Description

A cooling device for processing degradable straws Technical Field

[0001] The present invention relates to the technical field of degradable straw processing, in particular to a cooling device for degradable straw processing. Background Art

[0002] Straws are used as tools for drinking liquid beverages in daily life and are mostly made of plastic. With the increasing awareness of energy conservation and environmental protection, degradable straws have been favored by people, reducing the harm to the environment and making people's lives more convenient. In the extrusion production process of existing straws, in order to prevent deformation, the plastic straws need to be cooled. The existing cooling methods mostly use water cooling for cooling. Due to the buoyancy of straws, part of the straws float on the water surface and cannot fully contact the water, affecting the cooling effect. Therefore, a cooling device for degradable straw processing is designed here to solve the above problem. Technical issues

[0003] Most existing cooling methods use water cooling for cooling. Since straws have buoyancy, part of the straws float on the water surface and cannot fully contact the water, affecting the cooling effect. Therefore, a cooling device for degradable straw processing is designed here to solve the above problem. Technical Solutions

[0004] A cooling device for processing degradable straws comprises a conveying member, a material receiving member and a water tank, wherein the conveying member comprises a portal frame, which is tilted downward to the right side, and L-shaped brackets are vertically fixed on the front and rear sides of the left side of the bottom end of the portal frame, and the two L-shaped brackets are fixedly connected to the left side wall of the water tank, and a plurality of rollers evenly spaced and rotatable on the left side wall inside the portal frame are provided, and the rollers extend to the left side of the upper end of the water tank, and the gap between two adjacent rollers is used as a channel for supporting and sliding down the degradable straws. Since the portal frame is tilted downward to the right side, the degradable straws in the channel can slide down along the tilted rollers, and there is no need to set up an additional power part to push the degradable straws down.

[0005] The connecting part includes a transmission shaft and several connecting rods. The axial ends of the transmission shaft are rotatably connected with the front and rear side walls inside the water tank. A motor is fixed to the rear side wall of the water tank. The output end of the motor rotates through the water tank and is fixedly connected to one end of the transmission shaft. Several connecting rods are distributed in parallel and fixed on the radial side walls of the transmission shaft. Rotating the transmission shaft between the front and rear side walls inside the water tank can drive the connecting rods to perform a flipping operation with the transmission shaft as the rotation center.

[0006] The motor drives the transmission shaft to rotate, and stops rotating immediately after the end of the connecting rod rotates to the end of the roller shaft, limiting the direction of the end of the connecting rod. The end of the connecting rod and the gap between the two adjacent roller shafts are located in the same vertical plane. The degradable straw that slides down from the gap between the two adjacent roller shafts can be sleeved on the outer wall of the connecting rod at the corresponding position, and the large diameter of the connecting rod must be smaller than the inner diameter of the degradable straw to facilitate loading and unloading. The length of the connecting rod must meet the requirements of multiple degradable straws. Then the motor drives the transmission shaft to flip, and the degradable straw can be flipped with the transmission shaft as the center. Cooling water is filled in the water tank, and the degradable straw that flips downward can be immersed below the liquid level of the coolant to ensure that the cooling operation is carried out effectively.

[0007] In a further embodiment, the end of the connecting rod is a spherical structure, and the end of the connecting rod and the gap between two adjacent roller shafts are located in the same vertical plane.

[0008] In a further embodiment, the plurality of connecting rods are equally divided into a plurality of groups and are evenly spaced apart along the radial outer wall of the transmission shaft.

[0009] In a further embodiment, the other end of the transmission shaft rotates through the front side wall of the water tank and then rotates to be connected to an external joint, the end of the external joint is connected to an external conduit, and the end of the transmission shaft close to the external joint is provided with an axially distributed cavity connected to the external joint, the plug-in rod is axially provided with a guide groove connected to the cavity, and the radial side wall of the plug-in rod is provided with a plurality of outlets connected to the guide groove.

