Description

Technical Field

[0001] This utility model relates to the field of cooling technology in plastic production, and in particular to a cooling water tank for the production of plastic straws. Background Technology

[0002] The cooling water tank for plastic straws is a key piece of equipment in the straw production process. After the plastic straws are formed by the extruder, they need to be cooled rapidly to fix their shape and improve their physical properties (such as strength and toughness). The cooling water tank uses circulating cooling water to remove heat from the surface of the straws, thereby achieving uniform cooling.

[0003] In existing technology, plastic straws are generally produced by plastic hot melt extruders. The principle is to heat solid plastic to a molten state and then extrude it from the output end. At the moment of extrusion, the temperature of the plastic straw is high and it is relatively soft. At this time, it is necessary to cool and shape it in time. The common operation is: after manually holding the plastic straw with a tool, the plastic straw is placed on the guide roller, and then guided by the guide roller into the inlet end of the water tank for subsequent cooling and shaping.

[0004] However, in this existing technology, placing plastic straws onto the guide rollers manually can easily cause burns. In addition, plastic straws of various diameters are manufactured according to production needs, but the distance between the upper and lower guide rollers is fixed. When a larger diameter plastic straw passes between the two guide rollers, it is easy to be squeezed and deformed, resulting in substandard production quality and affecting the cooling progress.

[0005] Therefore, it is necessary to solve the above problems by using a cooling water tank for the production of plastic straws. Utility Model Content

[0012] Preferably, the guide assembly includes a guide wheel arranged in a vertical direction, with a lifting plate and a sliding plate rotatably connected to both ends of the guide wheel, an adjusting electric cylinder arranged between the lifting plates, and an auxiliary upright plate slidably connected to one end of the sliding plate.

[0013] Preferably, the adjusting electric cylinder and the auxiliary vertical plate are respectively fixedly installed on the cooling tank body, and a guide motor is installed on any of the sliding plates, the output end of the guide motor being fixedly connected to the side of the guide wheel.

[0014] The technical effects and advantages of this utility model are as follows: 1. In this utility model, by setting up a pulling component and a clamping component, the plastic straw body is pulled and placed in place instead of the manual pulling in the prior art, thus avoiding the problem of burns to personnel; the clamping component judges the current diameter of the plastic straw body and feeds it back to the remote control system in a timely manner. After receiving the signal, the remote control system controls the guide component to make appropriate adjustments, thereby avoiding the plastic straw body from being squeezed and deformed, which would lead to unqualified production quality and affect the cooling progress.

[0015] 2. In this utility model, by setting steel plates, translation plates, translation columns, and springs, when the clamping plate is close to the output end of the plastic hot melt machine, it can promptly determine whether the clamping plate has moved into place, whether it has clamped properly, and whether the diameter of the plastic straw body has changed. The signal is then promptly transmitted to the remote control system. The remote control system controls the pulling component, clamping component, and guiding component to operate or adjust in a timely manner based on the signal, thereby ensuring the stability of the plastic straw body during the pulling process, while preventing the plastic straw from being squeezed and deformed, ensuring production quality, and ensuring the cooling progress.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] To address the issues in existing technologies where manually placing plastic straws onto guide rollers can easily cause burns, and where the fixed spacing between the upper and lower guide rollers can lead to the deformation of larger diameter plastic straws as they pass between the rollers, resulting in substandard production quality and affecting the cooling process, the following embodiments are proposed.

