Description

Technical Field

[0001] This utility model belongs to the field of instant noodle processing technology, and more specifically, it relates to a noodle-pulling rod transmission system with automatic tension adjustment. Background Technology

[0002] In the instant noodle production process, the noodle cake needs to be pushed into the variable pitch track and the sliding chute by a noodle-pulling rod to achieve precise docking with the subsequent sealing, bowl filling or bagging equipment. The noodle-pulling rod transmission system drives the chain to rotate through the rotation of the sprocket. The noodle-pulling rod is fixed on the outside of the chain, so that the noodle-pulling rod moves with the movement of the chain, pushing the noodle cake to the designated position. The existing noodle-pulling rod transmission system generally consists of a sprocket, a chain and the noodle-pulling rod responsible for execution.

[0003] Based on the above, after long-term operation, the chain of the noodle-pulling rod transmission system is prone to abnormal tension due to wear, fatigue deformation, and other factors. When the chain is loose, it is easy to cause tooth skipping and transmission slippage. When the chain is too tight, it will aggravate the frictional wear of the sprocket, chain, and related transmission components. Most existing methods for adjusting chain tension are achieved by disassembling chain links. Not only is the disassembly operation cumbersome, time-consuming, and labor-intensive, but the meshing accuracy of the sprocket and chain also needs to be repeatedly calibrated when reinstalling the chain. This makes the operation difficult and greatly affects the continuous and stable operation of the instant noodle production line. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a noodle-pulling rod transmission system with automatic tension adjustment. This solves the problem that existing noodle-pulling rod transmission systems, after prolonged operation, are prone to abnormal chain tension due to wear, fatigue, and deformation. When the chain is loose, it easily causes tooth skipping and transmission slippage; when the chain is too tight, it exacerbates frictional wear on the sprocket, chain, and related transmission components. Existing methods for adjusting chain tension mostly involve disassembling chain links, which is not only cumbersome and time-consuming, but also requires repeated calibration of the sprocket and chain meshing accuracy during reinstallation, making the operation difficult and significantly impacting the continuous and stable operation of the instant noodle production line.

[0005] The purpose and function of this utility model, which has an automatic tension adjustment lever transmission system, are achieved by the following specific technical means:

[0006] A toggle lever transmission system with automatic tension adjustment includes a mounting plate, fixed sprockets, chain boxes, a chain, a toggle lever, a guide rail, a fixed box, a positioning hole, a tension adjustment component, and a maintenance positioning component. Three fixed sprockets are rotatably connected to the front of the mounting plate. Two chain boxes are fixedly connected to the front of the mounting plate. The chain meshes with the three fixed sprockets and passes through the interior of the two chain boxes. The toggle lever is fixedly connected to the rear of the chain. The guide rail is fixedly connected to the front of the mounting plate. The fixed box is fixedly connected to the front of the mounting plate, and a square slot is formed at the front end of the fixed box. The positioning hole is located at the front end of the fixed box. The tension adjustment component is located at the front of the mounting plate. The maintenance positioning component is located at the front of the mounting plate.

[0007] Furthermore, the tension adjustment assembly includes: a transmission screw, a drive slider, and a connecting rod; the transmission screw is rotatably connected inside the guide rail; the drive slider is slidably connected inside the guide rail, and the drive slider is threadedly connected to the transmission screw; the bottom of the connecting rod is hinged to the front of the drive slider.

[0008] Furthermore, the tension adjustment assembly also includes: a tension sprocket, a first connecting member, a fixing block, a second connecting member, and a tension spring; the tension sprocket is hinged to the rear of the top of the connecting rod; the first connecting member is fixedly connected to the top of the connecting rod; the fixing block is fixedly connected to the front of the mounting plate; the second connecting member is hinged to the front of the fixing block; and the upper and lower ends of the tension spring are fixedly connected to the first connecting member and the second connecting member, respectively.

[0009] Furthermore, the tension adjustment assembly also includes: a fixing plate, fixing bolts, and a threaded limiting rod; the fixing plate is fixedly connected to the front of the mounting plate; two fixing bolts are provided, and the two fixing bolts are respectively fixedly connected to the upper and lower sides of the fixing plate; the threaded limiting rod is threadedly connected inside the two fixing bolts, and the bottom of the threaded limiting rod contacts the top of the connecting rod.

