Detailed implementation manners

[0051] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the implementation manners and the drawings. Herein, the illustrative implementation manners of the present application and their descriptions are used to explain the present application, but do not limit the present application.

[0052] During the production of prefabricated noodles, the semi-finished products mainly consist of a storage box and frozen bottom soup, and their overall height is relatively low. The finished products, on the other hand, add frozen noodles and toppings on the basis of the semi-finished products, and the height of the finished products is higher than that of the semi-finished products. During the production process of prefabricated noodles, the semi-finished products and the finished products sometimes get mixed. In order to ensure the smooth progress of subsequent processing, these two types of products must be effectively separated. For this reason, technical personnel designed a conveyor sorting device to separate the semi-finished products and the finished products according to the height difference of the products, so as to improve the separation efficiency and accuracy, and further effectively improve the product quality and production efficiency during the production process of prefabricated noodles.

[0053] Refer to Figures 1 to 10 , such as Figure 1As shown in the figure, this embodiment provides a conveying and sorting device for prefabricated noodle production, including: a direct conveyor belt 1, a first sorting conveyor belt 3, a second sorting conveyor belt 4, a blocking and limiting member 2, and an intercepting and diverting rod 7. The direct conveyor belt 1 conveys the products to the sorting position. The first sorting conveyor belt 3 and the second sorting conveyor belt 4 are arranged side by side at the tail of the direct conveyor belt 1 (i.e., the sorting position). The blocking and limiting member 2 is arranged at the tail of the direct conveyor belt 1, and the blocking and limiting member 2 can change the moving direction of the products so as to facilitate the introduction of the products from the direct conveyor belt 1 onto the second sorting conveyor belt 4. One end of the intercepting and diverting rod 7 is fixed by a first height adjusting mechanism 8 arranged on the right side of the second sorting conveyor belt 4, and the other end extends obliquely across the second sorting conveyor belt 4 and then to the first sorting conveyor belt 3. The height of the intercepting and diverting rod 7 can be adjusted by the first height adjusting mechanism 8. The intercepting and diverting rod 7 extends obliquely from the outside of the second sorting conveyor belt 4 to the first sorting conveyor belt 3, so that products with different heights can flow into the first sorting conveyor belt 3 or the second sorting conveyor belt 4 under the restriction of the intercepting and diverting rod 7.

[0054] In the embodiment of the present application, the products are divided into semi-finished products and finished products, and the two have different heights.

[0055] In the embodiment of the present application, first guardrails 31 and second guardrails 32 are oppositely arranged on both sides of the first sorting conveyor belt 3. The first guardrails 31 and the second guardrails 32 are used to enclose the products so that the products can move smoothly on the first sorting conveyor belt 3 without falling. A number of second height adjusting mechanisms 10 are arranged on both the first sorting conveyor belt 3 and the second sorting conveyor belt 4. The second height adjusting mechanisms 10 can adjust the heights of the first guardrails 31 and the second guardrails 32 of the first sorting conveyor belt 3 and the third guardrails 41 and the fourth guardrails 42 of the second sorting conveyor belt 4.

[0056] Preferably, the first sorting conveyor belt 3 is located on the left side of the second sorting conveyor belt 4, and the second guardrails 32 and the fourth guardrails 42 are located between the first guardrails 31 and the third guardrails 41.

[0057] Such as Figure 6 and Figure 7As shown, the first height adjustment mechanism 8 includes: a first bracket 81, a second bracket 84, a handle screw 83, and a fixing buckle 85. The first bracket 81 is fixed to the side of the second sorting conveyor belt 4 by a fixing screw 82 to serve as the core support point of the entire first height adjustment mechanism 8. The second bracket 84 is slidably inserted into the through hole 811 of the first bracket 81 to enable flexible adjustment of the second bracket 84. The through hole 811 penetrates the upper and lower surfaces of the first bracket 81. The handle screw 83 can lock the second bracket 84 to ensure the stability of the second bracket 84 without displacement. The fixing buckle 85 is connected to the second bracket 84. The fixing buckle 85 is used to fix the intercepting rod 71 of the intercepting and diverting rod 7. Through the fastening action of the fixing buckle 85, the intercepting rod 71 is firmly fixed at the required position to effectively perform its duty of intercepting and diverting. The entire structure is convenient to operate.

[0058] As Figure 8 shown, the fixing buckle 85 includes: a U-shaped frame 851, a pair of U-shaped rods 852, and a pair of limit blocks 854. The U-shaped frame 851 is connected to the second bracket 84. A pair of U-shaped rods 852 are symmetrically arranged within the U-shaped frame 851. The limit blocks 854 are elastically arranged within the trapezoidal holes 8521 of the corresponding U-shaped rods 852. This design enables the limit blocks 854 to flexibly abut against the intercepting rod 71. When the intercepting rod 71 needs to be fixed, the limit blocks 854 will use their elastic force to tightly fit against the intercepting rod 71 to ensure that it does not shift or shake. This structural design not only improves the stability of the fixation but also makes the entire fixation process more convenient and efficient.

[0059] Preferably, the fixing buckle 85 further includes a pair of first compression springs 853. The first compression springs 853 are connected between the corresponding limit blocks 854 and the U-shaped frame 851 to enable elastic pressing between the limit blocks 854 and the intercepting rod 71.

[0060] Preferably, both sides of the limit block 854 have inclined surfaces 8541, and the inclined surfaces 8541 are adapted to the trapezoidal holes 8521.

