Abstract

This utility model relates to the field of food processing equipment manufacturing technology, and in particular to a composite motion drive mechanism for a gluten roll winding device, which consists of a torque output unit and a drag force output unit. The winding assembly performs circumferential rotation under the drive of the torque output unit; the unloading cylinder, driven by the drag force output unit, completes axial reciprocating movement, causing the formed gluten to detach.

Thus, on the one hand, the composite motion drive mechanism has a relatively simple design structure, and thanks to the operating characteristics of the cam mechanism, the unloading cylinder can achieve non-rigid unloading force application; on the other hand, by adjusting the contour curve of the cam mechanism and the parameters of the multi-component transmission mechanism, and with the assistance of the elastic reset component, the gluten roll winding device can adapt to various unloading requirements.

Description

Technical Field

[0001] This utility model relates to the field of food processing equipment manufacturing technology, and in particular to a composite motion drive mechanism for a gluten roll winding device. Background Technology

[0002] In the food processing industry, gluten rolls, as a traditional food loved by consumers, require advanced automated production technology to improve production efficiency and product quality. Existing gluten roll winding devices typically use a winding body to stretch, thin, and compact the gluten, but traditional unwinding methods have many problems during the process of the gluten separating from the winding body after winding.

[0003] Some manufacturers have recently launched automated unloading devices, which solve the problem of low efficiency in manual unloading. However, the design relying on a single linear drive mechanism to move the unloading component axially back and forth still has significant technical bottlenecks. Taking the lead screw and nut structure as an example, to ensure that the unloading component moves smoothly along a straight line during the unloading process, a high-precision linear guide rail is required as a guiding component. It also needs to be equipped with photoelectric limit switches and a microcontroller control system to monitor and adjust the position and speed of the unloading component in real time. Similarly, devices using cylinder drives require sophisticated solenoid valve groups, air pressure stabilization systems, and displacement sensors to control the cylinder's extension and retraction stroke and speed. This not only makes the equipment design complex but also significantly increases its manufacturing cost, maintenance difficulty, and failure rate.

[0004] It should also be noted that, at the moment of gluten ejection, the unidirectional impact force generated by the single linear drive mechanism can easily damage the integrity of the gluten structure, leading to problems such as surface tearing and deformation. Therefore, those skilled in the art urgently need to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a composite motion drive mechanism for a gluten roll winding device to solve the problems existing in the prior art.

[0006] This utility model relates to a composite motion drive mechanism for a gluten roll winding device, comprising a torque output unit and a drag force output unit, adapted to a gluten roll winding device including a winding assembly and an unwinding cylinder. Under the action of the torque output unit, the winding assembly performs circumferential rotational motion, achieving stretching, thinning, and layer-by-layer compaction of the gluten. The unwinding cylinder is fitted around the winding assembly and, driven by the drag force output unit, performs axial reciprocating movement, causing the wound gluten to detach.

[0007] The drag force output unit includes:

[0008] The drive shaft serves as the power input source;

[0009] A cam mechanism, which is powered by a drive shaft, is used to convert the power transmitted by the drive shaft into a driving force to drive a multi-component transmission mechanism.

[0010] The swing component has its two ends hinged to the frame and the unloading cylinder, respectively;

[0011] The elastic reset component applies an elastic reset force to the rocker component;

[0012] The multi-component transmission mechanism serves as the transmission hub between the cam mechanism and the rocker component. When the cam mechanism is driven by the transmission shaft, it is supplemented by an elastic reset component, which drives the rocker component to perform reciprocating rocking motion through the multi-component transmission mechanism, allowing the unloading cylinder to synchronously achieve axial reciprocating motion.

[0013] As a further improvement to the technical solution disclosed in this utility model, the cam mechanism includes a cam and a follower. The cam is fixedly connected to the transmission shaft and rotates synchronously.

[0014] The multi-component transmission mechanism includes a reciprocating drive swing arm, a first link, a reciprocating swing frame, a second link, and a first connecting plate assembly that are sequentially hinged.

[0015] One end of the reciprocating drive swing arm forms a revolute joint with the frame via a pivot and serves as the mounting carrier for the driven component. The first connecting plate assembly is hinged to the swing component to form a revolute joint.

[0016] As a further improvement to the technical solution disclosed in this utility model, the follower is a roller-type follower. The outer peripheral surface of the follower forms a rolling contact with the contour curve of the cam.