[0010] Furthermore, the maintenance positioning component includes: a positioning box, a first sliding member, and a tension spring; the positioning box is fixedly connected to the rear of the connecting rod; the front end of the first sliding member is slidably connected inside the positioning box; the rear end of the tension spring is fixedly connected to the front of the first sliding member, and the front end of the tension spring is fixedly connected inside the positioning box.

[0011] Furthermore, the maintenance positioning component also includes: a second sliding member, an operation key, a positioning post, and a positioning spring; the second sliding member is slidably connected inside the first sliding member; the operation key is fixedly connected below the second sliding member; the positioning post is fixedly connected below the second sliding member; the bottom of the positioning spring is fixedly connected above the second sliding member, and the top of the positioning spring is fixedly connected inside the first sliding member.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] First, by setting up a tension adjustment component, not only can the chain length change during long-term operation be automatically compensated by the tension spring to ensure transmission stability, but the swing range of the tension sprocket can also be manually adjusted and limited by driving the slider to move left and right and the threaded limit rod to move up and down, further improving the adjustability of the chain tension and ensuring the smooth operation of the dial rod.

[0014] Secondly, when it is necessary to repair or replace the chain or tension spring, the position of the tension sprocket can be temporarily locked through the maintenance positioning component. This design eliminates the need to repeatedly calibrate the meshing position of the tension sprocket and the chain, greatly reducing the difficulty of reinstalling a new chain or tension spring later, reducing maintenance time, and ensuring that the instant noodle production line can quickly resume continuous and stable operation after maintenance.

[0015] This invention utilizes a tension spring to automatically compensate for changes in chain length during operation, ensuring smooth transmission. Simultaneously, it employs the movement of a drive slider and the adjustment of a threaded limit rod to manually control and limit the swing range of the tension sprocket. Furthermore, a maintenance positioning component allows for temporary locking of the tension sprocket position during chain and tension spring repairs, eliminating the need for repeated calibration of the meshing position. This significantly reduces installation difficulty and maintenance time, providing stable and efficient noodle cake conveying support for instant noodle production lines. It effectively reduces production interruptions and lowers equipment maintenance costs, offering reliable technical support for improving production continuity and optimizing overall production efficiency in the instant noodle processing industry, and facilitating long-term, stable, and large-scale operation of the production line.

Detailed Implementation

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 7 As shown:

[0028] This utility model provides a face toggle lever transmission system with automatic tension adjustment, including a mounting plate 1, fixed sprockets 101, chain boxes 2, chains 3, face toggle levers 301, guide rails 4, fixed boxes 16, positioning holes 1601, and tension adjustment components. Three fixed sprockets 101 are provided, each rotatably connected to the front of the mounting plate 1. Two chain boxes 2 are provided, each fixedly connected to the front of the mounting plate 1. The chain 3 meshes with the outside of the three fixed sprockets 101 and passes through the interior of the two chain boxes 2. The face toggle lever 301 is fixedly connected to the rear of the chain 3. The guide rail 4 is fixedly connected to the front of the mounting plate 1. The fixed box 16 is fixedly connected to the front of the mounting plate 1, and a square slot is provided at the front end of the fixed box 16. The positioning hole 1601 is located at the front end of the fixed box 16. The tension adjustment components are located at the front of the mounting plate 1.

[0029] The tension adjustment assembly includes: a transmission screw 5, a drive slider 6, and a connecting rod 7; the transmission screw 5 is rotatably connected inside the guide rail 4; the drive slider 6 is slidably connected inside the guide rail 4, and the drive slider 6 is threadedly connected to the transmission screw 5; the bottom of the connecting rod 7 is hinged to the front of the drive slider 6.

[0030] The tension adjustment assembly also includes: a tension sprocket 701, a first connector 702, a fixing block 8, a second connector 9, and a tension spring 10; the tension sprocket 701 is hinged to the rear of the top of the connecting rod 7; the first connector 702 is fixedly connected to the top of the connecting rod 7; the fixing block 8 is fixedly connected to the front of the mounting plate 1; the second connector 9 is hinged to the front of the fixing block 8; and the upper and lower ends of the tension spring 10 are fixedly connected to the first connector 702 and the second connector 9, respectively.

