling pool. A gap for the casting strip on the flow guiding plate to pass through is left between the blanking roller and the inner bottom wall of the cooling pool;

[0011] A cutting knife is connected inside the cooling pool. The cutting knife is connected to the right end of the flow guiding plate;

[0012] An auxiliary belt is provided above the cooling pool. The bottom surface of the auxiliary belt is matched with the top surface of the conveyor belt to convey the casting strip to the right.

[0013] By adopting the above technical solutions, when the device operates, the flow guiding plate rotates to the lower part. The front half of the casting strip moves along the flow guiding plate. The right end of the casting strip is located on the conveyor belt. The casting strip located on the conveyor belt has been cooled. The part of the casting strip close to the conveyor belt is suspended in the guiding groove.

[0014] When the casting strip suddenly breaks, the part of the casting strip located on the conveyor belt continues to be conveyed along the conveyor belt and sliced. The other part of the casting strip drops downward onto the flow guiding plate. The casting head continuously extrudes. The casting strip moves downward until the right end of the casting strip enters between the blanking roller and the cooling pool. The blanking roller and the cooling pool cooperate to continuously provide traction for the casting strip, so that the casting strip extruded from the casting head is stretched into a certain thickness. The flow guiding plate rotates upward. The cutting knife cooperates with the flow guiding plate to cut off the casting strip. The un-stretched casting strip waste is cut off and drops into the cooling pool. The casting strip on the flow guiding plate is the part stretched by the blanking roller. The flow guiding plate continues to move upward and sends the end of the stretched casting strip between the conveyor belt and the auxiliary belt. The auxiliary belt and the conveyor belt cooperate to traction and convey the casting strip. Solve the problem that it is necessary to remove waste and re-traction after the casting strip breaks. The device can perform continuous operation and reduce the workload of workers.

[0015] A fixed plate and a guide groove are provided to separate multiple casting belt strips, and the situation where multiple casting belt strips are entangled with each other is avoided as much as possible. The problem of entanglement between multiple casting belt strips is solved, and in cooperation with the diversion plate, it is ensured that the diversion plate can receive the corresponding casting belt strip, facilitating re-traction.

[0016] Optionally, two partitions arranged in the front-back direction are connected to the left end of the diversion plate, and the two partitions gradually move away from each other upward from bottom to top.

[0017] By adopting the above technical solution, the two partitions are used to guide the casting belt strips extruded at the casting head to enter into the first diversion groove. The partitions are inclined, which helps to separate multiple casting belt strips and guide the casting belt strips.

[0018] Optionally, a second diversion groove protruding upward is provided on the top wall of the guide groove.

[0019] By adopting the above technical solution, the second diversion groove cooperates with the first diversion groove to limit the movement direction of the casting belt strip in the first diversion groove and reduce the occurrence of the situation where the casting belt strip deviates.

[0020] Optionally, the auxiliary belt is inclined downward from left to right.

[0021] By adopting the above technical solution, the auxiliary belt is inclined, which facilitates the end of the casting belt strip to enter between the bottom of the auxiliary belt and the top of the conveyor belt, and is beneficial to avoiding structural conflicts between the fixed plate, the diversion plate and the auxiliary belt as much as possible.

[0022] Optionally, a pressing rod for guiding the lower belt of the auxiliary belt is rotatably connected in the cooling pool.

[0023] Optionally, anti-slip lines extending along the axial direction of the blanking roller are fixedly connected to the circumferential side wall of the blanking roller, and multiple anti-slip lines are arranged circumferentially along the blanking pipe.

[0024] By adopting the above technical solution, it is beneficial for the blanking roller to provide traction force to the casting belt strip and make the casting belt strip move to the right.

[0025] Optionally, a drying member is provided above the conveyor belt.

[0026] By adopting the above technical solution, the casting belt strip is dried and then sliced. There is no need to dry it after slicing, and drying before slicing is relatively simple. If drying is carried out after slicing, additional stirring devices and drying devices need to be provided to dry the slices, which is relatively complex.

[0027] Optionally, the drying member includes a drying chamber, a hair dryer and a heating pipe, and the air blown out by the hair dryer is blown to the upper part of the conveyor belt after being heated by the heating pipe.

