Abstract
Description
Technical Field
[0001] This utility model relates to the field of recombinant cell manufacturing, and in particular to a recombinant cell impregnation device. Background Technology
[0002] In the production and processing equipment of reconstituted materials, especially in equipment involving critical processes such as pressing and conveying, a highly efficient and reliable transmission system is crucial. Such equipment typically requires driving multiple sets of pressure rollers to work together. Traditional transmission solutions often employ a single belt drive or pure gear drive, and the power input point is often located at one end of the system (end-drive mode). This mode has significant technical drawbacks:
[0003] (1) When power is input from one end, there is a significant difference in the length of the transmission belt between the pressure roller group closer to the power source and the pressure roller group farther away. This length difference will cause the torque actually received by each pressure roller group to be inconsistent, which can easily cause vibration and increased noise in the transmission system, affecting the smoothness of equipment operation and processing accuracy.
[0004] (2) For the pressure roller group that is far from the power input end, the transmission path is too long and the load on the transmission belt is greater. Especially under high load and continuous operation conditions, it is easy to cause excessive stretching of the transmission belt, accelerated wear, shorten service life, increase maintenance costs and downtime risk.
[0005] (3) In order to achieve multi-stage transmission or power distribution, traditional designs often require the introduction of additional drive shafts, idler gears or complex gear systems. This not only increases the complexity of the system, but also significantly increases the lateral installation space of the equipment, which is not conducive to the miniaturization and compact design of the equipment, especially for factories with limited space or equipment that requires high integration.
[0006] Therefore, there is an urgent need to develop a new type of transmission component suitable for scenarios such as recombinant material processing, which can effectively solve problems such as uneven power distribution, rapid wear of transmission belts, and large operating vibration while simplifying the structure and reducing space, so as to meet the needs of high-performance, compact, and highly reliable equipment.

Detailed Implementation
[0069] To make the technical problem to be solved, the technical solution and advantages of this utility model clearer, the following will be described in conjunction with the accompanying drawings. Figures 1 to 16 The technical solution of this utility model is clearly and completely described in conjunction with specific embodiments.
[0070] The recombination unit impregnation device 100 of this utility model includes: a frame 110, a glue tank 120, an impregnation roller assembly 130, a rotary drive device 140, and a rotary transmission assembly 150.
[0071] The frame 110 provides a solid foundation support for the glue tank 120, the glue dipping roller assembly 130, the rotary drive device 140, and the rotary transmission assembly 150, ensuring the rigidity and stability of the equipment during the extrusion process.
[0072] The glue tank 120 is mounted on the frame 110. The glue solution used for impregnation is in the glue tank 120.
[0073] At least three dip roller assemblies 130 are provided, and all dip roller assemblies 130 are sequentially arranged on the frame 110 along the conveying direction of the sheet material. Each dip roller assembly 130 includes: a frame 131 fixed to the frame 110; an upper rotating shaft 132, both ends of which are connected to the frame 131 via bearings; a lower rotating shaft 133, both ends of which are connected to the frame 131 via bearings; an upper rotating roller 134 coaxially fixed to the upper rotating shaft 132; a lower rotating roller 135 coaxially fixed to the lower rotating shaft 133; and a gear disk assembly 136, including an upper gear disk 136a coaxially fixed to the upper rotating shaft 132 and located outside the frame 131, and a lower gear disk 136b coaxially fixed to the lower rotating shaft 133 and meshing with the upper gear disk 136a. The upper gear disk 136a and the lower gear disk 136b are located outside the frame 131.
[0074] The upper roller 134 and the entire lower roller 135 of the dip roller assembly 130 are located in the glue solution in the glue tank 120, and the reconstitution unit achieves extrusion dip through the upper roller 134 and the lower roller 135.
[0075] The upper gear disk 136a is fixed to the upper rotating shaft 132, and the lower gear disk 136b is fixed to the lower rotating shaft 133, and the two are always in a meshed state. Regardless of the height of the upper rotating roller 134 (i.e., regardless of the change in the roller gap), the meshing gear disks forcefully ensure that the upper rotating roller 134 and the lower rotating roller 135 rotate in opposite directions at exactly the same linear velocity (rotation speed). When the reconstituted unit material is conveyed between the upper and lower rollers, if the speeds of the two rollers are inconsistent, it will cause the material to be stretched, wrinkled, or even torn. Forced synchronization completely eliminates this risk. Speed synchronization ensures that the traction force and impregnation effect on the material in the roller gap are consistent, thereby obtaining a uniform adhesive coating. Only one impregnation roller shaft (lower rotating shaft 133) needs to be driven to drive the other impregnation roller shaft (upper rotating shaft 132) to rotate synchronously through gear meshing. There is no need to configure a complex floating drive mechanism (such as universal coupling, transmission belt tension adjustment mechanism, etc.) for the upper roller, which simplifies the design and cost of the drive system.
