Description

Technical Field

[0001] This invention relates to the field of preform conveying technology, specifically to a low-wear preform conveying device. Background Technology

[0002] In the milk filling production line, the preform is the core component of the packaging container. Its surface quality directly affects the subsequent blow molding and the appearance quality of the final product. In order to improve processing efficiency, the preform needs to be continuously conveyed by a conveying device during processing. For example, the invention disclosed in patent announcement number CN 106477240 B discloses a non-destructive bottle preform conveying device, including a frame and a conveying mechanism mounted on the frame. Several preform receiving mechanisms are provided between two rotating chains. Each preform receiving mechanism includes a support plate spanning the two rotating chains, with at least one preform receiving rod fixedly mounted on the support plate. The frame also includes a preform lifting mechanism, which includes a central lifting plate, a preform lifting rod fixedly mounted on the central lifting plate, and a second driving device capable of driving the central lifting plate to move up and down. The preform lifting rod can move upward or retract downward under the drive of the second driving device, allowing the top of the preform lifting rod to extend upward through a first through hole or retract downward through a second through hole. This invention features anti-collision, dustproof, and anti-surface friction characteristics, effectively ensuring the surface quality of the original bottle preforms, while also facilitating bottle handling and packing operations for workers, thus improving packing efficiency.

[0003] However, based on the actual use of currently used conveying devices, certain drawbacks still exist during their operation: Current conveying devices, due to the non-fixed position of the preforms, will cause wear and tear on the preforms during conveying, affecting the quality of the finished product; Commonly used conveying devices are not good at limiting the preforms. Due to the vibration when the conveying device starts and stops, the preforms or formed bottles may fall off, affecting the conveying efficiency. Therefore, we propose a low-wear preform conveying device to address the problems mentioned above. Summary of the Invention

A drive wheel is fixed to the outer side of the middle part of the drive shaft, and the outer side of the drive wheel is correspondingly engaged with the connector.

