Description

Technical Field

[0001] This utility model belongs to the technical field of straw production equipment, and in particular relates to a cooling device for a straw production line. Background Technology

[0002] During the production process, plastic straws are discharged from the molding machine's outlet, undergo initial water bath cooling and shaping, and are then cut to predetermined lengths before being transferred to the packaging process. Before being fed into the packaging equipment, the straws typically require further cooling to lower their temperature. Since the straws are already stacked after cutting and are transferred to subsequent stages via trays, further cooling becomes difficult. A suitable cooling device for a straw production line should rapidly cool the straws without affecting their normal flow. Current cooling devices struggle to meet these requirements, necessitating structural design and development. Utility Model Content

[0016] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0017] Please see Figure 1 and Figure 2 The cooling device for the straw production line of this utility model includes two fixed side panels 1 arranged opposite to each other, a movable side panel 13 is provided on the inner side of the fixed side panel 1 located on the right, and a spacing adjustment component 12 for driving the movable side panel 13 to move is installed between the two fixed side panels 1.

[0018] In this embodiment, the spacing adjustment assembly 12 includes two lead screws 12-3, one at the front and one at the back. The lead screws 12-3 are installed between the bottoms of the two fixed side panels 1. An adjusting rod 12-1 is provided at the outer end of one of the lead screws 12-3. Both lead screws 12-3 are provided with nuts, and the two nuts are fixedly connected to the bottom of the movable side panel 13. Synchronous sprockets 12-4 are installed at the ends of the two lead screws 12-3, and a synchronous chain is provided between the two synchronous sprockets 12-4. To improve the smoothness of movement, a guide rod 12-2 with a guide sleeve is also installed between the bottoms of the two fixed side panels 1. The guide sleeve is fixedly connected to the bottom of the movable side panel 13.

[0019] The adjusting rod 12-1 has an adjusting end that is compatible with adjusting tools such as wrenches. When it is necessary to adjust the lateral position of the movable side panel 13, the adjusting rod 12-1 is manually driven to rotate forward or in reverse using a tool. The lead screw 12-3 corresponding to the adjusting rod 12-1 rotates forward or in reverse. Under the action of the synchronous sprocket 12-4 and the synchronous chain, the other lead screw 12-3 also rotates forward or in reverse synchronously. Thus, the movable side panel 13 moves towards the fixed side panel 1 on the left or away from the fixed side panel 1 on the left, realizing the spacing adjustment. The purpose of the aforementioned spacing adjustment is to better adapt to the width of the straw tray.

[0020] Guide components for guiding the straw tray are installed on the top of both the fixed side panel 1 and the movable side panel 13 on the left side. For example... Figure 2As shown in the figure, in this embodiment, the guide assembly includes a wheel base plate 17 and a plurality of guide rollers 15 mounted on the bottom of the wheel base plate 17. When the distance between the fixed side panel 1 and the movable side panel 13 on the left is adjusted to match the width of the straw tray, the two side edges of the straw tray contact the guide rollers 15 of the two guide assemblies respectively. As shown in the figure, the wheel base plate 17 of the left guide assembly is fixedly mounted on the top of the fixed side panel 1 on the left, and the wheel base plate 17 of the right guide assembly is fixedly mounted on the top of the movable side panel 13. When the straw tray passes between the two guide assemblies, the two side edges contact the guide rollers 15 on both sides respectively, making the movement smoother.

[0021] Both the fixed side panel 1 and the movable side panel 13 on the left side are equipped with a shifting assembly 2 for driving the straw tray to move. For example... Figure 2 As shown in the figure, in this embodiment, the shifting component 2 includes a shifting motor 2-1 and a drive pulley 2-2 driven by the shifting motor 2-1, as well as a plurality of driven pulleys 2-3 and a shifting belt 2-4 wound around the drive pulley 2-2 and each driven pulley 2-3. The shifting belt 2-4 has a flat section at the top, and the left edge of the straw tray falls on the top flat section of the left shifting belt 2-4, and the right edge of the straw tray falls on the top flat section of the right shifting belt 2-4.

