Description

Technical Field

[0001] This invention relates to the field of cooling equipment technology, and more specifically, to a rapid cooling device for the production of rubber and plastic products. Background Technology

[0002] With the progress of industrialization, rubber and plastic products are playing an increasingly important role. During the production and processing of rubber and plastic products, cooling is required. Traditionally, cooling devices are needed to cool and shape the rubber and plastic products.

[0003] After searching existing published literature, patent publication number CN107775855A discloses a device for improving the cooling efficiency of rubber products. This device addresses the issue that rubber and plastic products require high-temperature molding during production and subsequent cooling. Traditional cooling equipment is complex, and some use water cooling, resulting in significant water waste and often failing to achieve the desired cooling effect, severely impacting work efficiency. Therefore, we have made an improvement. This patent improves the cooling efficiency of rubber and plastic products by first using water spray cooling followed by fan cooling, and also recycles the cooling water, saving water resources. However, this cooling device has the following drawbacks.

[0004] While this cooling device can cool rubber and plastic products by passing them through water mist and airflow, the large contact area between the lower surface of the rubber and plastic products and the upper surface of the entire conveyor belt makes it difficult for the airflow and water mist to quickly cool the lower surface of the rubber and plastic products. Furthermore, after the cooling water comes into contact with the rubber and plastic products, it is necessary to wipe or dry them to remove water stains. As a result, the cooling process efficiency of rubber and plastic products is low. Therefore, a rapid cooling device for the production of rubber and plastic products is needed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rapid cooling device for the production of rubber and plastic products.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid cooling device for the production of rubber and plastic products, comprising two symmetrically arranged collar supports, wherein the top of each collar support is provided with a first collar block and a second collar block arranged sequentially from front to back, the first collar block is provided with a linkage switching mechanism inside, and an interval cooling component is provided between the two collar supports.

[0007] The linkage shifting mechanism includes a horizontally sliding linkage push rod located inside the first ring block, with a push cylinder welded to one end of the linkage push rod and a push mesh plate welded to the other end. A concave linkage frame is provided above the outer wall of the linkage push rod. A linkage slide rod is horizontally slidingly connected inside the second ring block, with a push frame plate parallel to the push mesh plate welded to one end of the linkage slide rod. A multi-directional cooling mechanism is provided above the two ring supports. The top ends of the two ring supports are respectively fixedly connected to the first and second ring blocks one-to-one. The top ends of the outer walls of the linkage push rod and the linkage slide rod are both welded and fixed to the concave linkage frame. The second ring block, the first ring block, and the concave linkage frame are all made of stainless steel.

[0008] Preferably, the bottom end of the push cylinder is equipped with a linkage rod with an L-shaped vertical cross section, and one end of the linkage rod is welded to one side of the collar bracket. The bottom end of the collar bracket is fixedly connected to a support base by bolts, and a control button is glued to one end of one of the collar brackets by hot melt adhesive.

[0009] Preferably, the interval cooling assembly includes multiple transmission belts disposed between two collar brackets, and the transmission belts have a linkage shaft and a drive shaft arranged sequentially from left to right inside. A drive pulley is coaxially welded to one end of both the drive shaft and the linkage shaft, and a drive belt is driven to the outside of the drive pulley. A servo geared motor is coaxially driven to one end of one of the drive pulleys. A reinforcing support rod is bonded and fixed between adjacent transmission belts. The multiple transmission belts are arranged equidistantly from front to back. The linkage shaft and the drive shaft are driven to the transmission belts. A support base plate is welded to the lower outer wall of the servo geared motor, and the support base plate is made of stainless steel.

[0010] Preferably, the multi-directional cooling mechanism includes a first cooling frame positioned above the space between the two collar supports, and a second cooling frame positioned below the space between the two collar supports. A drive shaft is fixed through one side of both the first and second cooling frames. A serpentine cooling pipe is welded inside the first and second cooling frames. An inlet pipe for inputting cooling water is welded to the bottom of the serpentine cooling pipe, and an outlet pipe for outputting cooling water is welded to the top of the serpentine cooling pipe. A reinforcing ring frame is welded above both the first and second cooling frames. A fan and a fan blade are arranged sequentially from left to right inside each reinforcing ring frame. A reciprocating geared motor for rotating the first cooling frame is coaxially connected to one end of the drive shaft. One end of the fan blade is welded and fixed to the output end of the fan. A collar shaft block is rotatably connected to the outer wall of the drive shaft near both ends via bearings.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. This invention employs a linkage shifting mechanism to activate the push cylinder. The push cylinder drives the linkage push rod to move, which in turn drives the push mesh plate to move. Simultaneously, the linkage push rod drives the concave linkage frame to move, which in turn drives the linkage slide rod to move backward. This allows multiple rubber and plastic products to be pushed backward. Activating the push cylinder drives the linkage push rod to move forward, thus enabling multiple rubber and plastic products to move back and forth on the upper surface of the transmission belt. The contact points between the lower surface of the rubber and plastic products and the transmission belt continuously shift positions. The entire lower surface of the rubber and plastic products is exposed in the gap between the two transmission belts for shifting and cooling operations. This results in a wider exposed area at the bottom of the rubber products and higher heat dissipation efficiency.