[0031] The tension adjustment assembly also includes: a fixing plate 11, fixing bolts 1101, and a threaded limiting rod 12; the fixing plate 11 is fixedly connected to the front of the mounting plate 1; two fixing bolts 1101 are provided, and the two fixing bolts 1101 are respectively fixedly connected to the upper and lower sides of the fixing plate 11; the threaded limiting rod 12 is threadedly connected inside the two fixing bolts 1101, and the bottom of the threaded limiting rod 12 contacts the top of the connecting rod 7.

[0032] The specific usage and function of this embodiment are as follows: During use, when the chain 3 is slack, the preload of the tension spring 10 pushes the tension sprocket 701 to move downwards and to the right around the hinge point between the connecting rod 7 and the drive slider 6, restoring the chain 3 to a suitable tension and preventing tooth skipping and transmission slippage. When the chain 3 is too tight, it pushes the tension sprocket 701 and the tension spring 10 in the opposite direction, causing the tension sprocket 701 to move upwards and to the left, preventing excessive tension from aggravating wear or damaging the transmission components. In short, the "elastic floating" of the tension spring 10 allows the tension sprocket 701 to automatically adjust its position, continuously compensating for changes in the chain 3's length, ensuring a consistently smooth and reliable transmission. Manually rotating the left end of the transmission screw 5 can drive the drive slider 6 to move left and right, thereby changing the left and right position of the bottom of the connecting rod 7. This causes the pivot position of the tension sprocket 701 to change, allowing manual adjustment of the initial tension of the tension sprocket 701 on the chain 3. The bottom of the threaded limit rod 12 contacts the top of the connecting rod 7, limiting the maximum swing range of the connecting rod 7 to the upper left, preventing the chain 3 from being too tight and thus aggravating wear or damaging the transmission components. At the same time, the threaded limit rod 12 is threadedly connected to two fixing bolts 1101, making it convenient to rotate the threaded limit rod 12 to adjust the bottom height, and more accurately adjust the maximum swing range of the tension sprocket 701 to the upper left.

[0033] Example 2:

[0034] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 7 As shown, it also includes a maintenance positioning component, which is located in front of the mounting plate 1.

[0035] The maintenance positioning component includes: a positioning box 13, a first sliding member 14, and a tension spring 1401; the positioning box 13 is fixedly connected to the rear of the connecting rod 7; the front end of the first sliding member 14 is slidably connected inside the positioning box 13; the rear end of the tension spring 1401 is fixedly connected to the front of the first sliding member 14, and the front end of the tension spring 1401 is fixedly connected inside the positioning box 13.

[0036] The maintenance positioning component also includes: a second sliding member 15, an operation key 1501, a positioning post 1502, and a positioning spring 1503; the second sliding member 15 is slidably connected inside the first sliding member 14; the operation key 1501 is fixedly connected below the second sliding member 15; the positioning post 1502 is fixedly connected below the second sliding member 15; the bottom of the positioning spring 1503 is fixedly connected above the second sliding member 15, and the top of the positioning spring 1503 is fixedly connected inside the first sliding member 14.

[0037] The specific usage and function of this embodiment: When the chain 3 or tension spring 10 needs to be repaired or replaced after a long period of use, firstly, manually rotate the left end of the transmission screw 5 to drive the drive slider 6 to move to the initial position. Then, manually swing the limiting connecting rod 7 to align the positioning box 13 with the fixed box 16. After that, press the operation key 1501 upward to drive the second sliding member 15 and the positioning post 1502 to retract towards the inside of the first sliding member 14. Then, push the first sliding member 14 forward to insert it into the square slot in the fixed box 16. Release the operation key 1501. Under the rebound action of the positioning spring 1503, the positioning post 1502 moves downward to insert into the positioning hole 1601, so that the positioning box 13 is temporarily locked in front of the fixed box 16. In this way, when the chain 3 or tension spring 10 is removed and replaced, the position of the tension sprocket 701 will remain unchanged, which is convenient for subsequent reinstallation of the new chain 3 or tension spring 10.