[0020] This utility model provides, for example Figures 1 to 6 The cooling water tank shown includes a cooling tank body 1 installed on top of a support frame 2. The cooling tank body 1 contains cooling liquid, which is input from the inlet end and output from the outlet end. Therefore, the flow direction of the cooling liquid is consistent with the movement direction of the plastic straw body 8. Guide components 3 are provided at both ends of the cooling tank body 1, respectively at the inlet end and the outlet end. Guide components 4 and auxiliary rollers 5 are evenly arranged on the top of the cooling tank body 1. The auxiliary rollers 5 are configured in two layers, and the distance between the two layers is greater than the diameter of the plastic straw body 8. The specific function is to prevent the plastic straw body 8 from floating and to limit the vertical floating of the plastic straw body 8. The cooling tank body 1 is equipped with a pulling component 6 at the feeding end, and a clamping component 7 for clamping the plastic straw body 8 is provided on the pulling component 6. The plastic straw body 8 is extruded from the output end of the plastic hot melt machine 9. The output end of the plastic hot melt machine 9 is equipped with a mold with an output hole, and the plastic straw body 8 is extruded from the output hole. The cooling tank body 1 also includes a remote control system, which is connected to the guiding component 3, the guiding component 4, the pulling component 6 and the clamping component 7 via electrical signals.

[0021] In use, plastic granules are melted by the plastic hot melt machine 9 and then extruded from the mold at the output end to form the plastic straw body 8. At this time, the remote control system controls the pulling assembly 6 and the clamping assembly 7 to pull the plastic straw body 8 onto the guiding assembly 3.

[0022] By setting up the pulling component 6 and the clamping component 7, the plastic straw body 8 is pulled and placed in place instead of the manual pulling in the prior art, avoiding the problem of personnel being burned; the clamping component 7 determines the current diameter of the plastic straw body 8 and feeds it back to the remote control system in a timely manner. After receiving the signal, the remote control system controls the guide component 4 to make appropriate adjustments, thereby avoiding the plastic straw body 8 from being squeezed and deformed, which would lead to unqualified production quality and affect the cooling progress.

[0023] like Figures 4-5As shown, the clamping assembly 7 includes symmetrically arranged clamping plates 701. A recessed portion is provided on the side of the clamping plate 701 closest to the plastic hot melt machine 9. The recessed portion has a blind hole and an abutment point 707. A spring 703 and a translation column 704 are installed in the blind hole. A translation plate 705 is provided at the end of the translation column 704 away from the spring 703. A steel plate 706 is provided on the side of the translation plate 705 away from the translation column 704. A miniature pressure sensor is installed on the clamping plate 701, and the abutment point 707 is the pressing end of the miniature pressure sensor. A dual-output electric cylinder 702 is provided at the top of the clamping plate 701. When the steel plate 706 is not in contact with the mold... In the current state, the spring 703 is in a relaxed state, the translation plate 705 protrudes from the side of the clamping plate 701, and the translation plate 705 and the contact point 707 do not contact each other. When the steel plate 706 is in contact with the mold, the steel plate 706 and the translation plate 705 move towards the recess until the translation plate 705 contacts the contact point 707. The pulling assembly 6 includes a fixed right angle plate 601 fixedly installed on the side of the cooling tank body 1. A pulling electric cylinder 602 is provided on the top of the fixed right angle plate 601. A pulling horizontal plate 603 is fixedly provided at the output end of the pulling electric cylinder 602. The double output electric cylinder 702 is fixedly installed on the pulling horizontal plate 603.

[0024] In operation, the remote control system retracts the output end of the electric traction cylinder 602, thereby pulling the traction plate 603 closer to the plastic hot melt machine 9. This, in turn, moves the clamping plate 701 closer to the output end of the plastic hot melt machine 9, until the steel plate 706 abuts against the mold surface at the output end. The steel plate 706 then moves the translation plate 705 towards the recessed area, simultaneously compressing the spring 703 with the translation column 704, until the translation plate 705 contacts the contact point 707. This causes the miniature pressure sensor to be pressurized, and the miniature pressure sensor transmits the pressure signal to the remote control system. The remote control system receives the signal and determines that the clamping plate 701 has moved into position.

[0025] After receiving the signal, the remote control system stops the retraction of the output end of the pulling electric cylinder 602. Simultaneously, it retracts the output end of the dual-output electric cylinder 702, causing the two clamping plates 701 to move closer together until the pressure signal from the micro pressure sensor disappears. This indicates that the steel sheet 706 has entered the output hole on the mold. The spring 703 is then compressed and resets, causing the translation column 704 and translation plate 705 to move away from the contact point 707. Upon receiving the signal indicating the pressure signal has disappeared, the remote control system stops the retraction of the output end of the dual-output electric cylinder 702, and the two clamping plates 701 have clamped the plastic straw body 8 securely.

