Description

Technical Field

[0001] The utility model belongs to the field of fresh corn processing equipment, and particularly relates to a corn positioning sleeve device for a corn peeling machine. Background Art

[0002] Fresh corn, also known as fruit corn, refers to young, tender corn with a unique flavor and quality. Since the edible part of fresh corn consists of immature, tender kernels, it undergoes vigorous respiration and metabolism after harvest, rapidly converting sugars and easily losing water and deteriorating. This makes long-term storage difficult. For long-term storage or year-round supply, it must be quickly frozen or vacuum-packed. This requires rapid processing of the fresh corn after harvest, removing the root, tip, skin, and silk before sealing or quick freezing.

[0003] There are many devices available that can process fresh corn, such as a fresh corn processing device with publication number CN219679711U and a root positioning structure with publication number CN219819890U, both of which are devices for processing fresh corn.

[0004] A positioning sleeve structure is required in these devices to achieve the positioning of the corn roots. In the prior art, the positioning sleeves are fixed to the mounting plate by bolts. However, in the actual processing process, positioning sleeves of different sizes may need to be replaced according to the size of the corn. In this way, all bolts need to be removed before the positioning sleeves can be removed, which makes the replacement inefficient. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a corn positioning sleeve device for a corn peeling machine, which can realize the rapid replacement of the positioning sleeve.

[0006] The technical solution adopted in this utility model is:

[0007] A corn positioning sleeve device for a corn peeling machine includes a base and a positioning sleeve arranged on the base, wherein an internal thread sleeve is provided on the base, an external thread sleeve adapted to the internal thread sleeve is provided at the bottom of the positioning sleeve, and a backflow prevention device is provided between the base and the positioning sleeve.

[0008] Furthermore, the anti-return device includes a limiting block provided on the outer side wall of the positioning sleeve and an elastic protrusion provided on the base for cooperating with the limiting block.

[0009] Furthermore, a groove is provided on the outer ring of the base, one end of the elastic protrusion is located on the side wall of the groove, and the other end protrudes upward to cooperate with the limit block.

[0010] Furthermore, a handle portion is provided at the end of the elastic protrusion.

[0011] Furthermore, a plurality of limiting blocks are evenly arranged on the outer side wall of the positioning sleeve.

[0012] Furthermore, the base has an annular outer wall, the groove is provided on the annular outer wall, and the limiting block cooperates with the top surface of the annular outer wall.

[0013] Furthermore, a matching groove is provided at the bottom end of the limiting block, and the matching groove matches with the annular outer side wall.

[0014] The positive effects of this utility model are:

[0015] The positioning sleeve of this utility model is connected to the internal threaded sleeve on the base via its own external threaded sleeve. When the positioning sleeve needs to be replaced, it can be removed by simply twisting the positioning sleeve, making it very convenient to disassemble and replace. At the same time, there is a backstop device between the base and the positioning sleeve, which can effectively prevent the positioning sleeve from loosening and preventing it from shifting or falling during use.

[0019] As attached Figure 1-3 As shown, the utility model discloses a corn positioning sleeve device for a corn peeling machine, comprising a base 1 and a positioning sleeve 2. The base 1 is provided with a plurality of through holes 9, which are used to fix the base 1 on the corn peeling machine. An internal threaded sleeve 3 is provided at the center position of the base 1, and an external threaded sleeve 7 is provided at the bottom center position of the positioning sleeve 2. The internal threaded sleeve 3 cooperates with the external threaded sleeve 7 so that the positioning sleeve 2 can be installed on the base 1. The connection between the base 1 and the positioning sleeve 2 can be achieved through the threaded structure provided by the base 1 and the positioning sleeve 2, without the need for additional bolts or other structures. The installation and disassembly are very convenient, and the size of the positioning sleeve 2 can be easily changed according to actual processing needs.

[0020] The inner side wall of the positioning sleeve 2 is a trumpet-shaped opening for contacting the root of the corn to limit its position.

[0021] As a further improvement, a backflow prevention device is provided between the base 1 and the positioning sleeve 2. Once the internal and external threaded sleeves are in place, the backflow prevention device prevents the positioning sleeve 2 from reversing, thus preventing the positioning sleeve 2 from loosening during use and causing inaccurate positioning. Specifically, the backflow prevention device includes a limit block 6 provided on the outer wall of the positioning sleeve 2 and an elastic protrusion 5 provided on the base 1 for cooperating with the limit block 6. During the installation of the positioning sleeve 2, the elastic protrusion 5 is inactive. Once in place, the elastic protrusion 5 cooperates with the limit block 6 to prevent the positioning sleeve 2 from reversing and falling off.

[0022] The outer ring of the base 1 comprises an annular outer wall with a groove 4 formed therein. One end of an elastic protrusion 5 is connected to the sidewall of the groove 4, while the other end protrudes upward from the top surface of the outer wall. The inclination of the elastic protrusion 5 aligns with the installation rotational direction of the locating sleeve 2. In other words, during installation of the locating sleeve 2, because the inclination of the elastic protrusion 5 aligns with it, when the stop block 6 passes by the elastic protrusion 5, the elastic protrusion 5 is depressed and ineffective. However, when the stop block 6 does not engage the elastic protrusion 5, the elastic protrusion 5 moves upward into the path of the stop block 6. Consequently, when the locating sleeve 2 tends to reverse, the elastic protrusion 5 blocks the movement and prevents the locating sleeve 2 from falling off, achieving a reverse-rotation effect. The end of the elastic protrusion 5 is provided with an outward-facing handle. When the locating sleeve 2 needs to be replaced, the elastic protrusion 5 is pressed downward to clear the path of the stop block 6, allowing the locating sleeve 2 to be removed and replaced.

[0023] Preferably, a number of limit blocks 6 are evenly provided on the outer wall of the positioning sleeve 2. On the one hand, it can have multiple limit positions and can play a anti-return effect at any time. On the other hand, the limit block 6 can also play the role of a reinforcing rib. A matching groove 8 is provided at the lower end of the limit block 6. When the positioning sleeve 2 is installed in place, the matching groove 8 contacts and cooperates with the top surface of the annular outer wall.

[0024] The structure of the utility model realizes the rapid disassembly and installation of the positioning sleeve 2. It is not only convenient to disassemble, but also has an anti-return device. After the installation is completed, it can effectively prevent the positioning sleeve 2 from falling off and shifting, and is safe and reliable to use.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
