Description

Technical Field

[0001] The utility model relates to the technical field of plastic strip cooling, in particular to a plastic strip cooling device for processing plastic particles. Background Art

[0002] In the process of plastic pellet processing, the plastic raw materials need to be put into the melting equipment, and the melting equipment forms the molten material, and the molten material is formed into continuous plastic strips under the action of the extruder. In order to accelerate the hardening of the plastic strips, the plastic strips are usually passed through cooling water continuously, and then quickly cooled and formed, so that the plastic strips can be cut into granules under the action of the pelletizer.

[0003] At present, there are many devices for cooling plastic strips, such as a Chinese patent with patent announcement number CN218366413U, which discloses a cooling water trough for injection molding strips, which includes a water trough body and a heat exchange shell arranged below the water trough body, the water trough body is provided with a plurality of first wire rollers and second wire rollers along the length direction, a water outlet device is arranged on one side of the water trough body, a heat exchange tube group is arranged in the heat exchange shell, the water inlet end of the heat exchange tube group is connected to the water trough body through a water pump, the water outlet end of the heat exchange tube group is connected to the water outlet device, and a blowing device for heat dissipation of the heat exchange tube group is arranged on the heat exchange shell, the first wire roller is installed on the water trough body through a swing bracket, and the second wire roller is installed on the water trough body through a shaft column. The cooling water trough has its own water circulation cooling system, which can cool down the water in the cooling water trough, and there is no need to add fresh cold water during use, and no need to cool with an external cooling water tower, and there is no limit on the installation position, and it can be moved, which is more practical than the traditional cooling water trough.

[0004] Although the device provided by the above patent can force the plastic strip to be immersed in cooling water through the wire roller to achieve cooling of the plastic strip, the position of the wire roller is fixed. Therefore, when the plastic strip is output from the extruder, the staff needs to hold the end of the plastic strip and pass it over multiple wire rollers in sequence. Because the wire roller is immersed in the cooling water, the staff's hands need to be immersed in the cooling water and hold the ends of the plastic strip alternately. This operation is relatively cumbersome. In addition, after the plastic strip is broken, the staff needs to hold the broken plastic strip and immerse it in hot water, which is very easy to cause damage. Utility Model Content

DETAILED DESCRIPTION

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like 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 a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following is a further description with reference to the accompanying drawings and specific embodiments: Example

[0028] like Figure 1 As shown, a plastic strip cooling device for plastic granule processing includes a cooling bin 1, two sets of drive components 4 and multiple sets of limiting components 3. The drive components 4 are arranged at both ends of the cooling bin 1, and the multiple sets of limiting components 3 are arranged on the inner side of the cooling bin 1 and partially immersed in cooling water. When the device is used to cool the plastic strip, the plastic strip output from the extruder is placed on the two sets of drive components 4 in sequence, and a longer plastic strip is left between the two sets of drive components 4, and then the multiple sets of limiting components 3 are buckled on the cooling bin 1, and the plastic strip is limited to be immersed in cooling water. Alternatively, when the device is used to cool the plastic strip, the plastic strip output from the extruder is first placed on a set of drive components 4, and the plastic strip is immersed in cooling water, and then a set of limiting components 3 is moved a certain distance and buckled on the cooling bin 1, and finally the plastic strip is placed on another set of drive components 4. This arrangement changes the current situation where the worker needs to pull the plastic strip due to the fixing of the wire roller, and bends over to put both hands alternately into the cooling water to immerse the plastic strip in the cooling water, which relatively reduces the complexity of the operation and avoids damage to the palm caused by the high temperature of the cooling water absorbing heat. In addition, the arrangement of the drive component 4 facilitates the control of the plastic strip to move along the length direction of the cooling bin 1 through its operation, which changes the current situation where the existing plastic strip cooling device lacks the power to move the plastic strip, and needs to use a pelletizer to pull the plastic strip to move, which easily leads to the breakage of the plastic strip.

