Description
Technical Field
[0001] This application relates to the technical field of foamed particle conveying equipment, and specifically to a conveying device for foamed particles. Background Technology
[0002] In the production and processing of foamed granules, the conveying process is crucial. However, traditional foamed granule conveying devices have several problems. Due to the special texture of foamed granules, they are prone to mutual compression and adsorption, often forming accumulations during conveying and hindering smooth downward transport, leading to frequent interruptions in the conveying process. Moreover, the conveying efficiency of traditional devices is generally low, making it difficult to meet the needs of large-scale production. In addition, the structural design of the device may be inadequate, failing to effectively adapt to the characteristics of foamed granules, resulting in granule blockage or scattering during conveying and causing material waste.
[0003] Therefore, a conveying device is needed that can solve the problem of foamed particle accumulation, improve conveying efficiency, and adapt to particle characteristics to ensure the smooth operation of the foamed particle production and processing process. Summary of the Invention
[0004] To address the aforementioned technical problems, this application solves the problem that foamed particles are prone to accumulating due to mutual compression and adsorption during the conveying process, resulting in difficulties in smooth downward conveying and low conveying efficiency.

A lower fan and an upper fan are rotatably mounted on the end of the lower main shaft away from the upper main shaft, and the lower fan and the upper fan are fixedly connected by a pipe. An upper support and a lower support are fixedly mounted on the vertical rod. An upper pipe is fixedly mounted on the upper support and is fixedly connected to the outlet of the storage bag. A lower pipe is fixedly mounted on the lower support.
[0006] To better realize this application, a motor is fixedly installed on the lower bracket, a side shaft is rotatably provided on the upper bracket, the side shaft is fixedly connected to the output end of the motor, a side shaft is fixedly installed at one end of the side shaft near the upper bracket, an upper gear ring is rotatably provided on the upper pipe, the upper gear ring meshes with the upper gear, an inner mounting ring is fixedly provided on the upper gear ring, and the inner mounting ring is fixedly connected to the lower main shaft.
[0007] To better realize this application, a lower gear ring is rotatably provided on the lower pipe, the lower gear ring is fixedly connected to the lower fan, and a lower gear is fixedly installed on one end of the side shaft near the lower gear ring. The lower gear meshes with the lower gear ring, and the number of teeth of the lower gear is greater than that of the side shaft.
[0008] To better realize this application, the upper bracket is further provided with a mounting block, on which a middle pipe is fixedly mounted. The end of the middle pipe near the inner mounting ring is rotatably connected to the inner mounting ring, and the end of the middle pipe near the lower toothed ring is rotatably connected to the lower toothed ring.
[0009] To better realize this application, a side pipe is further fixedly provided on the intermediate pipe, and a filter screen is provided on the side pipe.
[0010] To better realize this application, the support assembly further includes an inner slide rod, an outer slide rod, a connecting ring, a middle slide rod, an outer spring, an inner spring, and a limiting block. The end of the inner slide rod near the upper main shaft is slidably disposed on the slide groove of the upper main shaft, and the end of the inner slide rod away from the upper main shaft is slidably disposed on the inner wall of the outer slide rod. The end of the outer slide rod away from the upper main shaft is slidably disposed on the slide rail. The connecting ring is slidably disposed on the outer slide rod. The end of the middle slide rod away from the upper main shaft is fixedly installed on the outer slide rod. The inner slide rod is provided with a slide groove, and the end of the middle slide rod near the upper main shaft slides on the slide groove. The outer spring and the inner spring are both sleeved on the end of the middle slide rod near the upper main shaft. The limiting block is fixedly installed on the end of the inner slide rod slide groove away from the upper main shaft.
[0011] To better realize this application, the connecting ring is further provided with two connection points, which are respectively connected to different ends of the two upper spiral plates.
[0012] To better realize this application, the upper spiral plate is further provided with two vertical slide rods at one end near the upper main shaft, and the two vertical slide rods are respectively slidably disposed on two adjacent slide grooves on the upper main shaft.
[0013] The technical solution provided in this application has the following advantages compared with the prior art:
[0014] 1. This application achieves layered agitation and directional conveying of foamed particles by setting up upper and lower spiral plates, effectively avoiding the formation of fixed accumulation of foamed particles due to mutual compression and adsorption, ensuring that they can be conveyed downward layer by layer, and improving the smoothness of conveying.
[0015] 2: This application utilizes a motor drive and gear transmission structure to drive the lower main shaft, upper main shaft, and fan to rotate. The rapid rotation of the fan generates airflow, which propels the foamed particles to move rapidly within the lower pipe, significantly improving the conveying efficiency of the foamed particles.