[0076] In a specific embodiment, the upper gear disk 136a and the lower gear disk 136b are disposed on the outside of the frame 131.
[0077] A rotary drive device 140, mounted on the frame 110, provides rotary driving force to the first rotary transmission assembly 150. The rotary drive device 140 is a device capable of outputting rotation, such as a motor, engine, hydraulic motor, or a combination of one of these with a reducer. In this embodiment of the present invention, the rotary drive device 140 comprises a servo motor 141 and a reducer 142 connected to the servo motor 141 via a belt.
[0078] The rotary transmission assembly 150 connects the rotary drive device 140 and the dip roller assembly 130. The rotary transmission assembly 150 is a belt drive or chain gear drive assembly, connected to the reducer 142 and driven by the lower rotating shaft 133.
[0079] This utility model provides a rotary transmission assembly 150, specifically including: a drive gear 151, which is disposed at the output end of the reducer 142 of the rotary drive device 140; the drive gear 151 directly meshes with the lower gear disk 136b of two adjacent dipped roller assemblies 130; a first driven wheel 152 and a second driven wheel 153 are coaxially disposed at the end of the lower rotating shaft 133 and located outside the lower gear disk 136b; the dipped roller assemblies 130 not directly meshed with the drive gear 151 achieve linkage transmission through the first driven wheel 152, the second driven wheel 153 at the end of the lower rotating shaft 133 of the adjacent assemblies and the transmission belt 154 surrounding them.
[0080] In a specific embodiment, the first driven wheel 152 and the second driven wheel 153 are sprockets, and the transmission belt 154 is a chain that matches the first driven wheel 152 and the second driven wheel 153. It is suitable for high torque scenarios and is matched with the sprockets.
[0081] In a specific embodiment, the first driven pulley 152 and the second driven pulley 153 are synchronous pulleys, and the transmission belt 154 is a synchronous belt that matches the first driven pulley 152 and the second driven pulley 153. It is suitable for scenarios that require noise reduction and anti-slip, and is matched with the synchronous pulleys.
[0082] In this embodiment of the utility model, such as Figures 3 to 8 As shown, five sets of dip roller assemblies 130 are arranged sequentially from front to back. The drive gear 151 directly meshes with the first lower gear disk 136b of the third and fourth sets of dip roller assemblies 130, respectively. The dip roller assemblies 130 not directly meshed with the drive gear 151 are linked and driven by the first driven wheel 152, the second driven wheel 153, and the transmission belt 154. Between the first and second sets of dip roller assemblies 130, the transmission belt 154 is on the first driven wheel 152 of each dip roller assembly 130; between the second and third sets of dip roller assemblies 130, the transmission belt 154 is on the second driven wheel 153 of each dip roller assembly 130; between the fourth and fifth sets of dip roller assemblies 130, the transmission belt 154 is on the second driven wheel 153 of each dip roller assembly 130.
[0083] The drive gear 151 directly drives two adjacent sets of dipped roller assemblies 130 to form the main transmission core, ensuring high torque output and avoiding single-point drive overload; the drive gear 151 directly meshes with the first lower gear disk 136b to provide a reference speed, and the transmission belt 154 linkage group follows synchronously, avoiding speed deviation caused by excessively long transmission belts in multi-roller groups.
[0084] The first rotary transmission assembly 150 adopts a hybrid drive mode of "direct meshing-stage belt drive," which simplifies the structure while achieving efficient power distribution. The drive gear 151 drives the two sets of pressure rollers in the middle position, placing the power input in the middle of the system, reducing the difference in length between the two sides of the transmission belt, and reducing vibration caused by uneven torque transmission. The middle drive mode distributes the load on the transmission belt, avoiding the problem of transmission belt wear caused by excessively long transmission paths at the end pressure rollers. In addition, the first lower gear disc 136b, the first driven pulley 152, and the second driven pulley 153 are coaxially fixed to the end of the lower rotating shaft 133, eliminating the need for an additional transmission shaft, compressing the lateral installation space, and making it suitable for compact equipment.
[0085] The recombination unit is subjected to multiple continuous compression impregnations by at least three impregnation roller assemblies 130 arranged sequentially along the conveying direction, ensuring that the adhesive can fully and uniformly penetrate into the internal structure of the recombination unit. Part of the upper roller 134 and the entire lower roller 135 are located in the adhesive in the adhesive pool 120, ensuring that the recombination unit remains in contact with the adhesive throughout the entire impregnation process.
[0086] The recombination unit impregnation device 100 provided in this embodiment is suitable for industrial impregnation equipment that requires precise control of impregnation process parameters (such as pressure and roller gap) and ensures the synchronicity of material delivery.
