Description

Technical Field

[0001] The present invention relates to the technical field of film pressing cooling, and specifically provides a multi-stage gradient cooling wheel set. Background Art

[0002] The main component of PVC is polyvinyl chloride. By adding plasticizers to polyvinyl chloride, soft PVC films can be blown by the blow molding method. Transparent and semi-transparent films can be made according to different stabilizers used. Due to its good flexibility, transparency and barrier properties, PVC packaging films are widely used in many fields such as food and daily necessities.

[0003] In the production and processing of PVC packaging films, the cooling process is a crucial link. In the Chinese Patent Publication No. CN222451066U, a PVC film shaping and cooling device is disclosed, which includes a base, a rotating bracket, a rotating motor, a rotating roller, a support member, a heat conducting plate, heat dissipation fins, a lifting bracket, a pressing plate and a locking knob; the top of the base is connected to the rotating bracket; the top of the rotating bracket is connected to the rotating motor; the output end of the rotating motor is in transmission connection with the rotating roller; the side of the rotating roller is rotatably connected to the side of the rotating bracket; a transmission support structure for transmission tensioning is provided on the top of the base; the top of the base is connected to the support member; the top of the support member is connected to the heat conducting plate; the bottom of the heat conducting plate is connected to multiple groups of heat dissipation fins; the top of the base is connected to the lifting bracket; through this device, the present invention can effectively improve the cooling speed of the film raw material, and at the same time, the combination of the heat conducting plate and the heat dissipation fins can quickly conduct the temperature, avoiding heat accumulation on the top of the heat conducting plate. At the same time, the pressing plate can perform pressing processing during the transmission of the film raw material.

[0004] The above patent cools the PVC film by contacting the PVC film with the heat conducting plate and conducting the heat on the heat conducting plate to multiple groups of heat dissipation fins for dissipation. However, when the PVC film contacts the heat conducting plate and generates relative movement, it is extremely easy for the PVC film to deform during the sliding friction process, affecting the final forming effect and basic quality of the product. Moreover, when the heat dissipation fins are cooled by air blowing, due to the disordered flow of air, uneven heat dissipation will occur. Summary of the Invention

[0026] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] In the present application, the cooling wheel is in contact with the material, and the cooling wheel rotates, that is, there is no relative sliding between the material and the cooling wheel. Compared with the contact sliding between the PVC film and the heat conducting plate, the friction force received by the material during the cooling process can be greatly reduced, and the deformation caused by friction can be reduced. Moreover, the cooling wheel in the present application has a hollow structure, and a coolant is poured into the hollow cooling wheel, so that the coolant circulates to take away the heat, ensuring the uniform temperature of the cooling wheel and avoiding the poor final forming effect of the product due to uneven heat dissipation;

[0028] Multiple groups of cooling wheels are provided in the present application, and the multiple groups of cooling wheels gradually cool down the material, and can quickly reduce the temperature of the material to a suitable temperature. When a single group of cooling wheels is set, in order to ensure the contact time between the cooling wheel and the material, it is necessary to slow down the rotation speed of the cooling wheel or increase the size of the cooling wheel. However, slowing down the rotation speed of the cooling wheel will reduce the cooling efficiency, and increasing the size of the cooling wheel will cause the cooling equipment to be huge. Therefore, the cooling wheels in the present application are set in multiple groups, and the equipment volume can still be maintained small while ensuring the cooling efficiency, that is, without reducing the rotation speed of the cooling wheel;

[0029] The coolant in the previous group of cooling wheels is in a mixed state of the coolant in the next group of cooling wheels and the coolant in the main inlet cooling pipe, and its temperature is lower than the temperature of the coolant in the next group of cooling wheels, that is, the temperature of the coolant in the cooling wheel decreases sequentially from the first group to the last group, and can sequentially reduce the temperature of the material, avoiding too large temperature mutation resulting in increased internal stress, deformation or rupture of the material, etc.;

[0030] At the same time, compared with all cooling wheels being provided with coolant by the main inlet cooling pipe, the setting of part of the coolant flowing through multiple groups of cooling wheels in the present application will effectively reduce the flow rate of the coolant in the main inlet cooling pipe, reduce the load of the coolant circulation, and save energy consumption.