[0029] like Figure 5 , Figure 6 As shown, in order to realize the movement of the plastic strip, the driving assembly 4 includes a driving roller 42 and an auxiliary roller 43. The end shaft of the driving roller 42 is sleeved with an end seat 45, which is installed on the cooling chamber 1, and two clamping plates 46 are symmetrically arranged on the top. The two clamping plates 46 can be set to be narrow at the upper end and wide at the lower end. The end of the central axis of the auxiliary roller 43 extends into the two clamping plates 46, so the clamping plates 46 stably clamp the central axis to make the auxiliary roller 43 work stably. At the same time, under the action of the auxiliary roller 43's own gravity, the auxiliary roller 43 can work stably relative to the driving roller 42. The driving roller 42 is connected to the output shaft of the motor 44, and the two driving rollers 42 are connected by the transmission belt 41. When the staff pulls the plastic strip to be supported on the driving assembly 4, the auxiliary roller 43 is lifted and separated from the restriction of the clamping plate 46, and the plastic strip is supported on the driving roller 42, and then the central axis of the auxiliary roller 43 is buckled in the clamping plate 46, and the auxiliary roller 43 contacts the plastic strip, limiting the contact between the plastic strip and the driving roller 42. Under the action of the motor 44, the driving roller 42 rotates, driving the plastic strip to move.

[0030] like Figure 7 , Figure 8As shown in the figure, in order to facilitate restricting the position of the plastic strip so that it can be stably immersed in the cooling water, the restricting assembly 3 includes a pressure rod 32 and two vertical plates 31. The vertical plates 31 are arranged in a hollow structure, and the top is arranged in a U-shaped structure. The inner side of the U-shaped top of the vertical plates 31 is provided with an anti-slip layer and is buckled on the side wall of the cooling bin 1. Therefore, when it is necessary to adjust the position of the restricting assembly 3, the staff can hold the vertical plates 31 and lift them to adjust the position. After adjusting the position, the top of the vertical plates 31 is buckled on the side wall of the cooling bin 1 again. The end of the pressure rod 32 is provided with a slot and a threaded groove, and a end plate 35 is arranged on the outer side of the end. A plug rod is fixedly arranged on the end plate 35 and penetrates through a bolt. The plug rod is inserted into the slot, and the bolt is threadedly inserted into the threaded groove. The two vertical plates 31 are respectively arranged at both ends of the pressure rod 32. A stepped groove 33 is arranged on the side of each of the two vertical plates 31 away from each other, and a supporting screw rod 34 penetrates through each vertical plate 31. The end of the pressure rod 32 extends into the vertical plate 31 and is supported on the supporting screw rod 34, and the edge of the end plate 35 extends into the stepped groove 33. The pressure rod 32 is supported on the supporting screw rod 34, and the supporting screw rod 34 can adjust its position relative to the vertical plate 31 according to requirements. Therefore, the staff can adjust the position of the pressure rod 32 at will to make it contact with the plastic strip, and the gravity of the pressure rod 32 itself is sufficient to offset the force exerted by the plastic strip on the pressure rod 32, so that the plastic strip can be stably immersed in the water. The setting of the end plate 35 facilitates restricting the position of the pressure rod 32 relative to the vertical plate 31 and prevents one end of the pressure rod 32 from tilting up and detaching from the vertical plate 31. Embodiment

[0031] As Figure 1 As shown in the figure, a plastic strip cooling device for plastic particle processing includes a cooling bin 1, two groups of driving assemblies 4 and multiple groups of restricting assemblies 3. The driving assemblies 4 are arranged at both ends of the cooling bin 1, and multiple groups of restricting assemblies 3 are arranged inside the cooling bin 1 and partially immersed in the cooling water. When using this device to cool the plastic strip, the plastic strip output from the extruder is successively supported on the two groups of driving assemblies 4, and a relatively long plastic strip is left between the two groups of driving assemblies 4. Then, multiple groups of restricting assemblies 3 are buckled on the cooling bin 1, and at the same time, the plastic strip is restricted from being immersed in the cooling water. Or, when using this device to cool the plastic strip, the plastic strip output from the extruder is first supported on one group of driving assemblies 4, and the plastic strip is immersed in the cooling water. At the same time, it moves a certain distance and one group of restricting assemblies 3 is buckled on the cooling bin 1. Finally, the plastic strip is supported on the other group of driving assemblies 4. This setting changes the situation that due to the fixation of the wire rollers, the staff needs to pull the plastic strip, and bend down and alternately put their hands into the cooling water to immerse the plastic strip in the cooling water. Relatively speaking, it reduces the operation complexity and avoids palm injuries caused by the increase in the temperature of the cooling water due to heat absorption. In addition, the setting of the driving assembly 4 facilitates controlling the movement of the plastic strip along the length direction of the cooling bin 1 through its operation, changing the situation that the existing plastic strip cooling device lacks the power for the plastic strip to move, and it is extremely easy to cause the plastic strip to break when pulling the plastic strip to move by means of a granulator.