[0028] In summary, the present invention includes the following beneficial technical effects:

[0029] The cutter cooperates with the guide plate to cut the cast strip, wherein the unstretched cast strip waste is cut off and falls into the cooling pool. The cast strip on the guide plate is the part stretched by the unloading roller. The guide plate continues to move upward to feed the end of the stretched cast strip into between the conveyor belt and the auxiliary belt. The auxiliary belt cooperates with the conveyor belt to pull and transport the cast strip, solving the problem of removing waste and re-pulling after the cast strip breaks. The device can perform continuous operation and reduce the workload of workers; fixed plates and guide grooves are set to separate multiple cast strips to avoid the entanglement of multiple cast strips as much as possible, solve the problem of entanglement between multiple cast strips, and cooperate with the guide plate to ensure that the guide plate can take over the corresponding cast strips for easy re-pulling;

[0030] 2. The two partitions are used to guide the cast strips extruded from the cast strip head so that they enter the guide groove 1. The partitions are inclined to help separate multiple cast strips and guide the cast strips.

Detailed implementation manners

[0043] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0044] The following will further describe the present invention in detail with reference to the attached Figure 1 - attached Figure 8 drawings.

[0045] The embodiment of the present invention discloses a production preparation device for recycled polyester chips. Referring to Figures 1 to 8 , a production preparation device for recycled polyester chips includes an extruder 11 equipped with a casting head 1, a cooling pool 2, a slicing assembly 3, an auxiliary assembly 4 and a drying member 5. The recycled polyester material is added into the extruder 11, and the extruder 11 extrudes the molten recycled polyester material from the casting head 1, extruding a plurality of casting strips to be cooled. When the device is just started, the end of the casting strip needs to be guided so that the right end of the casting strip is pulled, and the casting strip is stretched into a long strip. During the stretching process, the cooling pool 2 cools the casting strip, and the slicing assembly 3 slices the cooled casting strip into particles. The auxiliary assembly 4 is arranged at the cooling pool 2. The auxiliary assembly 4 is used to remove the thicker casting strip that has not been stretched as waste when the casting strip breaks accidentally, and can provide traction for the casting strip again, and send the end of the stretched casting strip into the slicing assembly 3, so that the device runs continuously and can improve the consistency of the product. The drying member 5 is used to dry a plurality of casting strips on the conveyor belt 31.

[0046] Referring to Figure 1 and Figure 2, the cooling pool 2 is filled with a liquid for cooling the cast strip, such as water.

[0047] Referring to Figure 2 and Figure 3 , the slicing assembly 3 includes a conveyor belt 31, a feeding roller 32 and a slicing chamber 33.

[0048] The conveyor belt 31 is arranged at the right end of the cooling pool 2, the feeding roller 32 is arranged above the right end of the conveyor belt 31, the feeding roller 32 corresponds to the belt driving roller on the right side of the conveyor belt 31, the feeding roller 32 cooperates with the conveyor belt 31 to provide traction for the cast strip and make the cast strip move to the right. The slicing chamber 33 is located on the right side of the conveyor belt, and the cast strip enters the slicing chamber 33 for slicing.

[0049] Referring to Figure 2 , further, a first gear is sleeved on the belt driving roller on the right side of the conveyor belt 31, a second gear is sleeved on the feeding roller 32, and the first gear meshes with the second gear, so that the feeding roller 32 rotates actively, which is beneficial to improving the stability of the device. By setting the first gear and the second gear, when the conveyor belt 31 is driven by an external rotating source, such as a rotating motor, the feeding roller 32 can also be driven to rotate, which is convenient for use.

[0050] Referring to Figure 5 , Figure 6 and Figure 7 , the auxiliary assembly 4 includes a rotating roller 41, a guide plate 42, a rotating member 43, a water outlet pipe 44, a fixing plate 45, a feeding roller 46, a cutting knife 47 and an auxiliary belt 48.