They are merely used to distinguish protection components or operations described with the same technical terms, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. Additionally, the technical solutions and technical features between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0042] Embodiment 1

[0043] Please refer to Figure 1 、 Figure 2, A multi-stage gradient cooling wheel group, including a cooling wheel 1, with several sets of the cooling wheels 1 provided. The cooling wheel 1 that finally contacts the material 40 to be cooled is set as the last group, and the cooling wheel 1 that first contacts the material 40 to be cooled is set as the first group. The cooling wheel 1 is of a hollow structure, and interfaces for inlet and outlet of coolant are provided at both ends of the cooling wheel 1. One end of the cooling wheel 1 is connected to an auxiliary inlet cooling pipe 5, and the auxiliary inlet cooling pipes 5 are all connected to a main inlet cooling pipe 3. The other ends of the cooling wheels 1 except the first group are connected to the auxiliary inlet cooling pipe 5 of the previous group through an auxiliary return cooling pipe 6, and the other end of the first group of the cooling wheels 1 is connected to a main return cooling pipe 4 through an auxiliary return cooling pipe 6.

[0044] A one-way valve 7 is provided on the auxiliary return cooling pipe 6 connected to the auxiliary inlet cooling pipe 5 of the previous group.

[0045] The cooling wheel 1 is rotatably connected to a bracket 2.

[0046] The working principle and beneficial effects of the above solution:

[0047] In this application, the cooling wheel 1 is attached to the material 40 (PVC film), and the cooling wheel 1 rotates, that is, there is no relative sliding between the material 40 and the cooling wheel 1. Compared with the contact and sliding between the PVC film and the heat-conducting plate, the friction force received by the material 40 during the cooling process can be greatly reduced, and the deformation caused by friction can be reduced. Moreover, the cooling wheel 1 in this application is of a hollow structure, and coolant is poured into the hollow cooling wheel 1, so that the coolant circulates to take away the heat, ensuring the uniform temperature of the cooling wheel 1 and avoiding the poor final forming effect of the product due to uneven heat dissipation.

[0048] In this application, several sets of cooling wheels 1 are provided, and the multi-group cooling wheels 1 gradually cool the material 40, and can quickly reduce the temperature of the material 40 to a suitable temperature. When a single set of cooling wheels 1 is set, to ensure the contact time between the cooling wheel 1 and the material 40, it is necessary to slow down the rotation speed of the cooling wheel 1 or increase the size of the cooling wheel 1. However, slowing down the rotation speed of the cooling wheel 1 will reduce the cooling efficiency, and increasing the size of the cooling wheel 1 will cause the cooling equipment to be large. Therefore, in this application, the cooling wheels 1 are set in multiple groups, and the equipment volume can still be maintained small while ensuring the cooling efficiency, that is, without reducing the rotation speed of the cooling wheel 1.

[0049] The coolant in the previous group of cooling wheels 1 is in a mixed state of the coolant in the next group of cooling wheels 1 and the coolant in the main inlet cooling pipe 3, and its temperature is lower than the temperature of the coolant in the next group of cooling wheels 1, that is, the temperature of the coolant in the cooling wheel 1 decreases sequentially from the first group to the last group, and can sequentially reduce the temperature of the material 40, avoiding the increase of internal stress, deformation or rupture of the material 40 caused by too large temperature mutation.

[0050] Meanwhile, compared with all the cooling wheels 1 being supplied with coolant by the main inlet cooling pipe 3, the arrangement where part of the coolant flows through multiple groups of cooling wheels 1 in sequence in this application can effectively reduce the flow rate of the coolant in the main inlet cooling pipe 3, reduce the load of coolant circulation, and save energy consumption.