[0016] 3: This application sets a side pipe with a filter screen in the middle pipe, so that the external gas is filtered and smoothly combined with the foamed particles. The airflow accelerates the conveying of the foamed particles and further optimizes the conveying effect.
[0017] 4: The support component designed in this application, through the inner and outer slide rods and spring structure, can automatically adjust its length according to the change of the slide rail shape. While ensuring the support capacity of the upper spiral plate, the spring force promotes the change of the movement direction of the outer slide rod, ensuring the stable rotation of the upper spiral plate and ensuring the stability of the conveying process.
[0018] 5: This application sets mesh holes in the upper spiral plate, which realizes effective control of the conveying speed of foamed particles. This can not only avoid the particles squeezing the parts when the pressure below is too high, but also reasonably reduce the conveying capacity during normal conveying, making the conveying process more controllable.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] like Figures 1 to 7As shown, a conveying device for foamed granules includes a vertical rod 101 and a storage bag 103. Multiple ring frames 102 are fixedly mounted on the vertical rod 101, and a slide rail 104 is fixedly mounted on each ring frame 102. The storage bag 103 is disposed on the ring frame 102 and located between the ring frame 102 and the slide rail 104. The storage bag 103 is fixed by the slide rail 104 and the ring frame 102. An upper mounting rod 105 is fixedly mounted on the ring frame 102, and an upper main shaft 106 is rotatably mounted on the upper mounting rod 105. The upper main shaft 106 has four sliding grooves, two of which have multiple upper spiral plates 107 slidably mounted on them, and the other two grooves each have multiple... The support components include two symmetrically arranged support components that slide on a slide rail 104. A lower main shaft 108 is fixedly mounted on the end of the upper spiral plate 107 away from the upper mounting rod 105. A lower spiral plate 109 is fixedly mounted on the lower main shaft 108. A lower fan 116 and an upper fan 117 are rotatably mounted on the end of the lower main shaft 108 away from the upper main shaft 106. The lower fan 116 and the upper fan 117 are fixedly connected by a pipe. An upper bracket 118 and a lower bracket 123 are fixedly mounted on the vertical rod 101. An upper pipe 119 is fixedly mounted on the upper bracket 118 and is fixedly connected to the discharge port of the storage bag 103. A lower pipe 121 is fixedly mounted on the lower bracket 123.
[0030] Specifically, such as Figure 1 As shown, four vertical rods 101 are installed on the slide rail 104, and the vertical rods 101 are fixed together by rods to maintain stability. Four ring frames 102 are installed on each vertical rod 101. Figure 4 As shown, a convex shaft is provided on the outer surface of the slide rail 104, and a matching groove is provided on the inner surface of the ring frame 102. The storage pocket 103 is located between the ring frame 102 and the slide rail 104. The convex shaft of the slide rail 104 pushes the storage pocket 103 into the groove of the ring frame 102, thereby fixing the storage pocket 103 and stably installing the slide rail 104, preventing it from falling off due to insufficient friction between the slide rail 104 and the ring frame 102.
[0031] The length of the upper main shaft 106 is the same as the height of the four-layer slide rail 104. By controlling the rotation of the upper main shaft 106 on the upper mounting rod 105, the slide groove on the upper main shaft 106 drives the upper spiral plate 107 to stir the foamed particles between each layer of slide rail 104. This prevents the foamed particles from becoming fixed due to mutual compression and adsorption and not being conveyed downwards. The foamed particles are conveyed layer by layer downwards by setting the spiral angle of the upper spiral plate 107.
[0032] The lower end of the storage bag 103 has a conical structure. This part drives the lower main shaft 108 to rotate through the upper main shaft 106. The lower spiral plate 109 on the lower main shaft 108 drives the foamed particles near the axis of the lower main shaft 108 to be conveyed downward. Meanwhile, the foamed particles in other parts of the conical structure of the storage bag 103 move downward along the conical inclined surface of the storage bag 103 by the compression of the upper layer, approach and contact the lower spiral plate 109, and are finally conveyed by the lower spiral plate 109 into the upper pipe 119, pass through the middle pipe 120 and finally be conveyed out by the lower pipe 121.
[0033] like Figure 2 and Figure 7 As shown, a motor 124 is fixedly mounted on the lower bracket 123, and a side shaft 113 is rotatably mounted on the upper bracket 118. The side shaft 113 is fixedly connected to the output end of the motor 124. The side shaft 113 is fixedly mounted at one end near the upper bracket 118. An upper gear ring 111 is rotatably mounted on the upper pipe 119. The upper gear ring 111 meshes with the upper gear 112. An inner mounting ring 110 is fixedly mounted on the upper gear ring 111 and is fixedly connected to the lower main shaft 108.
