Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of raw material conveying, in particular to a raw material conveying equipment for fruit can processing. BACKGROUND

[0002] In the production process of fruit cans, a large amount of conveying equipment is used. At present, most fruit can production lines use belt and scraper lifting conveying equipment. The belt conveying equipment is only used for horizontal or small-angle conveying. The scraper lifting equipment, that is, the scraper structure is added to the chain plate or belt, so that it can realize lifting to a certain height and meet the technical requirements of fruit can processing. When lifting to a certain height, the space formed by the distance between the scrapers is limited, the conveying capacity is limited, and part of the fruits will slide into the space formed by the scrapers below, which greatly reduces the conveying efficiency.

[0003] Therefore, the Chinese patent with the publication number "CN211544913U" discloses a fruit conveying and lifting equipment. The main structure includes a circular arc-shaped conveying shell. A driving shaft is arranged in the conveying shell. The two ends of the driving shaft are fixed through a bearing seat. The driving shaft is drivingly connected with a driving device. A spiral blade is arranged on the driving shaft. The spiral blade is spirally wound on the driving shaft. A rotating gap is formed between the outer edge of the spiral blade and the conveying shell. The fruit conveying and lifting equipment is provided with a driving shaft in the circular arc-shaped conveying shell. The spiral blade is distributed on the driving shaft in the axial direction. The fruit falls into one end of the conveying shell and is gradually lifted to a set height after being pushed by the spiral blade. The fruit will not slide into the area below under the pushing of the spiral blade. The conveying capacity requirement can be met, the efficiency is high, and the fruit will not be damaged. The fruit conveying and lifting equipment is suitable for conveying and lifting of fruits at a large angle.

[0004] The fruit conveying and lifting equipment uses a feeding bin opened on one side of the equipment to feed raw materials. During the feeding process, fruits of different sizes are guided to the vicinity of the spiral blade. Some larger fruits (the size of the fruit is greater than the pitch of the spiral blade) will be damaged by being cut by the spiral blade, resulting in waste of raw materials. In addition, the feeding efficiency is reduced due to the feeding port opened on one side, which finally leads to a decrease in the conveying efficiency. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a raw material conveying equipment for fruit can processing, which can feed raw materials from the periphery of the spiral blade, thereby increasing the raw material feeding space and improving the raw material conveying efficiency. In addition, the device can select a suitable fence type screening mechanism according to the actual needs, thereby screening fruit raw materials of the required size to ensure the normal conveying of fruits of the appropriate size and solve the above technical problems.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 A raw material conveying device for fruit canning includes a bottom support frame 1 with a first fixing ring 2 installed on the top and a motor mounting base 3 with a drive motor 4 installed in the center. The bottom support frame 1 and the motor mounting base 3 are fixedly installed on the ground of the working area, and then components for collecting raw materials are set around the discharge hole of the upper hollow conveying pipe 51.

[0021] To achieve the upward conveying function of raw materials, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 and Figure 4 A spiral pipe conveying mechanism 5 needs to be installed. Its structure includes an upper hollow conveying pipe 51 and a lower hollow conveying pipe 52 for guiding and conveying fruit raw materials, a funnel-shaped feeding trough 54 set between the upper hollow conveying pipe 51 and the lower hollow conveying pipe 52 for feeding raw materials, and a spiral blade 510 installed at the axis of the upper hollow conveying pipe 51 and the lower hollow conveying pipe 52 for driving the raw materials to move upward. The raw materials are fed into the funnel-shaped feeding trough 54. Under the action of gravity, the fruit raw materials that meet the requirements will roll around the spiral blade 510. The drive motor 4 is turned on, and its rotor will drive the spiral blade 510 to rotate in a direction. Driven by the spiral blade 510, the raw materials will move upward continuously and finally be output through the discharge port of the upper hollow conveying pipe 51, thereby realizing the upward conveying function of the raw materials.