[0010] In a further embodiment, the end of the external conduit is connected to the water outlet pipe of the water source, and the external water is injected into the cavity of the transmission shaft through the external joint for storage, then enters the guide groove of each plug-in rod, and then comes out through the outlet of each plug-in rod to flush and cool the inner wall of the degradable straw, thereby realizing dual cooling operation inside and outside.

[0011] In a further embodiment, the end of the external conduit is connected to the air outlet of the air cooler, and the cold air blown by the air cooler is blown into the cavity of the drive shaft, then enters the guide groove of each plug-in rod, and then blown out through the outlet of each plug-in rod to cool the inner wall of the degradable straw.

[0012] In a further embodiment, arc-shaped limit baffles are provided on both the front and rear sides of the upper end face of the portal frame.

[0013] In a further embodiment, a support rod is fixed to the left end of the L-shaped bracket at an angle, and a storage box is fixed to the upper end of the two support rods. The right end of the storage box extends to the left side of the upper end of the portal frame, and a discharge port is provided at the bottom end of the right end surface of the storage box. The storage box is tilted at the left side of the upper end of the portal frame for storing degradable straws in batches. The degradable straws are affected by the inclination and slide out of the discharge port and fall onto the roller.

[0014] In a further embodiment, a plurality of baffles are fixed between the upper and lower side walls inside the discharge port. Beneficial effects

[0015] The present invention is a cooling device for processing degradable straws. It utilizes a receiving piece to batch-collect degradable straws that slide down from the gap between two adjacent rollers. The receiving piece is then rotated to sink the degradable straws below the liquid level in a water tank, ensuring effective cooling. This solves the problem of straws having buoyancy, causing some of the straws to float on the water surface and not fully contacting the water, thus affecting the cooling effect.

[0022] Please refer to Figures 1-5. This embodiment provides a cooling device for processing degradable straws, including a conveying part, a material receiving part and a water tank 3. The conveying part includes a portal frame 1, which is tilted to the lower right side. L-shaped brackets 12 are vertically fixed on the front and rear sides of the left side of the bottom end of the portal frame 1. The two L-shaped brackets 12 are fixedly connected to the left side wall of the water tank 3. The portal frame 1 is suspended and erected at the upper left side of the water tank 3 using the two L-shaped brackets 12. A number of rollers 11 are evenly spaced and rotated on the left side wall inside the portal frame 1. The rollers 11 extend to the left side of the upper end of the water tank 3. A large number of high-temperature formed degradable straws are placed on the support composed of the several rollers 11, and the gap between two adjacent rollers 11 is used as a channel for supporting and sliding the degradable straws. Since the portal frame 1 is tilted to the lower right side, the degradable straws in the channel can slide down along the tilted rollers 11, and there is no need to set up additional power parts to push the degradable straws down.

[0023] It should be noted that the width of the gap between two adjacent rollers 11 cannot be smaller than the major diameter of the degradable straw to prevent the degradable straw from falling from the gap and being unable to slide down for transportation.

[0024] The end of the plug rod 32 is a spherical structure, which facilitates the quick alignment and insertion of the degradable straw into the outer wall of the plug rod 32 .

[0025] The connecting parts include a transmission shaft 31 and several connecting rods 32. The axial ends of the transmission shaft 31 are rotatably connected to the front and rear side walls inside the water tank 3. Several connecting rods 32 are distributed in parallel and fixed on the radial side walls of the transmission shaft 31. Rotating the transmission shaft 31 between the front and rear side walls inside the water tank 3 can drive the connecting rods 32 to perform a flipping operation with the transmission shaft 31 as the rotation center.