[0010] Furthermore, the drive limiting mechanism also includes an adjusting plate. The bottom of the adjusting plate is symmetrically provided with an adjusting groove in the shape of an elongated strip.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: the low-wear preform conveying device adopts a chain plate circulating conveying mechanism for preform conveying and is equipped with a pressing and limiting mechanism, which can maintain the stability of the preform, reduce preform wear, and improve processing efficiency. 1. This solution includes an inner fixing plate, an outer fixing plate, and a cross brace. The inner and outer fixing plates are separated to facilitate the installation of the overall structure and provide stable support for the conveyor belt. 2. This solution includes a straight guide plate, a curved guide plate, and a through groove. The straight guide plate and the curved guide plate are fixedly installed on the top of the base frame. Based on their internal groove structure, the conveyor belt can be limited, which helps to maintain the transmission stability of the conveyor belt. Furthermore, through grooves can be opened in the corresponding module installation positions inside the straight guide plate or the curved guide plate to facilitate air supply and connection. 3. This solution includes chain plates, clamping plates, connecting shafts, connecting heads, and connecting grooves. The chain plates are connected end to end through the connection shafts and connecting grooves. The beveled structure on the side of the connecting head and the elongated structure of the connecting groove facilitate stable conveying of the chain plates in the corner section. The chain plates are stably engaged with the straight guide plate and the curved guide plate through the clamping plate, which can prevent dislocation. 4. This solution includes a through hole, an air inlet plug, and a vertical rod. The vertical rod is fixed vertically to the top surface of the chain plate, which facilitates the direct insertion of the preform. The connection between the air inlet plug, the through hole, and the vertical rod facilitates the connection of the air passage. 5. This solution includes a drive shaft and a drive wheel, which are driven to rotate by a servo motor, facilitating the transmission of the conveyor belt through the meshing between the drive wheel and the connector. Furthermore, this solution also includes an adjusting plate, an upper pressure roller, and a lower top roller. The upper pressure roller and the lower top roller can clamp the side of the chain plate, making it easy for the clamping plate to enter the interior of the linear guide plate stably, so as to facilitate smooth conveying. 6. This solution is equipped with a first linear guide and a second linear guide. By adjusting the distance between the first and second linear guides, it is easy to limit the position of the preform or finished bottle, maintain stable conveying, and reduce transmission wear. Furthermore, this solution includes a fixed frame, a first adjusting rod, a second adjusting rod, and a fixing clamp. By adjusting the positions of the first and second adjusting rods, the position of the fixing clamp can be adjusted, thereby adjusting the positions of the first and second linear rails to facilitate use for preforms and bottles of different capacities. 7. This solution is equipped with a telescopic cylinder and a pressure head. After the material is fed through a pneumatic clamp and other mechanisms, the extension of the telescopic cylinder can directly press the preform onto the outside of the vertical rod through the pressure head. This not only maintains its stability but also increases airtightness, which is beneficial to improving the quality of the finished product. 8. This solution includes a telescopic rod, a connecting cylinder, and an air pump. The telescopic rod allows for easy raising and lowering of the connecting cylinder. When the connecting cylinder is raised, it can fit against the air inlet plug, facilitating air intake by the air pump. This allows the preform to be negatively pressured and drawn to the bottom of the vertical rod, thus pressing the preform tightly against the outside of the vertical rod. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Please see Figures 1-11 The present invention provides the following technical solution: A low-wear preform conveying device includes: a base frame 1, an inner fixed plate 11, an outer fixed plate 12, a cross brace 13, a fixed base plate 14, a guide rail 2, a linear guide plate 21, a through groove 211, a curved guide plate 22, a conveyor belt 3, a chain plate 31, a clamping plate 32, a connecting shaft 33, a connector 34, a connecting groove 35, a through hole 36, an air inlet plug 37, a vertical rod 38, a drive limiting mechanism 4, a drive shaft 41, a bearing seat 42, a servo motor 43, a drive wheel 44, and an adjustment mechanism. Section plate 45, adjusting groove 451, upper pressure roller 46, lower top roller 47, first linear guide 5, second linear guide 6, adjusting seat 7, fixing frame 71, first clamp 72, first adjusting rod 73, second clamp 74, second adjusting rod 75, fixing clamp 76, pressing mechanism 8, support frame 81, connecting frame 82, telescopic cylinder 83, pressure head 84, adsorption mechanism 9, mounting frame 91, top plate 92, telescopic rod 93, connecting cylinder 94, air pump 95 and connecting pipe 96; Among them: such as Figure 1 , Figure 2 and Figure 3 In the process, the top of the base frame 1 is equipped with a conveyor belt 3, and the guide rail 2 is fixed to the top of the base frame 1. The guide rail 2 is composed of a straight guide plate 21 and a curved guide plate 22. The top surfaces of the straight guide plate 21 and the curved guide plate 22 are provided with slots for limiting the position of the conveyor belt 3. The conveyor belt 3 is composed of chain plates 31 connected end to end. The top surface of the chain plates 31 is fixed with a vertical rod 38 for placing the preform. The top of the base frame 1 is provided with a first linear rail 5 and a second linear rail 6. The outer sides of the first linear rail 5 and the second linear rail 6 are provided with an adjusting seat 7 for adjusting the individual spacing of the first linear rail 5 and the second linear rail 6 for limiting the position of the preform.

[0019] In specific application scenarios, the preform is clamped and placed above the vertical rod 38 by the pneumatic clamping mechanical motion unit, so that the preform is inverted and the vertical rod 38 is inserted into the preform for conveying. The preform is conveyed by the conveyor belt 3. During the conveying process, the stability of the conveyor belt 3 is maintained by the engagement between the grooves opened in the straight guide plate 21 and the curved guide plate 22 and the bottom of the conveyor belt 3, so that the conveyor belt 3 will not slip. The first linear rail 5 and the second linear rail 6, which adjust the spacing and height according to the size and position of the preform, can limit and protect the side of the preform, which can improve the stability of the preform transmission and reduce wear during the transmission process.

[0020] The above technical solution facilitates the transfer and use of preforms, maintains transfer stability, and reduces wear on preforms during transfer.

[0021] Among them: such as Figure 2 , Figure 3 and Figure 4 In the frame 1, there are straight sections and angled sections. Both straight sections and angled sections are composed of inner fixing plates 11 and outer fixing plates 12. A cross brace 13 is fixedly connected between the inner fixing plate 11 and the outer fixing plate 12. A fixed base plate 14 is fixedly connected to the bottom of the inner fixing plate 11 and the outer fixing plate 12.