[0032] As Figure 5 , Figure 6 shown, in order to realize the movement of the plastic strip, the driving assembly 4 includes a driving roller 42 and an auxiliary roller 43. A end seat 45 is sleeved on the end shaft of the driving roller 42. The end seat 45 is installed on the cooling bin 1, and two clamping plates 46 are symmetrically arranged above. The two clamping plates 46 can be set in a shape that is narrow at the upper end and wide at the lower end. The end of the central shaft of the auxiliary roller 43 extends into the two clamping plates 46. Therefore, the clamping plates 46 stably clamp the central shaft to enable the auxiliary roller 43 to work stably. At the same time, under the action of the self-gravity of the auxiliary roller 43, the auxiliary roller 43 can work stably relative to the driving roller 42. The driving roller 42 is connected to the output shaft of the motor 44, and the two driving rollers 42 are connected by a transmission belt 41. When the staff pulls the plastic strip and places it on the driving assembly 4, hold the auxiliary roller 43 to rise and break away from the restriction of the clamping plate 46, place the plastic strip on the driving roller 42, then buckle the central shaft of the auxiliary roller 43 into the clamping plate 46, and the auxiliary roller 43 contacts the plastic strip to limit the contact between the plastic strip and the driving roller 42. Under the action of the motor 44, the driving roller 42 rotates to drive the plastic strip to move.

[0033] As Figure 7 , Figure 8 shown, in order to facilitate restricting the position of the plastic strip so that it can stably sink into the cooling water, the restricting assembly 3 includes a pressure rod 32 and two vertical plates 31. The vertical plates 31 are set in a hollow structure, and the top is set in a U-shaped structure. The inner side of the U-shaped top of the vertical plates 31 is provided with an anti-slip layer and is buckled on the side wall of the cooling bin 1. Therefore, when it is necessary to adjust the position of the restricting assembly 3, the staff can hold the vertical plates 31 to rise and adjust the position, and the top of the vertical plates 31 after adjusting the position is buckled on the side wall of the cooling bin 1 again. The end of the pressure rod 32 is provided with a slot and a threaded groove, and a end plate 35 is arranged on the outer side of the end. A plug rod is fixedly arranged on the end plate 35 and penetrates through a bolt. The plug rod is inserted into the slot, and the bolt is threadedly inserted into the threaded groove. The two vertical plates 31 are respectively arranged at both ends of the pressure rod 32. A stepped groove 33 is arranged on the side of each vertical plate 31 away from each other, and a supporting screw 34 penetrates through each vertical plate 31. The end of the pressure rod 32 extends into the vertical plate 31 and is supported on the supporting screw 34, and the edge of the end plate 35 extends into the stepped groove 33. The pressure rod 32 is supported on the supporting screw 34, and the supporting screw 34 can adjust its position relative to the vertical plate 31 according to requirements. Therefore, the staff can freely adjust the position of the pressure rod 32 to make it contact the plastic strip, and the self-gravity of the pressure rod 32 is sufficient to offset the force exerted on the pressure rod 32 by the plastic strip, so that the plastic strip can stably sink into the water. The setting of the end plate 35 facilitates restricting the position of the pressure rod 32 relative to the vertical plate 31 and prevents one end of the pressure rod 32 from tilting and detaching from the vertical plate 31.

[0034] As Figure 1 , Figure 2 , Figure 3 As shown, in order to avoid the cooling water from heating up too fast, a blowing assembly 2 is also provided, which includes an air pump 21, a main pipe 22 and a plurality of shunt pipes 24. The main pipe 22 is connected to the output end of the air pump 21, and the plurality of shunt pipes 24 are evenly distributed on the side of the main pipe 22 and are connected to the main pipe 22 through a one-way valve 23. The shunt pipe 24 is provided with a plurality of air holes 25, and a baffle 26 and an internally threaded pipe 27 are provided at the end. A plurality of through holes 11 are provided at the bottom of the side wall of the cooling bin 1, and the end of the shunt pipe 24 is provided through the through hole 11, and the baffle 26 and the internally threaded pipe 27 are distributed on both sides of the side wall of the cooling bin 1. Under the action of the internally threaded pipe 27 and the baffle 26, the shunt pipe 24 is stably arranged in the cooling bin 1, and a sealing layer can be provided at the contact between the baffle 26 and the side wall of the cooling bin 1 to avoid leakage of cooling water. In addition, under the action of the air pump 21, gas can be input into different positions in the cooling water. During the rising process of the gas, the cooling water is driven to roll, and the heat of the cooling water is taken away, delaying the increase of the cooling water temperature. If the increase of the cooling water temperature is to be further suppressed, the air pump 21 can be connected to a cold air source (which can be set as an air conditioner, etc.) to take away the heat of the cooling water through the cold air.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