[0034] Specifically, the motor 124 is started by the control unit. The output of the motor 124 drives the side shaft 113 to rotate on the upper bracket 118. The upper gear 112 on the side shaft 113 drives the inner mounting ring 110 to rotate on the upper pipe 119 through meshing with the upper gear ring 111. At the same time, the inner mounting ring 110 drives the lower main shaft 108 to rotate. The lower main shaft 108 drives the upper main shaft 106 and the lower spiral plate 109 to rotate, which in turn drives the multiple support groups and the upper spiral plate 107 set on the slide groove of the upper main shaft 106 to rotate, thereby realizing the conveying of foamed particles at the lower spiral plate 109 and the conveying of foamed particles at the upper main shaft 106. The upper end of the lower main shaft 108 is connected to the upper main shaft 106 to form a support. The lower end of the lower main shaft 108 is supported by the rotational connection between the inner mounting ring 110 and the upper pipe 119, and the rotational connection between the lower fan 116 and the intermediate pipe 120 and the lower pipe 121.
[0035] like Figure 7 As shown, a lower gear ring 115 is rotatably mounted on the lower pipe 121. The lower gear ring 115 is fixedly connected to the lower fan 116. A lower gear 114 is fixedly mounted on one end of the side shaft 113 near the lower gear ring 115. The lower gear 114 meshes with the lower gear ring 115. The number of teeth of the lower gear 114 is greater than that of the side shaft 113.
[0036] Specifically, when the side shaft 113 rotates, it also drives the lower gear 114. Through the meshing relationship between the lower gear 114 and the lower gear ring 115, the lower gear ring 115 is driven to rotate on the middle pipe 120 and the lower pipe 121, which in turn drives the lower fan 116 to rotate on the lower main shaft 108. Because the number of teeth of the lower gear 114 is greater than that of the side shaft 113, the rotation speed of the lower fan 116 is greater than that of the lower main shaft 108. The lower fan 116 drives the upper fan 117 to rotate through the pipe. Through the rapid rotation of the lower fan 116 and the upper fan 117, the airflow is moved, which drives the foaming particles delivered by the upper lower spiral plate 109 to be quickly conveyed out. The gas is used to push the foaming particles to move quickly in the lower pipe 121.
[0037] like Figure 2 As shown, an mounting block is provided on the upper bracket 118, and an intermediate pipe 120 is fixedly installed on the mounting block. The end of the intermediate pipe 120 near the inner mounting ring 110 is rotatably connected to the inner mounting ring 110, and the end of the intermediate pipe 120 near the lower toothed ring 115 is rotatably connected to the lower toothed ring 115.
[0038] Specifically, the upper end of the intermediate pipe 120 is rotatably connected to the inner mounting ring 110, and the lower end of the intermediate pipe 120 is rotatably connected to the lower toothed ring 115. The intermediate pipe 120 itself is fixedly connected to the upper bracket 118 through the mounting block, thereby supporting the stability of the intermediate pipe 120 through the upper bracket 118. Thus, when the inner mounting ring 110 and the lower toothed ring 115 rotate, the intermediate pipe 120 will not shake due to instability.
[0039] like Figure 2 As shown, a side pipe 122 is fixedly installed on the intermediate pipe 120, and a filter screen is installed on the side pipe 122.
[0040] Specifically, the side pipe 122 is installed at an angle on the middle pipe 120. External gas enters the middle pipe 120 after being filtered through a filter screen through the opening at the left end of the side pipe 122. The gas flow direction is to move to the lower right, so as to smoothly combine with the foaming particles conveyed downward above the middle pipe 120. After the foaming particles and gas are mixed, the airflow is accelerated by the drive of the lower fan 116 and the upper fan 117, and then the airflow drives the foaming particles to be conveyed quickly.
[0041] like Figures 3 to 6As shown, the support assembly includes an inner slide rod 125, an outer slide rod 126, a connecting ring 127, a middle slide rod 128, an outer spring 129, an inner spring 130, and a limiting block 131. One end of the inner slide rod 125, near the upper spindle 106, is slidably mounted on the slide groove of the upper spindle 106. The other end of the inner slide rod 125, away from the upper spindle 106, is slidably mounted on the inner wall of the outer slide rod 126. The other end of the outer slide rod 126, away from the upper spindle 106, is slidably mounted on the slide rail 104. The connecting ring 127 is slidably mounted on the outer slide rod 126. The end of the middle slide rod 128 away from the upper main shaft 106 is fixedly mounted on the outer slide rod 126. The inner slide rod 125 is provided with a slide groove. The end of the middle slide rod 128 near the upper main shaft 106 slides on the slide groove. The outer spring 129 and the inner spring 130 are both sleeved on the end of the middle slide rod 128 near the upper main shaft 106. The end of the inner slide rod 125 slide groove away from the upper main shaft 106 is fixedly mounted with a limit block 131.