[0026] The remote control system controls the extension of the output end of the pull electric cylinder 602, thereby driving the clamping plate 701 and the plastic straw body 8 to move away from the plastic hot melt machine 9 through the pull plate 603 until the clamping plate 701 moves above the guide roller 301, and stops the extension of the output end of the pull electric cylinder 602. At the same time, the system controls the extension of the output end of the dual-output electric cylinder 702, driving the two clamping plates 701 to move away from each other, releasing the clamping of the plastic straw body 8, and placing the plastic straw body 8 on the guide roller 301.

[0027] By setting up steel plate 706, translation plate 705, translation column 704 and spring 703, when clamping plate 701 is close to the output end of plastic hot melt machine 9, it can promptly determine whether clamping plate 701 has moved into place, whether it has clamped properly, and whether the diameter of plastic straw body 8 has changed. It then promptly transmits the signal to the remote control system. The remote control system controls the pulling component 6, clamping component 7 and guiding component 4 to operate or adjust in a timely manner based on the signal, thereby ensuring the stability of the pulling process of plastic straw body 8, while avoiding the plastic straw from being squeezed and deformed, ensuring production quality, and ensuring the cooling progress.

[0028] like Figures 2-3 as well as Figure 6 As shown, the guiding component 3 includes a stepped guiding roller 301, with a rotating wheel 302 fixedly mounted at one end of the guiding roller 301. A transmission belt 303 is wound around the outer side of the rotating wheel 302. A guiding motor 304 is connected to any rotating wheel 302 and fixedly installed on the side of the cooling tank body 1. The guiding component 4 includes a guide wheel 401 arranged vertically. The liquid level of the cooling liquid is higher than the maximum height of the distance between the two guide wheels 401 to ensure that the plastic straw body 8 is completely immersed in the cooling liquid. A lifting plate 402 and a sliding plate 403 are rotatably connected to both ends of the guide wheel 401, respectively. An adjusting electric cylinder 404 is arranged between the lifting plates 402. An auxiliary upright plate 406 is slidably connected to one end of the sliding plate 403. The adjusting electric cylinder 404 and the auxiliary upright plate 406 are fixedly installed on the cooling tank body 1, respectively. A guiding motor 405 is installed on any sliding plate 403, and the output end of the guiding motor 405 is fixedly connected to the side of the guide wheel 401.

[0029] In use, the remote control system controls the simultaneous rotation of the guide motor 304 and the guide motor 405. The guide motor 304 drives the rotating wheel 302 to rotate, and simultaneously, the transmission belt 303 drives the other rotating wheels 302 to rotate, thereby driving the guide roller 301 to rotate. The guide roller 301 moves the plastic straw body 8 placed on it between the upper and lower guide wheels 401, that is, the plastic straw body 8 is below the surface of the cooling liquid. The guide motor 405 drives the guide wheel 401 to rotate, thereby moving the plastic straw body 8 towards the discharge end. During the movement, the flow of the cooling liquid helps the plastic straw body 8 move more stably towards the discharge end.

[0030] When it is necessary to produce plastic straw bodies 8 of different diameters, the staff needs to replace the mold at the output end of the plastic hot melt machine 9. After replacement, the clamping distance of the clamping plate 701 and the distance between the upper and lower guide wheels 401 need to be adjusted in time through the remote control system. If the staff forgets to adjust due to negligence, the plastic straw body 8 may be squeezed and deformed, which will require stopping the cooling for adjustment, thus reducing the cooling efficiency.

[0031] To solve the above problems, the distance between the clamping plates 701 can be determined based on the extension and retraction of the dual-output electric cylinder 702, thereby calculating the current diameter of the plastic straw body 8. The remote control system controls the extension and retraction of the output end of the electric cylinder 404 according to the calculated diameter, adjusting the distance between the two guide wheels 401 to a distance that adapts to the diameter of the plastic straw body 8, thus ensuring that the plastic straw body 8 can pass through smoothly.