[0087] In a specific embodiment, the frame 131 includes: a first side plate 131a and a second side plate 131b disposed opposite to each other, fixed on the frame 110; and two sliding plates 131c, which are respectively slidably disposed with respect to the first side plate 131a and the second side plate 131b. The two ends of the upper rotating shaft 132 are respectively connected to the two sliding plates 131c via bearings. The sliding plates 131c on the first side plate 131a and the second side plate 131b drive the upper rotating roller 134 to move towards or away from the lower rotating roller 135. The extrusion gap formed by the corresponding upper and lower rotating rollers applies controllable pressure to the recombination unit, which not only promotes adhesive penetration but also squeezes out air from inside the recombination unit, preventing air bubbles from causing uneven adhesive impregnation.
[0088] The robust frame, sliding plate guides, and bearing supports provide the necessary rigidity, stability, and reliability for the entire assembly's operation (especially lifting and rotation). The bearings ensure smooth, low-friction rotation of both upper and lower roller shafts, allowing for radial loads (primarily material pressure and gear meshing forces) while permitting a degree of axial float or positioning. This is fundamental to ensuring the long-term stable operation of the equipment.
[0089] Furthermore, the dip roller assembly 130 also includes a lifting drive assembly 137, which is disposed on the frame 131 and connected to the slide plate 131c; the lifting drive assembly 137 drives the slide plate 131c to move up and down, thereby causing the upper roller 134 to move toward or away from the lower roller 135.
[0090] The linear drive source of the lifting drive assembly 137 includes, but is not limited to, linear drive components such as cylinders, hydraulic cylinders, and electric actuators, as long as they can provide linear driving force. The output end of the linear drive source is connected to the slide plate to transmit the force. In some specific embodiments, the frame 131 also includes an upper horizontal plate 131d, the two ends of which are fixed to the top ends of the first side plate 131a and the second side plate 131b, respectively. The specific composition and structure of the lifting drive assembly 137 will be described in detail below.
[0091] The lifting drive assembly 137 includes a lifting drive motor 137a, two transmission housings 137b, a worm gear, a lead screw 137c, and a synchronous shaft. The two transmission housings 137b are symmetrically fixed above the upper horizontal plate 131d, and each transmission housing 137b contains a worm gear. The worm gear in one of the transmission housings 137b is directly connected to the output shaft of the lifting drive motor 137a via a coupling, providing power input. Within each transmission housing 137b, the worm gear meshes with the worm and is threaded onto the outside of the lead screw 137c. When the worm gear rotates, it drives the lead screw 137c to move axially up and down, without rotating itself. The top end of the lead screw 137c passes through through holes in both the transmission housing 137b and the upper horizontal plate 131d, forming a sliding fit with the through holes; its bottom end is fixedly connected to the sliding plate 131c, thereby driving the sliding plate 131c to achieve the lifting function. To achieve synchronous rotation of the worm gears on both sides, this assembly also includes a synchronous shaft 137d. Both ends of the synchronous shaft 137d are connected to the worm gears within the two transmission housings 137b via couplings, ensuring that the worm gears on both sides maintain synchronous rotation. Because the worm wheel and worm gear employ a self-locking threaded engagement, the lead screw 137c automatically maintains its position after being raised or lowered to the designated position, preventing displacement due to external forces. This structural design not only achieves stable lifting and lowering but also ensures the synchronicity of the dual-side drive through the synchronous shaft, while utilizing the self-locking characteristics of the worm wheel and worm gear to guarantee the positional stability of the equipment in a static state.
[0092] The lifting drive motor 137a drives the worm gear to rotate, which in turn drives the worm wheel to rotate, causing the lead screw 137c to move up and down axially, which in turn drives the slide plate 131c to move up and down. The position of the slide plate 131c is determined based on the operating speed of the lifting drive motor 137a and the mechanical transmission ratio. The displacement of the slide plate 131c can be controlled using open-loop control: the lifting drive motor 137a uses a stepper motor or a servo motor (without encoder feedback), and the position is calculated using the following parameters: motor speed (known), running time (timing), mechanical transmission ratio (worm gear reduction ratio + lead screw lead), and initial position (e.g., zero point). The displacement of the slide plate 131c is then calculated using the following formula:
[0093] Displacement = Motor speed × Time × Lead screw lead / Transmission ratio.
[0094] The displacement of the 131c slide can also be controlled in a closed loop. The system is equipped with an encoder, grating ruler or limit switch. The displacement of the 131c slide can be directly calibrated by sensor signals without relying on theoretical calculations.
[0095] Furthermore, the lifting drive assembly 137 also includes a pressure sensor 137e, which is fixed to the top of the slide plate 131c and fixedly connected to the lead screw 137c. The pressure sensor 137e and the linear drive source are electrically connected to the controller. The controller is a microcontroller or a PLC controller.