[0051] The rotating roller 41 is arranged above the left end of the cooling pool 2, the rotating roller 41 is fixedly connected to the cooling pool 2, and the axial direction of the rotating roller 41 extends in the front-rear direction. There are multiple guide plates 42, and the multiple guide plates 42 are arranged in sequence along the axial direction of the rotating roller 41. The left end of the guide plate 42 is sleeved on the rotating roller 41, the guide plate 42 rotates around the central axis of the rotating roller 41, and the guide plate 42 is inclined downward from left to right. The rotating member 43 is arranged between the cooling pool 2 and the guide plate 42 for controlling the rotation of the guide plate 42. The water outlet pipe 44 is connected to the left end of the guide plate 42, and a concave guide groove 421 is formed on the top surface of the guide plate 42.

[0052] The cast strip falls onto the guide plate 42, the water outlet pipe 44 discharges water, the water flow drives the cast strip to move to the right and cools the cast strip at the same time. By setting the guide groove 421, it is helpful to limit the cast strip and reduce the occurrence of the cast strip deviation.

[0053] Referring to Figure 5, specifically, the rotating member 43 includes a plurality of rotating motors, which correspond to the plurality of flow guiding plates 42 one by one. One end of the rotating motor is hinged to the cooling pool 2, and the output end of the rotating motor is hinged to the bottom surface of the left end of the flow guiding plate 42. By starting the rotating motor, the overall length of the rotating motor and its output end is changed, thereby driving the flow guiding plate 42 to rotate.

[0054] Refer to Figure 5 , further, two partition plates 422 are connected to the left end of the flow guiding plate 42. The two partition plates 422 are arranged in the front-rear direction. The two partition plates 422 are both inclined, and the two partition plates 422 gradually move away from each other upward, that is, the distance between the two partition plates 422 gradually increases upward. This is beneficial to guiding the cast strip extruded at the casting head 1 so that it falls on the flow guiding plate 42.

[0055] The fixing plate 45 is fixedly connected to the cooling pool 2. The fixing plate 45 is located above the flow guiding plate 42. A plurality of guiding grooves 451 are formed on the bottom surface of the fixing plate 45. The plurality of guiding grooves 451 are arranged in sequence along the axial direction of the rotating roller 41. The guiding grooves 451 are for the flow guiding plate 42 to rotate. By providing the fixing plate 45 and the guiding grooves 451, multiple cast strips are separated, and the situation where multiple cast strips are entangled with each other is avoided as much as possible. The problem of entanglement between multiple cast strips is solved. In cooperation with the flow guiding plate 42, it is ensured that the flow guiding plate 42 can receive the corresponding cast strip, which is convenient for re-traction.

[0056] Refer to Figure 6 , further, a second flow guiding groove 452 protruding upward is formed on the top wall of the guiding groove 451. The second flow guiding groove 452 cooperates with the first flow guiding groove 421 to limit the movement direction of the cast strip in the first flow guiding groove 421, and further reduce the occurrence of the situation where the cast strip deviates.

[0057] Refer to Figure 7 and Figure 8 , the blanking roller 46 is rotatably connected to the inside of the cooling pool 2, and the blanking roller 46 is driven to rotate by an external rotating source, such as a rotating motor. There is a gap between the blanking roller 46 and the bottom wall inside the cooling pool 2 for the cast strip on the flow guiding plate 42 to pass through. When the cast strip breaks accidentally, the flow guiding plate 42 receives the cast strip, and the cast strip moves along the flow guiding plate 42 until the end of the cast strip enters between the blanking roller 46 and the cooling pool 2, and the blanking roller 46 provides a new traction force for the cast strip.

[0058] Refer to Figure 8 , further, anti-slip lines extending along the axial direction of the blanking roller 46 are fixedly connected to the circumferential side wall of the blanking roller 46. The plurality of anti-slip lines are arranged along the circumferential direction of the blanking pipe. The friction between the blanking roller 46 and the cast strip is increased, which is beneficial for the blanking roller 46 to provide a traction force for the cast strip and make the cast strip move to the right.

[0059] Refer to Figure 7 andFigure 8 The cutting knife 47 is fixedly connected to the inner wall of the cooling pool 2, and the cutting knife 47 is in contact with the right end of the flow guide plate 42. When the flow guide plate 42 rotates upward, the cutting knife 47 cooperates with the flow guide plate 42 to cut off the strip, completing the removal and blanking of the waste.