[0032] The working principle of this utility model is as follows: First, a plastic straw is clamped, and the operator controls the plastic hot melt machine 9 to melt plastic granules, which are then extruded from the mold at the output end to form the plastic straw body 8. Simultaneously, the remote control system controls the output end of the pulling electric cylinder 602 to retract, thereby driving the pulling plate 603 closer to the plastic hot melt machine 9, and further driving the clamping plate 701 closer to the output end of the plastic hot melt machine 9, until the steel plate 706 abuts against the mold surface at the output end. The steel plate 706 drives the translation plate 705 to move towards the recessed part, and simultaneously drives the translation column 704 to compress the spring 703 until the translation plate 705 contacts the contact point 707, causing the miniature pressure sensor to be under pressure. The miniature pressure sensor transmits the pressure signal to the remote control system. The remote control system receives the signal and determines that the clamping plate 701 has moved into position. At this point, the output end of the control pull electric cylinder 602 stops retracting, and simultaneously, the output end of the control dual-output electric cylinder 702 retracts, causing the two clamping plates 701 to move closer to each other until the pressure signal from the micro pressure sensor disappears. This indicates that the steel sheet 706 has entered the output hole on the mold, the spring 703 is released from compression, and the translation column 704 and translation plate 705 are reset, with the translation plate 705 moving away from the contact point 707. After receiving the signal that the pressure signal has disappeared, the remote control system stops the output end of the control dual-output electric cylinder 702 from retracting, determining that the two clamping plates 701 have clamped the plastic straw body 8.

[0033] Secondly, the plastic straw is pulled. The remote control system controls the output end of the pulling electric cylinder 602 to extend, thereby pulling the clamping plate 701 and the plastic straw body 8 away from the plastic hot melt machine 9 through the pulling plate 603 until the clamping plate 701 moves above the guide roller 301, and stops the extension of the output end of the pulling electric cylinder 602. At the same time, the output end of the dual output electric cylinder 702 is controlled to extend, causing the two clamping plates 701 to move away from each other, releasing the clamping of the plastic straw body 8, and the plastic straw body 8 is placed on the guide roller 301.

[0034] Then, the plastic straw is conveyed. The remote control system controls the guide motor 304 and guide motor 405 to rotate simultaneously. The guide motor 304 drives the rotating wheel 302 to rotate, and at the same time, the transmission belt 303 drives the other rotating wheels 302 to rotate, thereby driving the guide roller 301 to rotate. The guide roller 301 moves the plastic straw body 8 placed on it to between the upper and lower guide wheels 401, that is, the plastic straw body 8 enters below the surface of the cooling liquid. The guide motor 405 drives the guide wheel 401 to rotate, thereby driving the plastic straw body 8 to pass through the guide wheel 401 and the auxiliary roller 5 in sequence, moving towards the discharge end. At the same time, the flow of the cooling liquid helps the plastic straw body 8 move more stably towards the discharge end.

[0035] Finally, after the plastic straw has cooled down, the guide motor 304 at the discharge end drives the rotating wheel 302 to rotate, thereby driving the guide roller 301 to carry away the cooling liquid from the plastic straw body 8 output between the last set of guide wheels 401 and transfer it to the next step.

[0036] It should be noted that when the extension / retraction amount of the output end of the dual-output electric cylinder 702 changes, it indicates that the diameter of the plastic straw body 8 changes. Specifically, the remote control system can determine the distance between the clamping plates 701 based on the extension / retraction amount of the dual-output electric cylinder 702, thereby calculating the current diameter of the plastic straw body 8. Based on the calculated diameter, the system controls the extension / retraction of the output end of the electric cylinder 404 to adjust the distance between the two guide wheels 401 to accommodate the diameter of the plastic straw body 8, thus ensuring that the plastic straw body 8 can pass smoothly and preventing deformation of the plastic straw.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