[0061] As Figure 7 shown, a plurality of adjustment holes 841 are provided on the second bracket 84. The handle screw 83 is adapted to the adjustment holes 841. The handle screw 83 is threadedly connected to the first bracket 81 to enable the handle screw 83 to rotate smoothly, and the inner end of the handle screw 83 can press against the inside of the first bracket 81.

[0062] As Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, one end of the intercepting rod 71 is connected to the fixed buckle 85 to fix the intercepting rod 71, and the other end is connected to the second guardrail 32 through a long screw 73. The second guardrail 32 and the fourth guardrail 42 are connected through a connecting sleeve 9 to realize the connection between the intercepting rod 71, the second guardrail 32 and the fourth guardrail 42. By connecting the three, the installation of the intercepting rod 71 can be made more stable and firm.

[0063] Preferably, a threaded hole 711 is provided in the intercepting rod 71, and the long screw 73 is adapted to the threaded hole 711. A support seat 731 is connected to the lower end of the long screw 73, and the support seat 731 presses against the receiving groove 321 provided at the upper end of the second guardrail 32, so that the connection between the intercepting rod 71 and the second guardrail 32 is reliable. The second guardrail 32 is connected to the fourth guardrail 42 through the connecting sleeve 9, so that the intercepting rod 71, the second guardrail 32 and the fourth guardrail 42 are firmly connected to each other.

[0064] Preferably, the connecting sleeve 9 is bent from a soft material, and the bent part is arc-shaped, which can effectively reduce collisions, prevent the product from being broken by impact, and can also effectively connect the second guardrail 32 and the fourth guardrail 42.

[0065] As Figure 10 As shown, the second height adjusting mechanism 10 includes: a first mounting bracket 101, a vertical rod 104, a first handle screw 102, a third bracket 103, a cross bar 105 and a second handle screw 107. The first mounting bracket 101 is mounted on the side of the first sorting conveyor belt 3 / the second sorting conveyor belt 4; the vertical rod 104 is slidably engaged with the first mounting bracket 101 to facilitate adjusting the placement height of the vertical rod 104; the first handle screw 102 is threadedly connected to the first mounting bracket 101, and the inner end of the first handle screw 102 can abut against the side of the vertical rod 104 to lock the vertical rod 104; the third bracket 103 is connected to the upper end of the vertical rod 104; the cross bar 105 is slidably engaged with the third bracket 103 to facilitate adjusting the horizontal placement position of the cross bar 105. A connecting seat 106 is connected to the cross bar 105, and the connecting seat 106 can be connected to the first guardrail 31 / the second guardrail 32 / the third guardrail 41 / the fourth guardrail 42; the second handle screw 107 is threadedly connected to the third bracket 103, and the lower end of the second handle screw 107 can abut against the cross bar 105 to lock the cross bar 105.

[0066] Preferably, the connecting seat 106 is preferably made of plastic. The connecting seat 106 has a C-shaped cavity to hold the first guardrail 31 / second guardrail 32 / third guardrail 41 / fourth guardrail 42 therein, achieving connection with the second height adjustment mechanism 10. When in use, loosen the first handle screw 102, and the height of the vertical rod 104 can be adjusted, thereby adjusting the height of the first guardrail 31 / second guardrail 32 / third guardrail 41 / fourth guardrail 42. Loosen the second handle screw 107, and the horizontal distance of the cross rod 105 can be adjusted, so that the distance between the first guardrail 31 and the second guardrail 32 or the distance between the third guardrail 41 and the fourth guardrail 42 can be adjusted to adapt to the movement of products with different diameters. By adjusting the height of the first guardrail 31 / second guardrail 32 / third guardrail 41 / fourth guardrail 42, the product can be protected according to the actual situation during specific use, ensuring the safety of movement.

[0067] As Figure 2 shown, the blocking and limiting member 2 includes a pair of vertical rods 21 and a limiting plate 22. The pair of vertical rods 21 are arranged at intervals on the direct conveyor belt 1, and the limiting plate 22 is connected between the pair of vertical rods 21. The limiting plate 22 is an arc-shaped structure, which not only reduces the impact on the product but also enables the product to move smoothly towards the second sorting conveyor belt 4. A first protective pad 23 is provided on the limiting plate 22, and the first protective pad 23 can protect the product and reduce rigid collisions.

[0068] As Figure 9 shown, a second anti-collision pad 72 is sleeved on the intercepting rod 71. The second anti-collision pad 72 can protect the product again and reduce rigid collisions, and the second anti-collision pad 72 is wrapped around the outer periphery of the intercepting rod 71, which is convenient to replace.

[0069] Working principle: Semi-finished products and finished products with different heights flow on the direct conveyor belt 1 and flow to the blocking and limiting member 2. The limiting plate 22 limits the position, causing the movement direction of the product to change, and then the product moves onto the second sorting conveyor belt 4. The second sorting conveyor belt 4 drives the product to continue moving. Under the action of the intercepting rod 71, the products lower than the height of the intercepting rod 71 (i.e., semi-finished products) continue to move forward along the second sorting conveyor belt 4, while the products higher than the height of the intercepting rod 71 (finished products) are carried by the intercepting rod 71 and move towards the first sorting conveyor belt 3, and finally continue to move forward on the first sorting conveyor belt 3.

[0070] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the embodiments of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