[0017] As a further improvement to the technical solution disclosed in this utility model, the reciprocating swing arm includes a first swing arm, a rotating sleeve, and a second swing arm. The first swing arm and the second swing arm are respectively hinged to the first connecting rod and the second connecting rod, and both are welded and fixed to the rotating sleeve. The rotating sleeve performs a fixed-axis circumferential rotational motion under the action of rotational torque.

[0018] As a further improvement to the technical solution disclosed in this utility model, the reciprocating swing arm also includes an auxiliary reinforcing arm. The auxiliary reinforcing arm is connected between the first swing arm and the second swing arm.

[0019] As a further improvement to the technical solution disclosed in this utility model, the first tilting arm is provided with mounting holes, which allow it to be hinged to the first connecting rod. There are multiple mounting holes, arranged linearly along the direction of the line connecting the hinge points.

[0020] As a further improvement to the technical solution disclosed in this utility model, the drag force output unit also includes a limit position limiting component. With the assistance of the limit position limiting component, the upper swing limit angle of the reciprocating drive swing arm is limited.

[0021] As a further improvement to the technical solution disclosed in this utility model, the limit position limiting component includes a support seat, a vertical screw, and a rubber column. The support seat is welded and fixed to the frame and serves as the mounting base for the vertical screw. The rubber column is used to apply an elastic reaction force to the reciprocating drive arm and is fixedly connected to the free end of the vertical screw.

[0022] As a further improvement to the technical solution disclosed in this utility model, the elastic reset assembly includes a load-bearing component and a first transmission screw, a tension spring, a second transmission screw, and a second connecting plate assembly connected in sequence. The load-bearing component is welded and fixed to the frame and serves as the mounting base for the first transmission screw. The second connecting plate assembly is hinged to the rocker component.

[0023] As a further improvement to the technical solution disclosed in this utility model, the torque output section includes a synchronous belt drive mechanism. The synchronous belt drive mechanism includes a driving pulley, a driven pulley, and a synchronous belt. The driven pulley engages with the driving pulley via the synchronous belt, thereby applying torque to the winding assembly.

[0024] In practical applications, the composite motion drive mechanism of the gluten winding device disclosed in this utility model can achieve at least the following beneficial technical effects, specifically:

[0025] 1) The drag force output unit is a drive system composed of a drive shaft, cam mechanism, multi-component transmission mechanism, swing component, and elastic reset component, enabling precise axial reciprocating movement of the unloading cylinder. Furthermore, the drag force output unit features a minimalist design structure, effectively reducing manufacturing costs, equipment maintenance difficulty, and failure rate, thus ensuring the stability of equipment operation.

[0026] 2) Thanks to the driving characteristics of the cam mechanism, it can make the unloading cylinder move smoothly and stably in the axial direction when driving the rocking component. This achieves non-rigid force application in the unloading process, which can avoid damage to the gluten body due to uneven force and help improve the integrity and appearance quality of the gluten roll product.

[0027] 3) By adjusting the profile curve of the cam mechanism and the parameters of the multi-component transmission mechanism, and combining the adaptive adjustment of the elastic reset component, the gluten winding device can adapt to the unloading requirements under different working conditions. Whether dealing with gluten raw materials with different humidity and viscosity, or coordinating with different rotation speeds of the winding assembly, the composite motion drive mechanism can precisely control the movement trajectory and speed of the unloading cylinder to achieve efficient coordination with the winding assembly.

Detailed Implementation

[0037] In the description of this utility model, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 A three-dimensional schematic diagram of the gluten winding system disclosed in this utility model is shown. It can be seen that it mainly consists of two parts: a gluten winding device 1 and a composite motion drive mechanism 2. The gluten winding device 1 includes a winding assembly 11 and a feed cylinder 12. The feed cylinder 12 is fitted around the winding assembly 11 (e.g., ...). Figure 2 (As shown in the diagram). The composite motion drive mechanism 2 includes a torque output unit 21 and a drag force output unit 22. During operation, the torque output unit 21 is activated first, precisely transmitting power to the winding assembly 11 to drive it to perform circumferential rotation, so that the gluten body can be gradually stretched and thinned, and layer-by-layer compacting can be achieved; subsequently, the drag force output unit 22 is activated to drive the unloading cylinder 12 to perform axial displacement, so that the gluten body can be detached from the winding assembly 11.

