Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a raw material pretreatment device for food processing. Background Art

[0002] Food processing refers to the grain milling, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as processing activities of vegetables, fruits and nuts that directly use agricultural, forestry, animal husbandry and fishery products as raw materials. It is a type of agricultural product processing industry in a broad sense. During food processing, its raw materials need to be pretreated. Screening is required during the pretreatment process to separate the raw materials according to the size and quality of the cones so that the size of the raw materials after screening is approximately equal, so a pretreatment device is needed.

[0003] After searching, the Chinese patent application number 201921435609.6 discloses a raw material pretreatment device for food processing, including a pretreatment box, a feed pipe is connected to the center of the top of the pretreatment box, and limiting mechanisms are provided on both sides of the top of the inner cavity of the pretreatment box. The bottom of the limiting mechanism is fixedly connected to a screening mechanism, the right side of the pretreatment box is fixedly connected to a transmission box, and the right side of the inner cavity of the transmission box is fixedly connected to a U-shaped frame;

[0004] Although the above patent has the advantages of good screening effect, simple operation, easy use by users, saving time and manpower, and improving screening efficiency, it still has the following shortcomings during use: in the process of fine screening of raw materials using a screening mechanism, larger particles of material will be retained inside the screening mechanism, so that the equipment needs to be suspended, and then these particles that do not meet the size requirements are manually cleaned out before the screening operation can be resumed. This series of operating steps is relatively complicated, which is not conducive to improving production efficiency and achieving continuity in the screening of raw materials.

[0005] Therefore, a food processing raw material pretreatment device is urgently needed to solve the above problems. Utility Model Content

[0025] like Figure 1-6 As shown, as a preferred embodiment, on the basis of the above method, further, the driving assembly includes a first crank 110 rotatably connected to the side wall of the screening frame 101, and the first crank 110 is symmetrically arranged in two groups about the central axis of the screening frame 101. The side wall of the baffle 105 is fixedly connected with an arc ring 111, and the first crank 110 cooperates with the arc ring 111. The inner wall of the slide groove 104 is fixedly connected with a spring 112, and the end of the spring 112 away from the slide groove 104 is also fixedly connected to the baffle 105. When the first crank 110 is away from the arc ring 111 under the action of the spring 112, the baffle 105 can be reset under the action of the spring 112, which is more convenient to use. The arc plate 111 and the output end of the first crank 110 are made of soft material, which can increase their service life.

[0026] like Figure 1-5As shown, as a preferred embodiment, on the basis of the above method, further, the side wall of the screening frame 101 is fixedly connected to the support plate 120, and the side wall of the support plate 120 is fixedly connected to the driving motor 121, and the output end of the driving motor 121 is fixedly connected to the rotating rod 122, and the outer wall of the rotating rod 122 is fixedly connected to the first bevel gear 123, and the side wall of the screening frame 101 is rotatably connected to the driving rod 124, and the driving rod 124 is symmetrically arranged with two groups about the central axis of the screening frame 101, and the side wall of the driving rod 124 is fixedly connected to the second bevel gear 125, and the first bevel gear 123 is meshed with the second bevel gear 125. The outer wall of the driving rod 124 is connected to the first crank 110 through a pulley group 126, and the driving rod 124 can be driven to rotate under the action of the first bevel gear 123 and the second bevel gear 125, which is beneficial to improve the synchronization during screening.

[0027] like Figure 1-3 As shown, as a preferred embodiment, on the basis of the above method, a reciprocating groove 130 is further provided on the side wall of the screening frame 101, and a reciprocating ring 131 is slidably connected to the side wall of the screening frame 101 through the reciprocating groove 130, and the reciprocating ring 131 is connected to the screening plate 103 through the reciprocating groove 130, and the side wall of the rotating rod 122 is fixedly connected to the second crank 132, and the output end of the second crank 132 is slidably connected to the reciprocating ring 131. By setting the second crank 132, the reciprocating ring 131 can be driven to perform reciprocating motion, which has stronger applicability.

[0028] like Figure 1-2 As shown, as a preferred embodiment, on the basis of the above method, further, a discharge chute 133 is opened on the top wall of the screening frame 101, a discharge hopper 134 is fixedly connected to the top wall of the discharge chute 133, and a partition 135 is fixedly connected to the side wall of the fixed frame 100.

[0029] Specifically, when the raw material pretreatment device for food processing is used: first, the driving motor 121 is started to drive the rotating rod 122 to rotate, and the second crank 132 is driven to rotate through the rotating rod 122. When the second crank 132 rotates, the reciprocating ring 131 is driven to slide in the reciprocating groove 130, and the reciprocating ring 131 drives the screening plate 103 to reciprocate left and right in the screening frame 101. The screening plate 103 is supported by the support rod 102, and then the raw materials are poured into the screening frame 101 through the lower hopper 134. The screening plate 103 reciprocates, thereby realizing the screening of the raw materials. At the same time, when the rotating rod 122 rotates, it also synchronously drives the first bevel gear 123 to rotate The second bevel gear 125 is driven to rotate by the first bevel gear 123. When the second bevel gear 125 rotates, the driving rods 124 on both sides are driven to rotate at the same time. The driving rods 124 drive the first crank 110 to rotate under the action of the pulley group 126. When the first crank 110 contacts the arc ring 111, the baffle 105 is lifted, so that the baffle 105 is away from the screening plate 103, and the large particles of raw materials on the screening plate 103 fall to the ground. When the first crank 110 is away from the arc ring 111, the baffle 105 is reset under the action of the spring 112, and the action of the partition 135 can prevent the screened raw materials from being mixed together again, thereby improving the convenience of use and facilitating continuous screening operations.