[0013] 2. The present invention uses an interval cooling component to make the servo geared motor drive the drive pulley to rotate, the drive pulley drives the drive belt in linkage, the drive shaft and the linkage shaft both rotate inside the collar bracket, and the transmission belt drives the reinforcing support rod to drive. There is a large gap between two adjacent transmission belts, so the contact area between the upper surface of the transmission belt and the rubber product is greatly reduced, resulting in a larger cooling space and a wider cooling area.

[0014] 3. This invention employs a multi-directional cooling mechanism that allows cooling water to enter the serpentine cooling pipe through the inlet pipe under the action of an external pump, and then flow upwards through the serpentine cooling pipe to the outlet pipe. The serpentine cooling pipe can exchange heat with the air and lower its temperature. The reciprocating reduction motor is started to drive the transmission shaft to rotate downwards by 30 degrees and then upwards by 30 degrees. The cooling air can reciprocate and cool the rubber and plastic products on the upper surface of the transmission belt at an angle. The rubber and plastic products can be cooled in multiple directions without dead angles, resulting in faster cooling speed. Furthermore, the cooling is water-free, which does not easily cause the rubber and plastic products to become damp. There is no need for subsequent drying and wiping, saving time.

[0015] In summary, through the interaction of the above-mentioned multiple effects, multiple rubber and plastic products first move back and forth on the upper surface of the transmission belt, and the contact points between the lower surface of the rubber and plastic products and the transmission belt continuously change position. Then, the transmission belt drives the reinforcing support rod to drive, and there is a large gap between two adjacent transmission belts. Finally, the reciprocating reduction motor is started to drive the transmission shaft to rotate downward by 30 degrees and then upward by 30 degrees. The cooling air can cool the rubber and plastic products on the upper surface of the transmission belt at a reciprocating angle. In summary, this can effectively improve the cooling efficiency of the rubber and plastic products. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] As attached Figure 1-8The diagram shows a rapid cooling device for producing rubber and plastic products. This device includes a linkage switching mechanism, an intermittent cooling component, and a multi-directional cooling mechanism. The arrangement of these mechanisms and components effectively improves the cooling efficiency of the rubber and plastic products. The specific structural configuration of each mechanism and component is as follows:

[0027] In some embodiments, as shown in the appendix Figure 1-8 As shown, the linkage shifting mechanism includes a linkage push rod 4 that is horizontally slidably connected inside the first ring block 2, and a push cylinder 5 is welded to one end of the linkage push rod 4. A push mesh plate 6 is welded to the other end of the linkage push rod 4. A concave linkage frame 7 is provided on the upper part of the outer wall of the linkage push rod 4. A linkage slide rod 8 is horizontally slidably connected inside the second ring block 3, and a push frame plate 9 parallel to the push mesh plate 6 is welded to one end of the linkage slide rod 8. A multi-directional cooling mechanism is provided above the position between the two ring brackets 1. The top ends of the two ring brackets 1 are respectively fixedly connected to the first ring block 2 and the second ring block 3. The top ends of the outer walls of the linkage push rod 4 and the linkage slide rod 8 are both welded and fixed to the concave linkage frame 7. The second ring block 3, the first ring block 2, and the concave linkage frame 7 are all made of stainless steel.

[0028] In some embodiments, as shown in the appendix Figure 1-2 As shown, a linkage rod 10 with an L-shaped vertical cross-section is installed at the bottom of the push cylinder 5, and one end of the linkage rod 10 is welded to one side of the collar bracket 1 so that the collar bracket 1 can support the linkage rod 10. The linkage rod 10 provides vertical support for the push cylinder 5, thus improving the stability of the push cylinder 5 during use. The bottom of the collar bracket 1 is fixedly connected to a support base 11 by bolts. A control button 12 is glued to one end of one of the collar brackets 1 by hot melt adhesive so that the control button 12 can be activated. The control button 12 can then support the entire cooling device.

[0029] In some embodiments, as shown in the appendix Figure 1-5 As shown, the intermittent cooling assembly includes multiple transmission belts 13 disposed between two collar brackets 1. Inside each transmission belt 13, from left to right, are sequentially arranged a linkage shaft 14 and a drive shaft 15. Drive pulleys 17 are coaxially welded to one end of both the drive shaft 15 and the linkage shaft 14. A drive belt 18 is externally connected to the drive pulley 17. A servo geared motor 19 is coaxially connected to one end of one of the drive pulleys 17. Reinforcing support rods 16 are bonded and fixed between adjacent transmission belts 13. The multiple transmission belts 13 are arranged equidistantly from front to back. Both the linkage shaft 14 and the drive shaft 15 are connected to the transmission belts 13. A support base plate 20, made of stainless steel, is welded to the lower outer wall of the servo geared motor 19.