[0039] like Figure 3As shown, the torque output unit 21 mainly consists of a motor 211, a chain drive mechanism 212, and a synchronous belt drive mechanism 213. The motor 211 serves as the power source, outputting rotational power. The chain drive mechanism 212 transmits and increases power at a high transmission ratio by meshing the chain with the sprocket. Subsequently, the synchronous belt drive mechanism 213 utilizes the synchronous belt 2133 to precisely mesh with the driving pulley 2131 and the driven pulley 2132, achieving slip-free synchronous transmission. This precisely transmits power to the winding assembly 11, ensuring its stable rotation and enabling high-precision forming of the gluten body.

[0040] like Figure 4 As shown, the drag force output unit 22 mainly consists of several parts, including a drive shaft 221, a cam mechanism 222, a multi-component transmission mechanism 223, a rocker element 224, and an elastic reset component 225. The drive shaft 221 serves as the power input source. The cam mechanism 222 converts the power transmitted by the drive shaft 221 into a driving force for the multi-component transmission mechanism 223, and includes a cam 2221 and a follower 2222. The cam 2221 is fixedly connected to the drive shaft 221 and rotates synchronously. The lower end of the rocker element 224 is hinged to the frame, while its upper end is hinged to the unloading cylinder 12. The elastic reset component 225 is mounted on the frame and directly applies an elastic reset force to the rocker element 223. The multi-component transmission mechanism 223 serves as the transmission hub between the cam mechanism 222 and the rocker element 224.

[0041] During the operation of the gluten roll winding system, the drag force output unit 22 uses the drive shaft 221 as a power source to drive the cam 2221, which is fixedly connected to it, to rotate synchronously. At the same time, the driven member 2222, which is in contact with the cam 2221, performs a regular lifting and lowering motion. The driven member 2222 transmits the driving force to the multi-component transmission mechanism 223, and after conversion, drives the rocker member 224 to perform a reciprocating rocking motion, driving the unloading cylinder 12 to move axially back and forth synchronously. In this process, the rocker member 224 resets itself due to the elastic force from the elastic reset component 225 to prepare for the next unloading action.

[0042] By adopting the above technical solution, on the one hand, the drag force output unit 22 is a drive system composed of a drive shaft 221, a cam mechanism 222, a multi-component transmission mechanism 223, a rocker component 224, and an elastic reset component 225, enabling the unloading cylinder 12 to achieve precise axial reciprocating movement. Furthermore, the drag force output unit 22 has a minimalist design structure, which not only effectively reduces manufacturing costs but also lowers equipment maintenance difficulty and failure rate, ensuring the stability of equipment operation. On the other hand, thanks to the driving characteristics of the cam mechanism 222, it can drive the rocker component 224 to move, enabling the unloading cylinder 12 to achieve smooth and stable axial reciprocating movement. This achieves non-rigid force application during the unloading process, avoiding damage to the gluten body due to uneven force distribution, and improving the integrity and appearance quality of the gluten roll product.

[0043] Here, it is also important to emphasize that, in practical applications, by adjusting the contour curve of the cam mechanism 222 and the parameters of the multi-component transmission mechanism 223, and combining the adaptive adjustment of the elastic reset component 225, the gluten winding device 1 can adapt to the unloading requirements under different working conditions. Whether dealing with gluten raw materials of different humidity and viscosity, or coordinating with different rotational speeds of the winding assembly 11, the composite motion drive mechanism 2 can precisely control the movement trajectory and speed of the unloading cylinder 12 to achieve efficient coordination with the winding assembly 11.

[0044] As described above, the multi-component transmission mechanism 223 is used to convert the planar motion of the cam mechanism 222 into the linear motion of the unloading cylinder 12, thereby achieving efficient power transmission and motion form conversion. As a further refinement of the above technical solution, such as... Figure 4 As shown, the multi-component transmission mechanism 223 includes a reciprocating drive swing arm 2231, a first connecting rod 2232, a reciprocating yaw frame 2233, a second connecting rod 2234, and a first connecting plate assembly 2235, which are sequentially hinged. The rear end of the reciprocating drive swing arm 2231 forms a revolute joint with the frame via a pivot and serves as the mounting carrier for the driven member 2222, while its front end is hinged to the first connecting rod 2232. The first connecting plate assembly 2235 is hinged to the yaw member 224 to form a revolute joint. When the driven member 2222 performs a lifting motion under the drive of the cam 2221, it drives the reciprocating drive swing arm 2231 to perform a reciprocating yaw motion around the pivot, and transmits this motion to the reciprocating yaw frame 2233 via the first connecting rod 2232, causing it to produce a yaw motion. The sway of the reciprocating sway frame 2233 is then transmitted to the first connecting plate assembly 2235 via the second connecting rod 2234, which ultimately drives the swaying component 224 to achieve reciprocating swaying, thereby driving the unloading cylinder 12 to complete axial reciprocating movement.