[0051] Embodiment 2

[0052] Please refer to Figure 3 、 Figure 4 Based on Embodiment 1, the auxiliary inlet cooling pipe 5 and the auxiliary return cooling pipe 6 are connected through a connector 8. The connector 8 includes a connector housing 9. The connector housing 9 is a tubular structure. An opening is provided on the side wall of the connector housing 9. The opening on the side wall of the connector housing 9 is connected to an adjustment chamber 18. The adjustment chamber 18 is fixedly connected to the connector housing 9. A trigger chamber housing 20 is provided on the adjustment chamber 18. A partition diaphragm 21 is provided in a trigger chamber 24 of the trigger chamber housing 20. The edge of the partition diaphragm 21 is connected to the inner wall of the trigger chamber housing 20, and the partition diaphragm 21 divides the trigger chamber 24. The partition diaphragm 21 can undergo elastic deformation;

[0053] One end of an adjustment shaft body 22 is fixedly connected to the center of the partition diaphragm 21. The adjustment shaft body 22 is located in the adjustment chamber 18;

[0054] A second inlet 23 is provided on the side wall of the adjustment chamber 18. The adjustment shaft body 22 can block the passage from the second inlet 23 to the inside of the connector housing 9;

[0055] A first communication pipe 17 is connected between the connector housing 9 and the trigger chamber housing 20. A second communication pipe 19 is connected between the adjustment chamber 18 and the trigger chamber housing 20. The connection ports of the first communication pipe 17 and the second communication pipe 19 on the trigger chamber housing 20 are located on both sides of the partition diaphragm 21.

[0056] A first inlet 10 and an outlet 11 are respectively provided at both ends of the connector housing 9. The first inlet 10 is connected to the main return cooling pipe 4 through the auxiliary inlet cooling pipe 5. The outlet 11 is connected to the cooling wheel 1 through the auxiliary inlet cooling pipe 5. The second inlet 23 is connected to the next group of cooling wheels 1 through the auxiliary return cooling pipe 6.

[0057] A fixing frame 12 is fixedly connected inside the connector housing 9. One end of a linkage rod 14 is fixedly connected to the fixing frame 12. The other end of the linkage rod 14 is fixedly connected to a limit lock 16. A closing piece 13 is sleeved on the linkage rod 14. A first spring 15 is provided between the closing piece 13 and the limit lock 16. The first spring 15 is sleeved on the linkage rod 14. Both ends of the first spring 15 abut against the closing piece 13 and the limit lock 16;

[0058] The side of the closing piece 13 can be attached to the inner wall of the connector housing 9, and the inner diameter of the connector housing 9 gradually increases outward along the axis direction.

[0059] Working principle and beneficial effects of the above solution:

[0060] The coolant in the latter set of cooling wheels 1 enters the coolant in the current cooling wheel 1 through the auxiliary return water cooling pipe 6 and the main inlet cooling pipe 3 and blends in the connector 8. The temperatures of the two coolants are different and need to be combined into one temperature to enter the current cooling wheel 1 to control the temperature of the current cooling wheel 1, and this temperature cannot change sharply. At this time, the amounts of the two coolants need to be controlled. When the amount of the coolant entering through the first inlet 10 becomes smaller and the amount of the coolant entering through the second inlet 23 remains unchanged, the pressure of the coolant at the first inlet 10 is less than the pressure of the coolant at the connection between the connector housing 9 and the adjustment cavity 18, that is, the pressure on the right side of the partition diaphragm 21 is less than the pressure on the left side of the partition diaphragm 21. The partition diaphragm 21 moves to the right, driving the second communication pipe 19 to move to the right, reducing the interval between the adjustment shaft body 22 and the inner wall of the adjustment cavity 18, that is, reducing the flow passage. At this time, the coolant flowing into the connector housing 9 through the second inlet 23 decreases, and the two coolants still maintain a similar ratio, that is, they can maintain a similar temperature, ensuring that the temperature of the coolant entering the current cooling wheel 1 does not change violently, which helps to ensure the quality of the material 40;

[0061] When the amount of the coolant entering through the first inlet 10 increases and the amount of the coolant entering through the second inlet 23 remains unchanged, the diaphragm 21 drives the second communication pipe 19 to move to the left, increasing the interval between the adjustment shaft body 22 and the inner wall of the adjustment cavity 18, that is, increasing the flow passage, and then increasing the amount of the coolant flowing into the connector housing 9.

[0062] Embodiment 3

[0063] Please refer to Figures 5 - 9 On the basis of Embodiments 1-2, a stabilizing component is provided on the outer periphery of the cooling wheel 1.