[0022] In specific application scenarios, the base frame 1 is composed of an inner fixed plate 11 and an outer fixed plate 12, which are fixed by a cross brace 13 and a fixed base plate 14. It can be assembled independently for overall setup, which is convenient for connection and installation. The fixed base plate 14 also facilitates the overall mounting and use of the conveyor line. The above technical solution facilitates structural loading and makes it easy to fix the whole structure in place.

[0023] Among them: such as Figure 1 , Figure 3 , Figure 8 , Figure 9 and Figure 10In the middle, a locking plate 32 is integrally fixedly connected to the bottom of the chain plate 31. The chain plate 31 is correspondingly engaged with the straight guide plate 21 and the curved guide plate 22 through the locking plate 32. A connecting shaft 33 is fixedly provided at the end of the chain plate 31. A connector 34 is integrally provided on the front side of the chain plate 31. A connecting groove 35 with a long strip structure is opened inside the connector 34. The side of the connector 34 has an inclined structure. A through hole 36 is opened through the middle of the chain plate 31. An air inlet plug 37 is fixed to the bottom surface of the chain plate 31 below the through hole 36. The air inlet plug 37, the through hole 36 and the vertical rod 38 are connected.

[0024] In specific application scenarios, the chain plate 31 is connected to the connecting head 34 and connecting shaft 33 at both ends, which facilitates the connection between the connecting shaft 33 and the connecting head 34, so as to connect the chain plate 31 end to end to form the conveyor belt 3 for conveying. At the same time, the connecting head 34 is connected to the connecting shaft 33 through the connecting groove 35 with a long strip structure, so as to facilitate the bending of the chain plate 31 individual pieces during transmission inside the curved guide plate 22, so as to facilitate stable conveying. At the same time, the bottom of the chain plate 31 is provided with a clamping plate 32, which can lock and slide the chain plate 31 in the groove inside the straight guide plate 21 and the curved guide plate 22 for stable conveying. Meanwhile, the conveyor belt 3 is provided with a through hole 36, which facilitates the connection between the air inlet plug 37, the through hole 36 and the vertical rod 38, so as to facilitate the air passage, thereby facilitating the use of air suction or bottle blowing.

[0025] By adopting the above technical solution, the connection between the first and last ends of the chain plate 31 facilitates the overall transmission and conveying of the conveyor belt 3, and the clamping plate 32 facilitates locking to maintain stability. At the same time, the connection between the through hole 36, the air inlet plug 37 and the vertical rod 38 facilitates the connection of the air passage.

[0026] Among them: such as Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9In the base frame 1, a drive limiting mechanism 4 for driving the conveyor belt 3 is fixedly installed inside. The drive limiting mechanism 4 includes a drive shaft 41, which is rotatably mounted between an inner fixed plate 11 and an outer fixed plate 12. Bearing seats 42 are fixedly mounted on the outer sides of the inner fixed plate 11 and the outer fixed plate 12. The end of the drive shaft 41 is rotatably connected inside the bearing seat 42. A servo motor 43 is connected to the outer end of the drive shaft 41. A drive wheel 44 is fixed to the outer side of the middle part of the drive shaft 41. The outer side of the drive wheel 44 is connected to... The connectors 34 are engaged with each other. The drive limiting mechanism 4 also includes an adjusting plate 45. The bottom of the adjusting plate 45 is symmetrically provided with an adjusting groove 451 in the shape of an elongated strip. The adjusting plate 45 is fixedly connected to the outer side of the inner fixing plate 11 and the outer fixing plate 12 through the adjusting groove 451. An upper pressure wheel 46 is rotatably installed on the inner side of the top of the adjusting plate 45. A lower top wheel 47 is rotatably installed on the inner side of the adjusting plate 45 below the upper pressure wheel 46. The upper pressure wheel 46 and the lower top wheel 47 are clamped on the side of the chain plate 31.

[0027] In specific application scenarios, the connection between the servo motor 43 and the drive shaft 41 facilitates the start of the drive shaft 41 to rotate inside the bearing seat 42, so as to drive the drive wheel 44 to rotate, and so as to mesh the drive wheel 44 with the connector 34 to transport the conveyor belt 3. At the same time, an adjustment plate 45 fixed to the base frame 1 is provided on the outside of the drive shaft 41. The bottom of the adjustment plate 45 has an adjustment groove 451 with a long strip structure, which facilitates the adjustment of the height position of the adjustment plate 45. After the adjustment plate 45 is fixed to the base frame 1, the upper pressure wheel 46 and the lower top wheel 47, which are rotatably installed on the inside of the adjustment plate 45, are clamped and installed on the outside of the chain plate 31, so that the upper pressure wheel 46 and the lower top wheel 47 limit the side of the chain plate 31, so as to ensure the stable transport of the chain plate 31. The above technical solution facilitates the conveying of the conveyor belt 3 via the drive shaft 41 and drive wheel 44, and the upper pressure wheel 46 and lower top wheel 47 limit the conveyor belt 3, making it easy for the chain plate 31 and the clamping plate 32 to enter the linear guide plate 21 stably, so as to maintain stable conveying.