[0045] In practical applications, by rationally designing the lengths and hinge points of each stage of the connecting rods (including the reciprocating drive swing arm 2231, the first connecting rod 2232, the reciprocating deflector frame 2233, the second connecting rod 2234, and the first connecting plate assembly 2235), the motion trajectory and speed curve of the unloading cylinder 12 can be precisely controlled, thereby facilitating non-uniform motion and effectively preventing the gluten body from being damaged by rigid impact forces.

[0046] like Figure 5 As shown, the reciprocating oscillating frame 2233 includes a first oscillating arm 22331, a rotating sleeve 22332, a second oscillating arm 22333, and an auxiliary reinforcing arm 22334. The first oscillating arm 22331 and the second oscillating arm 22333 are respectively hinged to the first connecting rod 2232 and the second connecting rod 2234, and both are fixed by welding through the rotating sleeve 22332, and connected by the auxiliary reinforcing arm 22334 to form a triangular stable structure. The first oscillating arm 22331 is provided with a mounting hole 223311, which allows it to be hinged to the first connecting rod 2232. The rotating sleeve 22332 performs a fixed-axis circumferential rotational motion under the action of rotational torque. In this way, under the premise that the design strength of the reciprocating oscillating frame 2233 is guaranteed, and it can convert the linear driving force into a compound oscillating motion, it is beneficial to achieve precise control of the axial reciprocating trajectory of the unloading cylinder 12.

[0047] Similarly, Figure 5 As shown, there are three mounting holes 223311, arranged linearly along the direction of the hinge point connection. In this way, when the gluten winding equipment needs to fine-tune its motion parameters in different working scenarios, the hinge point position between the first connecting rod 2232 and the first swing arm 22331 can be changed by switching the mounting holes, thereby adjusting the starting angle and stroke range of the entire reciprocating swing frame 2233.

[0048] like Figure 6As shown, the elastic reset assembly 225 includes a load-bearing component, a first transmission screw 2251, a tension spring 2252, a second transmission screw 2253, and a second connecting plate assembly 2254. The load-bearing component is welded and fixed to the frame and serves as the mounting base for the first transmission screw 2251 (not shown in the figure). The first transmission screw 2251, tension spring 2252, second transmission screw 2253, and second connecting plate assembly 2254 are sequentially connected, and the second connecting plate assembly 2254 is hinged to the rocker component 224. In actual operation, when the rocker component 224 performs reciprocating rocking motion under the drive of the multi-component transmission mechanism 223, the tension spring 2252 stores elastic potential energy due to tensile deformation. When the direction of the driving force of the multi-component transmission mechanism 223 on the rocker member 224 changes, the elastic potential energy stored in the tension spring 2252 is released and transmitted to the rocker member 224 via the second transmission screw 2253 and the second connecting plate assembly 2254, so that the rocker member 224 can reset itself.

[0049] like Figure 4 As shown, the drag force output unit 22 is also equipped with a limit position limiting component 226. With the assistance of the limit position limiting component 226, the upward swing limit angle of the reciprocating drive swing arm 2231 is limited. Figure 7 As shown, the limit position limiting component 226 includes a support seat 2261, a vertical screw 2262, and a rubber post 2263. The support seat 2261 is welded and fixed to the frame and serves as the mounting base for the vertical screw 2262. The rubber post 2263 is used to apply an elastic reaction force to the reciprocating drive swing arm 2231 and is fixedly connected to the free end of the vertical screw 2262. In this way, it effectively prevents the reciprocating drive swing arm 2231 from exceeding the design range due to excessive swing angle, which could lead to collisions, deformations, or damage to related components. It also avoids instantaneous impacts on the multi-component transmission mechanism 223 and the swing member 224 due to excessive movement, ensuring the smoothness and reliability of the power output process of the drag force output unit 22.

[0050] In actual operation, when the reciprocating drive swing arm 2231 performs yaw motion under the driving force from the multi-component transmission mechanism 223 and approaches the preset limit angle, the reciprocating drive swing arm 2231 contacts and compresses the rubber column 2263. The rubber column 2263 elastically deforms to generate a reaction force, preventing the reciprocating drive swing arm 2231 from continuing to yaw upward, thereby achieving the limit angle limitation of the upward yaw.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