[0030] In some embodiments, as shown in the appendix Figure 6-8 As shown, the multi-directional cooling mechanism includes a first cooling frame 21 positioned above the space between two collar supports 1, and a second cooling frame 22 positioned below the space between the two collar supports 1. A drive shaft 23 is fixed through one side of both the first cooling frame 21 and the second cooling frame 22. A serpentine cooling pipe 24 is welded inside both the first cooling frame 21 and the second cooling frame 22. An inlet pipe 25 for inputting cooling water is welded to the bottom end of the serpentine cooling pipe 24, and the top end of the serpentine cooling pipe 24 is welded to... There is an outlet pipe 26 for outputting cooling water. A reinforcing ring frame 27 is welded above the first cooling frame 21 and the second cooling frame 22. Inside each reinforcing ring frame 27, a fan 29 and a fan blade 28 are arranged from left to right. A reciprocating geared motor 31 for rotating the first cooling frame 21 is coaxially connected to one end of the drive shaft 23. One end of the fan blade 28 is welded and fixed to the output end of the fan 29. A collar shaft block 30 is rotatably connected to the outer wall of the drive shaft 23 and near its two ends through bearings.

[0031] The working principle of this invention is as follows:

[0032] During intermittent cooling, multiple injection-molded rubber and plastic products are placed on the upper surface of the transmission belt 13. The servo reduction motor 19 is vertically supported by the support base plate 20. The control button 12 is activated, which causes the servo reduction motor 19 to drive the drive pulley 17 to rotate. The drive pulley 17 drives the drive belt 18 in conjunction. At the same time, both drive pulleys 17 rotate, which in turn drives the drive shaft 15 and the linkage shaft 14. Thus, the drive shaft 15 and the linkage shaft 14 rotate inside the collar bracket 1. The transmission belt 13 drives the reinforcing support rod 16. Multiple transmission belts 13 can drive the rubber and plastic products. There is a large gap between adjacent transmission belts 13, which greatly reduces the contact area between the upper surface of the transmission belt 13 and the rubber products, and there is a large gap between them.

[0033] During the repositioning and cooling process, the push cylinder 5 is activated, which moves the linkage push rod 4. The linkage push rod 4 moves along the inside of the first set of ring blocks 2, and simultaneously moves the push mesh plate 6. The push mesh plate 6 moves multiple rubber and plastic products backward along the upper surface of the transmission belt 13. In this way, the linkage push rod 4 also moves the concave linkage frame 7, which in turn moves the linkage slide rod 8 backward. The linkage slide rod 8 moves backward along the inside of the second set of ring blocks 3, and simultaneously moves the push frame plate 9 backward, thus pushing multiple rubber and plastic products backward. The drive belt 13 can be moved backward to change position, and then the push cylinder 5 is started to drive the linkage push rod 4 to move forward. The linkage push rod 4 drives the push mesh plate 6 to move forward. At the same time, the linkage push rod 4 drives the concave linkage frame 7 to move. The concave linkage frame 7 drives the linkage slide rod 8 to move the push frame plate 9 forward. In this way, the push frame plate 9 pushes multiple rubber and plastic products forward, so that multiple rubber and plastic products can move forward on the upper surface of the drive belt 13. By continuously starting the push cylinder 5 to drive the linkage push rod 4 to move back and forth, multiple rubber and plastic products can be moved back and forth on the upper surface of the drive belt 13 to change position.

[0034] During multi-angle cooling, the factory cooling water pipes are connected to the positions between the two inlet pipes 25, and the return water pipes of the factory cooling tower are connected to the two outlet pipes 26. The cooling water enters the serpentine cooling tube 24 through the inlet pipe 25 under the action of the external pump, and flows up the serpentine cooling tube 24 to the outlet pipe 26. Then, the fan 29 inside the reinforcing ring frame 27 is started, and the fan 29 drives the fan blades 28 to rotate. In this way, the serpentine cooling tube 24 can play a role in heat exchange and cooling of the air. Then, the reciprocating reduction motor 31 is started to drive the transmission shaft 23 to rotate downward by 30 degrees and then upward by 30 degrees. At the same time, the transmission shaft 23 reciprocates inside the collar block 30, and the transmission shaft 23 drives the first cooling frame 21 to move the serpentine cooling tube 24 back and forth. In this way, the cooling air can play a reciprocating angle cooling role on the rubber and plastic products on the upper surface of the transmission belt 13.