[0026] The motor 36 is fixed to the side wall of the rear side of the water tank 3. The output end of the motor 36 rotates through the water tank 3 and is fixedly connected to one end of the transmission shaft 31. The motor 36 is a servo motor, which is used to drive the transmission shaft 31 to rotate. When the end of the connecting rod 32 rotates to the end of the roller 11, it stops rotating immediately, limiting the direction of the end of the connecting rod 32. The end of the connecting rod 32 and the gap between the two adjacent rollers 11 are located in the same vertical plane. The degradable straw that slides down from the gap between the two adjacent rollers 11 can be sleeved on the outer wall of the connecting rod 32 at the corresponding position, and the large diameter of the connecting rod 32 is smaller than the inner diameter of the degradable straw, which is convenient for loading and unloading. The length of the connecting rod 32 must meet the requirements of the sleeve of multiple degradable straws. Then the motor 36 drives the transmission shaft 31 to flip, and the degradable straw can be flipped around the transmission shaft 31 as the center, filling the water tank 3 with cooling water. The degradable straw that flips downward can be immersed below the liquid level of the coolant, ensuring that the cooling operation is effective.

[0027] The receiving piece is used to batch-collect the degradable straws that slide down from the gap between two adjacent rollers 11, and then the receiving piece is rotated to sink the degradable straws below the liquid level in the water tank 3, ensuring effective cooling. This solves the problem that due to the buoyancy of the straws, some of the straws float on the water surface and cannot fully contact the water, thus affecting the cooling effect.

[0028] Several plug-in rods 32 are equally divided into several groups and are evenly spaced along the radial outer wall of the transmission shaft 31. Depending on the amount of cooling required for the degradable straws, multiple groups of plug-in rods 32 are appropriately selected. Only one group of plug-in rods 32 is shown in FIG1 , which is sufficient to meet the cooling requirements of the degradable straws.

[0029] Arc-shaped limit baffles 13 are provided on both the front and rear sides of the upper end face of the portal frame 1. By providing the limit baffles 13, the degradable straws can be prevented from falling off the roller shaft 11.

[0030] The left end of the L-shaped bracket 12 is tilted toward the left and a support rod 22 is fixed thereto. A storage box 2 is fixed to the upper ends of the two support rods 22. The right end of the storage box 2 extends to the left side of the upper end of the portal frame 1, and a discharge port is provided at the bottom end of the right end face of the storage box 2. The storage box 2 is tilted at the left side of the upper end of the portal frame 1 and is used for storing degradable straws in batches. The degradable straws are affected by the inclination and slide out of the discharge port and fall onto the roller 11.

[0031] Several baffles 21 are fixed between the upper and lower side walls inside the discharge port. By setting up multiple baffles 21 and the gap between two adjacent baffles 21 being smaller than the length of the degradable straw, the degradable straw is prevented from falling horizontally onto the roller 11, affecting the insertion of the degradable straw into the insertion rod 32. Modes for Carrying Out the Invention

[0032] Please refer to Figures 1-5, which show further improvements based on Example 1:

[0033] The other end of the transmission shaft 31 rotates through the front side wall of the water tank 3 and then rotates to connect to the external joint 33. The end of the external joint 33 is connected to an external conduit. An axially distributed cavity 34 is opened at one end of the transmission shaft 31 close to the external joint 33 and connected to the external joint 33. A guide groove connected to the cavity 34 is opened axially on the plug-in rod 32, and a plurality of outlets 35 connected to the guide groove are opened on the radial side wall of the plug-in rod 32. The end of the external conduit is connected to the water outlet pipe. The external water is injected into the cavity 34 of the transmission shaft 31 through the external joint 33 for storage, and then enters the guide groove of each plug-in rod 32, and then comes out through the outlet 35 of each plug-in rod 32 to flush and cool the inner wall of the degradable straw, realizing internal and external dual cooling operation.

[0034] In addition to the dual water cooling method inside and outside, the end of the external conduit is connected to the air outlet of the air cooler, and the cold air blown by the air cooler is blown into the cavity 34 of the drive shaft 31, then enters the guide groove of each plug-in rod 32, and then blown out through the outlet 35 of each plug-in rod 32 to cool the inner wall of the degradable straw.

[0035] Any of the above cooling methods can be selected.