[0022] For details regarding the specific structure of the spiral pipeline conveying mechanism 5, please refer to [link / reference]. Figure 3 and Figure 4 It also includes an upper conveying cavity 58 located inside the upper hollow conveying pipe 51 and open at both ends; a lower conveying cavity 53 with an open top located inside the lower hollow conveying pipe 52; a first shaft hole 55 connecting the lower hollow conveying pipe 52 to the lower conveying cavity 53 located at the bottom end of the lower hollow conveying pipe 52; a rotatable longitudinal shaft 59 mounted in the first shaft hole 55 via a bearing in the lower hollow conveying pipe 52; an outwardly expanding trumpet-shaped feeding trough 54 located at the top end of the lower hollow conveying pipe 52; and an integrally formed structure at the bottom of the upper hollow conveying pipe 51. The first contact ring 56 has an annular protrusion 57 integrally formed at the center of its bottom surface. Rotatable spiral blades 510 are installed at the center of the lower conveying cavity 53 and the upper conveying cavity 58. The bottom end of the longitudinal rotating shaft 59 is fixedly connected to the rotor end of the drive motor 4. After the drive motor 4 is started, the rotation of the spiral blades 510 causes the surrounding raw materials to move upwards. The distance between the top end of the lower conveying cavity 53 and the bottom end of the upper conveying cavity 58 is less than the depth of the funnel-shaped feeding trough 54. To achieve screening of raw materials of different sizes, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 5 A fence-type screening mechanism 6 needs to be set up. Its structure includes a second contact ring 61 that can be locked at the bottom of the lower hollow conveying pipe 52, a third contact ring 62 that can abut against the axis of the upper hollow conveying pipe 51, and a partition rod 64 installed between the second and third contact rings 61 and capable of screening the raw materials by size. Different sizes of fence-type screening mechanisms 6 are selected according to actual needs. The screening size of the fence-type screening mechanism 6 is the horizontal distance between two adjacent partition rods 64. Using this principle, fruits smaller than the screening size can pass through the gap between the two partition rods 64 normally, while fruits larger than the screening size will be blocked to prevent them from being conveyed, thereby realizing the screening of raw materials of different sizes.

[0023] For details regarding the specific structure of the fence-type screening mechanism 6, please refer to [link / reference]. Figure 5It also includes an annular groove 63 recessed on the upper surface of the second contact ring 61. The shape and size of the annular groove 63 are adapted to the annular protrusion structure 57. A conical contact ring 65 is provided at the bottom of the third contact ring 62. Multiple annular array partition rods 64 are fixedly installed between the second contact ring 61 and the third contact ring 62. The shape of the bottom of the conical contact ring 65 is adapted to the bottom structure of the trumpet-shaped feeding trough 54. The distance between two adjacent partition rods 64 is less than the height of the partition rod 64 and meets the rated size for conveying raw materials.

[0024] To achieve elastic support for the upper hollow conveying pipe 51, thereby reducing the load on the fence-type screening mechanism 6, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 6 and Figure 7 An elastic support mechanism 7 needs to be set up. Its structure includes a second fixing ring 71 fixedly installed on the outer periphery of the top of the lower hollow conveying pipe 52, a third fixing ring 72 fixedly installed on the outer periphery of the middle of the upper hollow conveying pipe 51, and a helical spring 78 that provides elastic support for the second fixing ring 71 and the third fixing ring 72. Since the cross-sectional shape of the rod through hole 75 is consistent with the cross-sectional shape of the longitudinal limiting rod 76, both of which are polygonal structures, and the cross-sectional dimensions of the rod through hole 75 match the cross-sectional dimensions of the longitudinal limiting rod 76, it can limit the movement direction of the upper hollow conveying pipe 51 to axial movement to prevent deviation. The helical spring 78, which is in a compressed state, will transmit an upward elastic force to the upper hollow conveying pipe 51, thereby reducing the load on the fence-type screening mechanism 6.

[0025] For details regarding the specific structure of the elastic support mechanism 7, please refer to [link / reference]. Figure 6 and Figure 7 It also includes a lower limiting plate 73 integrally disposed around the second fixing ring 71 and a middle limiting plate 74 integrally disposed around the third fixing ring 72. The center of the middle limiting plate 74 is provided with a rod through hole 75 with open ends. A longitudinal limiting rod 76 passing through the rod through hole 75 is fixedly installed on the upper surface of the lower limiting plate 73. A coil spring 78 in a compressed state is placed around the rod body located between the lower limiting plate 73 and the middle limiting plate 74. An upper limiting plate 77 is fixedly installed at the top of the longitudinal limiting rod 76. The cross-sectional shape of the rod through hole 75 is consistent with the cross-sectional shape of the longitudinal limiting rod 76, both being polygonal structures, and the structural dimensions of the cross-section of the rod through hole 75 match the cross-section of the longitudinal limiting rod 76.

[0026] In use, the bottom support frame 1 and the motor mounting base 3 are fixedly installed on the ground of the working area. Then, a raw material collection component is set around the discharge hole of the upper hollow conveying pipe 51. The raw material is fed in through the funnel-shaped feeding trough 54. Under the action of gravity, the fruit raw materials that meet the requirements will roll around the spiral blades 510. The drive motor 4 is turned on, and its rotor will drive the spiral blades 510 to rotate in a direction. Driven by the spiral blades 510, the raw material will move upward continuously and finally be output through the discharge port of the upper hollow conveying pipe 51. Different sizes of fence-type screening mechanisms 6 are selected according to actual needs. The screening size of the fence-type screening mechanism 6 is the horizontal distance between two adjacent partition rods 64. Using this principle, fruits smaller than the screening size can pass through the gap between the two partition rods 64 normally, while fruits larger than the screening size will be blocked to prevent them from being conveyed, thereby realizing the screening of raw materials of different sizes.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