[0064] A second spring 28 is fixedly connected below the regulating plate 27, and the lower end of the second spring 28 is fixedly connected to the fixing plate 25.

[0065] A collecting pipeline 32 is arranged on the fixed plate 25. One end of the collecting pipeline 32 is fixedly connected with a funnel-shaped collector. A scraping plate 31 is fixedly connected to the collector. The scraping plate 31 is located on one side of the cooling wheel 1. The lower end of the collecting pipeline 32 penetrates through the fixed plate 25 and is connected to a collecting box.

[0066] The scraping plate 31 is made of a flexible material.

[0067] A main stabilizing frame 33 is rotatably connected to the fixed plate 25. The upper end of the main stabilizing frame 33 is rotatably connected to the middle section of a sub-stabilizing frame 34 through a first stabilizing rotating shaft 36. One end of the sub-stabilizing frame 34 is rotatably connected to a stabilizing wheel 35. The stabilizing wheel 35 can be attached to the cooling wheel 1. The other end of the sub-stabilizing frame 34 is connected to one end of a third spring 37. The other end of the third spring 37 is fixedly connected to a baffle 38. The baffle 38 is fixedly connected to the main stabilizing frame 33.

[0068] A locking assembly 39 is arranged between the main stabilizing frame 33 and the fixed plate 25. The locking assembly 39 includes a second stabilizing rotating shaft 43. The second stabilizing rotating shaft 43 is fixedly connected to the fixed plate 25. A locking shaft 41 is rotatably inserted into the fixed plate 25.

[0069] The main stabilizing frame 33 is rotatably connected to the second stabilizing rotating shaft 43. A locking gear ring 42 is fixedly connected to the main stabilizing frame 33. The locking gear ring 42 is located outside the second stabilizing rotating shaft 43.

[0070] A rotating groove is arranged on the end face of the locking shaft 41, and a clamping groove is arranged on the edge side of the end face of the locking shaft 41.

[0071] A locking rod 44 is slidably connected to the end face of the second stabilizing rotating shaft 43. The locking rod 44 can be clamped in the clamping groove and the locking gear ring 42.

[0072] The working principle and beneficial effects of the above solution:

[0073] To ensure effective cooling of the material 40, it is necessary to make the material 40 closely attached to the cooling wheel 1 to maintain the largest contact area and ensure the cooling efficiency.

[0074] The cooling wheel 1 is rotatably connected to the mounting frame 29 through the main rotating shaft 30, effectively avoiding relative displacement between the cooling wheel 1 and the material 40 and avoiding deformation of the material 40 caused by friction.

[0075] The mounting frame 29 can compress the second spring 28 to move in the up and down directions, making the material 40 always in a tensioned state, which can ensure that the cooling wheel 1 is closely attached to the material 40 and ensure the cooling efficiency.

[0076] The scraper 31 provided on one side of the cooling wheel 1 is in contact with the cooling wheel 1, and can scrape off the impurities on the surface of the cooling wheel 1, so that they enter the collection box through the collection pipeline 32, ensuring the cleanliness of the surface of the cooling wheel 1;

[0077] By adjusting the opening and closing angle of the main stabilizer 33, the secondary stabilizer 34 connected to the main stabilizer 33 acts on the cooling wheel 1 with different pressures (the compression amounts of the third springs 37 are different), that is, the stabilizer wheels 35 on the secondary stabilizer 34 press on the cooling wheel 1 with different pressures, so that the material 40 located between the stabilizer wheel 35 and the cooling wheel 1 is in different pressure states, ensuring that the material 40 can be in close contact with the cooling wheel 1, and different pressures are set according to the friction factor between the material 40 and the cooling wheel 1, so that the frictional force between the material 40 and the cooling wheel 1 can make the cooling wheel 1 drive the material 40 to move forward;

[0078] By rotating the locking shaft 41, the clamping groove on the locking shaft 41 is misaligned with the locking head 45, and the locking rod 44 is clamped in the locking tooth ring 42 to complete the determination of the angle of the main stabilizer 33. When the locking head 45 is inserted into the clamping groove on the locking shaft 41, the locking rod 44 will disengage from the locking tooth ring 42. At this time, the main stabilizer 33 can rotate freely for angle adjustment.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