[0096] The controller individually controls the lifting drive motor 137a of each dip roller assembly 130. The distance between the upper roller 134 and lower roller 135 of the rear dip roller assembly 130 is equal to or less than the distance between the upper roller 134 and lower roller 135 of the front dip roller assembly 130, thereby achieving dynamic adjustment of the inter-roller pressure of the dip roller assembly 130. The distance between the upper roller 134 and lower roller 135 of the rear dip roller assembly 130 is less than the distance between the upper roller 134 and lower roller 135 of the front dip roller assembly 130, maintaining a pressure state of lower pressure in the front and higher pressure in the rear, gradually increasing the pressure to improve the dip coating effect.
[0097] The dip roller assembly 130 also includes a slide plate stroke control mechanism 138. The slide plate stroke control mechanism 138 includes a positioning block 138a disposed on the outside of the slide plate 131c. An upper limit switch 138b and a lower limit switch 138c are disposed on the first side plate 131a or the second side plate 131b, respectively. The upper limit switch 138b and the lower limit switch 138c are electrically connected to the controller. When the upper limit switch 138b detects the positioning block 138a, it corresponds to the position where the gears of the upper gear disk 136a and the lower gear disk 136b disengage (i.e., the maximum thickness of the recombination unit during dip roller impregnation), preventing the transmission gears of the upper gear disk 136a and the lower gear disk 136b from disengaging and causing the upper roller 134 to lose power when it rises. When the lower limit switch 138c detects the positioning block 138a, the surfaces of the upper roller 134 and the lower roller 135 are in contact. The height position of the positioning block 138a when the surfaces of the upper roller 134 and the lower roller 135 are in contact can be regarded as the origin coordinate. At this position, the distance between the upper roller 134 and the lower roller 135 is 0, which serves as the reference for adjusting the height of the upper roller 134. In this embodiment of the invention, the upper limit switch 138b and the lower limit switch 138c are disposed on the first side plate 131a, and the upper limit switch 138b and the lower limit switch 138c are fixedly connected to the first side plate 131a through a bracket.
[0098] The upper limit switch 138b and lower limit switch 138c can be contact-type limit switches, specifically direct-acting switches. The positioning block 138a presses the upper limit switch 138b and lower limit switch 138c to trigger the control action. Alternatively, the upper limit switch 138b and lower limit switch 138c can be non-contact limit switches, including ultrasonic switches and photoelectric switches. Preferably, the upper limit switch 138b and lower limit switch 138c are photoelectric switches, capable of accurately detecting the positioning block 138a's arrival and departure.
[0099] Specifically, according to the aforementioned glue-impregnation and discharging system for the recombining unit, the glue tank 120 includes a left side plate 121 and a right side plate 122 aligned together. A roller sealing plate 123 is also provided on the left side plate 121 and the right side plate 122. The roller sealing plate 123 has a through hole 123a, providing a channel for the rotating shaft to pass through. A ring 123b is provided on the side of the through hole 123a, and a sealing ring is provided inside the ring 123b. The ring 123b provides a chamber for accommodating and fixing the sealing ring, preventing glue leakage at the connection point. The lower rotating shaft 133 passes through the through hole 123a of the roller sealing plate 123 and is sealed and connected to the sealing ring inside the ring 123b. The sealing ring tightly wraps around the rotating lower shaft 133, forming an effective dynamic sealing barrier between the shaft and the ring sleeve / roller sealing plate. The structural combination design prevents the glue in the glue pool from leaking outward along the gap between the shaft and the through hole, ensuring the stability of the glue composition and the uniformity of the glue impregnation depth.
[0100] Furthermore, the glue tank 120 also includes a limiting block 124, which is disposed inside the left side plate 121 and the right side plate 122. The height of the limiting block 124 is between the upper rotating roller 134 and the lower rotating roller 135. The setting of the limiting block 124 ensures that the recombination unit is always between the upper rotating roller 134 and the lower rotating roller 135 during the transfer of the recombination unit glue impregnation device 100, thus ensuring the uniformity of glue impregnation of the recombination unit.
[0101] Furthermore, transition connectors 125 are provided on the outer sides of the left side plate 121 and the right side plate 122 of the glue tank 120. The transition connectors 125 are formed by bending steel plates, with one end fixedly connected to the corresponding left side plate 121 or right side plate 122, and the other end fixedly connected to the frame 131. By providing the transition connectors 125, the glue tank 120 and the dipping roller assembly 130 are stably connected. In this embodiment, the transition connectors 125 on both sides of the glue tank 120 are fixedly connected to the first side plate 131a and the second side plate 131b of the frame 131 by bolts.