[0060] Refer to Figure 7 As shown in the figure, the auxiliary belt 48 is arranged at the right end of the cooling pool 2, and the auxiliary belt 48 is arranged above the conveyor belt 31. The bottom surface of the auxiliary belt 48 cooperates with the top surface of the conveyor belt 31 to convey the strip to the right. When the flow guide plate 42 rotates upward and sends the right end of the strip to the conveyor belt 31, since the length of the strip on the conveyor belt 31 is short at this time, the strip may fall. By setting the auxiliary belt 48, the auxiliary belt 48 can also provide traction for the strip and make the strip move to the right, completing the continuation of the strip.

[0061] Refer to Figure 7 Furthermore, the auxiliary belt 48 is arranged obliquely downward from left to right, and a pressing rod for guiding the lower belt of the auxiliary belt 48 is rotatably connected in the cooling pool 2. The inclined arrangement of the auxiliary belt 48 facilitates the end of the strip to enter between the auxiliary belt 48 and the conveyor belt, which is beneficial to avoiding structural conflicts between the fixing plate 45, the flow guide plate 42 and the auxiliary belt 48 as much as possible.

[0062] Refer to Figure 2 Furthermore, a drying member 5 is arranged above the conveyor belt 31.

[0063] Specifically, the drying member 5 includes a drying chamber 51, a hair dryer 52 and a heating pipe. The air blown out by the hair dryer 52 is blown above the conveyor belt 31 after being heated by the heating pipe.

[0064] The strip is dried before being sliced, so there is no need to dry it after slicing, and drying before slicing is relatively simple. If it is dried after slicing, additional stirring devices and drying devices are required to dry the slices, which is more complicated.

[0065] The implementation principle of the recycling polyester chip production and preparation device according to the embodiment of the present invention is as follows:

[0066] The extruder 11 operates, and the casting head 1 continuously extrudes multiple strips.

[0067] The casting belt strip falls to the left end of the diversion plate 42. The partition plate 422 at the left end of the diversion plate 42 guides the falling direction of the casting belt strip, and multiple casting belt strips correspond to multiple diversion plates 42 one by one. The water outlet pipe 44 continuously discharges water to cool the casting belt strips on the diversion plate 42. When the device is initially operated, the casting belt strips need to be guided between the conveyor belt 31 and the auxiliary belt 48, and further guided between the feeding roller 32 and the conveyor belt 31. The slicing chamber 33 slices the casting belt strips. After the guiding is completed, the diversion plate 42 rotates downward. At this time, the left part of the casting belt strip is on the diversion plate 42, the right part of the casting belt strip is on the conveyor belt 31, and the middle part of the casting belt strip is suspended in the guiding groove 451. The liquid in the cooling pool 2 soaks the casting belt strip and cools the casting belt strip.

[0068] During the operation of the device, one or more casting belt strips may be accidentally broken. Taking one break as an example for illustration. When the casting belt strip is accidentally interrupted, the cooled casting belt strip is on the conveyor belt 31, and the conveyor belt 31 continues to transport and slice it.

[0069] For the uncooled part of the casting belt strip, the casting belt strip drops downward onto the diversion plate 42. With the continuous extrusion of the casting belt strip and the scouring action of the water flow at the water outlet pipe 44, the casting belt strip moves downward until the right end of the casting belt strip enters between the blanking roller 46 and the cooling pool 2. The blanking roller 46 rotates and provides traction for the casting belt strip, so that the casting belt strip extruded from the casting head 1 will be tractionally stretched into a long strip during the subsequent movement. The corresponding rotating part 43 controls the diversion plate 42, and the diversion plate 42 rotates upward until the cutting knife 47 cooperates with the diversion plate 42 to cut off the casting belt strip, cutting off the thicker un-stretched casting belt strip on the casting belt strip as waste. The diversion plate 42 continues to move upward, sending the end of the thinner stretched casting belt strip between the conveyor belt 31 and the auxiliary belt 48, completing the removal of the casting belt strip waste and the continuation of the casting belt strip. It is beneficial to improve the consistency of the sliced products and reduce the difficulty and workload of subsequent screening.

[0070] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