[0042] Specifically, such as Figure 3 and Figure 4 As shown, each pair of support components forms a group, and each group is symmetrically arranged on two slide grooves of the upper main shaft 106. The upper and lower adjacent support components and the upper spiral plate 107 are arranged at a 90-degree angle to each other. A gap is provided between the upper spiral plate 107 and the support components. The upper spiral plate 107 is provided with mesh holes for the foamed particles to pass through. The mesh holes prevent the foamed particles in the storage bag 103 from being conveyed too quickly and squeezing the parts below. Through the mesh holes, when the pressure below is too high, the foamed particles are squeezed and accelerated to pass through the mesh holes of the upper spiral plate 107, relieving the pressure. During normal conveying, the foamed particles also pass through the mesh holes, reducing the conveying capacity.
[0043] When the support assembly rotates with the upper main shaft 106, because the slide rail 104 is approximately square in shape to maximize the utilization area and store more foamed particles, as shown in Figure 4, when the upper main shaft 106 rotates clockwise, the distance between the end of the support assembly away from the upper main shaft 106 and the upper main shaft 106 will gradually increase. That is, the upper main shaft 106 drives the outer slide rod 126 to rotate through the inner slide rod 125, and the end of the outer slide rod 126 near the slide rail 104 slides on the slide rail 104. As the distance increases, the outer slide rod 126 slides on the inner slide rod 125, and drives the inner spring 130 and the outer spring 129 to move away from the upper main shaft 106 through the middle slide rod 128. When the outer slide rod 126 moves to the corner of the slide rail 104, the distance reaches its maximum, and the movement distance of the outer slide rod 126 on the inner slide rod 125 also reaches its maximum. As it continues to move, the distance gradually decreases, and the outer slide rod 126 moves in the opposite direction on the inner slide rod 125, and so on.
[0044] When the outer slide rod 126 is perpendicular to the slide rail 104, the overall length of the outer slide rod 126 and the inner slide rod 125 is at its maximum, and at this time, the inner spring 130 on the middle slide rod 128 is in a compressed state. When the upper main shaft 106 rotates, the middle slide rod 128 moves away from the upper main shaft 106, thereby releasing the elastic force of the inner spring 130. The elastic force of the inner spring 130 accelerates the movement of the middle slide rod 128. When it gradually moves to the maximum distance, the outer spring 126 on the middle slide rod 128... 9. Gradually approaching and contacting the limiting block 131 on the inner slide rod 125, the upper main shaft 106 continues to rotate due to the obstruction of the limiting block 131. The intermediate slide rod 128 continues to move away from the upper main shaft 106, compressing the outer spring 129. When it reaches its maximum distance and the distance begins to decrease, the elastic force of the outer spring 129 pushes the intermediate slide rod 128. Similarly, after the inner spring 130 contacts the end of the inner slide rod 125, the continued movement of the intermediate slide rod 128 compresses the inner spring 130, and this cycle repeats. The elastic forces of the outer spring 129 and the inner spring 130 promote the change of the movement direction of the outer slide rod 126 on the inner slide rod 125.
[0045] The movement of the outer slide rod 126 on the inner slide rod 125 does not affect the connecting ring 127. The connecting ring 127 is always fixedly connected to the upper spiral plate 107. When the outer slide rod 126 moves on the inner slide rod 125, the connecting ring 127 maintains the distance between itself and the upper main shaft 106, and the outer slide rod 126 slides within the connecting ring 127. The support capacity of the end of the upper spiral plate 107 away from the upper main shaft 106 is ensured by the change in the overall length of the outer slide rod 126 and the inner slide rod 125.
[0046] like Figures 3 to 6 As shown, the connecting ring 127 is provided with two connection points, which are respectively connected to different ends of the two upper spiral plates 107.
[0047] Specifically, the upper connection point of the connecting ring 127 is connected to the lower end of the upper spiral plate 107, and the lower connection point of the connecting ring 127 is connected to the upper end of the lower spiral plate 107. Thus, the upper and lower ends of the upper spiral plate 107 are moved by the connecting rings 127 on the two support components, thereby jointly driving the upper spiral plate 107 to rotate.
[0048] like Figure 4 As shown, the upper spiral plate 107 is provided with two vertical slide rods at one end near the upper main shaft 106, and the two vertical slide rods are respectively slidably arranged on two adjacent slide grooves on the upper main shaft 106.
[0049] Specifically, the upper spiral plate 107 has a spiral structure. Two vertical rods are provided at one end of the upper spiral plate 107 near the upper main shaft 106. These vertical rods connect the upper and lower spiral ends respectively, thereby ensuring the stability of the upper spiral plate 107 structure.
[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