[0028] Among them, such as Figure 1 , Figure 3 and Figure 11The adjusting seat 7 includes a fixed frame 71, a first clamp 72, a first adjusting rod 73, a second clamp 74, a second adjusting rod 75, and a fixing clamp 76. The fixed frame 71 is fixedly installed on the outer side of the base frame 1. The first clamp 72 is fixedly installed on the outer side of the fixed frame 71. The first adjusting rod 73 is telescopically connected to the end of the first clamp 72. The second clamp 74 is installed on the top of the first adjusting rod 73. The second adjusting rod 75 is telescopically connected to the end of the second clamp 74. The top of the second adjusting rod 75 is fixed with a fixing clamp 76 for limiting the first rail 5 and the second rail 6.

[0029] In specific application scenarios, the fixing frame 71 is fixed to the inner fixing plate 11 or the outer fixing plate 12 to facilitate the installation of the first clamp 72. The height is adjusted by sliding the first adjusting rod 73 inside the first clamp 72, which facilitates the height adjustment of the fixing clamp 76. At the same time, the second adjusting rod 75 slides and extends inside the second clamp 74 to adjust the position of the fixing clamp 76, which facilitates the adjustment of the clamping and fixing position of the first linear guide 5 and the second linear guide 6, thereby adjusting the distance between the first linear guide 5 and the second linear guide 6 to adapt to the preform or the finished bottle.

[0030] By adopting the above technical solution, it is easy to adjust the spacing between the first guide rail 5 and the second guide rail 6, so as to limit the preform or finished bottle, maintain stable conveying, and reduce wear on the preform or finished bottle.

[0031] Among them: such as Figure 1 , Figure 3 , Figure 6 and Figure 7 In the middle of the front side of the base frame 1, a pressing mechanism 8 is fixedly installed. The pressing mechanism 8 includes a support frame 81 fixed above the base frame 1, a connecting frame 82 fixed to the top surface of the support frame 81, and telescopic cylinders 83 fixed at equal intervals inside the connecting frame 82. A pressure head 84 is fixedly installed at the bottom end of the telescopic cylinder 83. An adsorption mechanism 9 is fixedly installed inside the front side of the base frame 1. The adsorption mechanism 9 includes a mounting frame 91 fixed inside the base frame 1. The top end of the mounting frame 91 is telescopically connected to a top plate 92 through a telescopic rod 93. Connecting cylinders 94 are evenly arranged on the top of the top plate 92. The bottom end of the connecting cylinder 94 is connected to an air suction pump 95 through a connecting pipe 96.

[0032] In specific application scenarios, the support frame 81 is fixedly installed at the top of the base frame 1. The top of the support frame 81 is extended and retracted by the telescopic cylinder 83 installed on the connecting frame 82. The pressure head 84 can press down on the bottle preform placed in the vertical rod 38, so that the pressure head 84 can press the bottle preform tightly on the outside of the vertical rod 38. The conical sealing gasket set on the bottom side of the vertical rod 38 can ensure the positioning, fixation and sealing of the bottle preform. At the same time, the extension and retraction of the telescopic rod 93 set inside the base frame 1 can raise the top plate 92, so that the connecting cylinder 94 fixed inside the top plate 92 can be connected to the air inlet plug 37, so that the air pump 95 can draw air. Through the connection between the connecting pipe 96, the connecting cylinder 94, the air inlet plug 37, the through hole 36 and the vertical rod 38, the bottle preform on the top of the vertical rod 38 can be adsorbed downward, so that the bottle preform is adsorbed and fixed on the outside of the vertical rod 38.

[0033] The above technical solution facilitates the pressing and fixing of the preform to the outside of the vertical rod 38, thereby ensuring the preform is fixed, ensuring stable conveying, reducing vibration and falling, and avoiding wear.