[0022] As shown in the figure, the shift motor 2-1 of the left shift assembly 2 is fixedly mounted on the outer side of the middle of the fixed side panel 1 on the left. The driving pulley 2-2 is located on the inner side of the middle of the fixed side panel 1. The driven pulley 2-3 includes two driven pulleys 2-3 located on both sides of the driving pulley 2-2 and two driven pulleys 2-3 installed at the front and rear ends of the fixed side panel 1. Similarly, the shift motor 2-1 of the right shift assembly 2 is fixedly mounted on the outer side of the middle of the movable side panel 13. The driving pulley 2-2 is located on the inner side of the middle of the movable side panel 13. The driven pulley 2-3 includes two driven pulleys 2-3 located on both sides of the driving pulley 2-2 and two driven pulleys 2-3 installed at the front and rear ends of the movable side panel 13. Considering that the movable side panel 13 moves laterally, a window for accommodating the shift motor 2-1 of the right shift assembly 2 is also provided in the middle of the fixed side panel 1 on the right.

[0023] In this embodiment, a left outer shell 11 is installed on the outside of the fixed side 1 on the left side, and a right outer shell 6 is installed on the outside of the fixed side 1 on the right side. The left outer shell 11 encloses the adjusting rod 12-1 and the left displacement motor 2-1 inside, and the right outer shell 6 encloses the synchronous sprocket 12-4 and the right displacement motor 2-1 inside. In order to improve the convenience of operating the adjusting rod 12-1, a window is provided at the corresponding position on the left outer shell 11. During adjustment, the tool is inserted into the shell through the window and the adjusting rod 12-1 is operated.

[0024] An upper shell 14 is provided above the two fixed side panels 1. A top cover 4 with air vents is hinged to the upper shell 14 by a hinge 5. An upper fan 3 is installed on the top wall of the top cover 4. The top cover 4 and the upper fan 3 can rotate and open around the hinge 5. When the top cover 4 is flipped open, the top of the upper shell 14 is open, which facilitates operation inside.

[0025] It also includes a lifting drive assembly that can drive the straw tray to move up and down, and a lower fan 9 is installed on the lifting drive assembly. In this embodiment, the lifting drive assembly includes a tray 7 with perforations 16, a base frame 8 installed below the middle of the tray 7, and a lifting cylinder 10 disposed below the base frame 8. The upper end of the piston rod of the cylinder 10 is fixedly connected to the base frame 8. The lifting cylinder 10 is fixedly mounted on the frame of the production line, and the lower fan 9 is fixedly mounted on the bottom of the tray 7.

[0026] When the piston rod of the lifting cylinder 10 extends upward, the support plate 7 and its lower fan 9 rise, lifting the upper suction tray a certain height to bring it closer to the upper fan 3. At this time, the suction tray separates from the two shifting components 2. When the piston rod of the lifting cylinder 10 retracts downward, the support plate 7 and its lower fan 9 descend, and the suction tray descends a certain height and falls again onto the top straight section of the shifting belts 2-4 of the two shifting components 2.

[0027] Operating method:

[0028] The straw tray containing straws is conveyed to the cooling device by the front conveyor. The shifting component 2 of the cooling device operates synchronously, pausing when the straw tray is moved to the middle position of the device. Then, the lifting cylinder 10 lifts the tray 7 and its lower fan 9, so that the straw tray is lifted to a certain height to be closer to the upper fan 3. The upper fan 3 and the lower fan 9 generate a cooling airflow from top to bottom (the airflow enters through the air hole of the top cover 4, passes down through the hole on the straw tray and the perforation 16 on the tray 7), which cools the straws in the tray. After cooling for a set time (e.g., 30s), the lifting cylinder 10 lowers the tray 7 to its original position. At this time, the straw tray falls back onto the top straight section of the shifting belt 2-4 of the two shifting components 2. The two shifting components 2 operate synchronously to transfer the straw tray to the rear conveyor.
