Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and more specifically, to a slicing machine integrating a speed reduction drive unit, a tabletop, and speed reduction drive. Background Art

[0002] Traditional fully automatic tabletop (meat) slicing machines mostly adopt a structural form in which the slicing knife rotates and the meat-carrying table reciprocates separately, and many transmission components cannot be installed inside the tabletop, so a bottom frame is added below. The structure is complex, the overall machine is tall, and the manufacturing cost is also high. There are also those that use a single motor to drive the slicing knife through a gear pair, then extend the transmission chain through a detour outside the tabletop, and then transmit it back to the speed reducer inside the tabletop to drive the meat-carrying table to reciprocate. Similarly, the structure is complex, the volume is large, and the manufacturing cost is high. With the development of technology and the continuous update of design concepts, it is the expectation of the market to timely introduce a fully automatic slicing machine with a compact structure, small size, and higher cost performance.

Although this application can relatively reduce the height of the entire slicing machine to a certain extent, the overall height of the slicing machine is still relatively high and needs further improvement.

[0043] To further understand the content of the present invention, the present invention will be described in detail in combination with the drawings and embodiments.

[0044] Embodiment 1

[0045] A speed reduction transmission unit of this embodiment is combined with Figure 1 . Figure 2 and Figure 3 , and includes a casting box body 104 integrally connected to the inner wall of the table top 101. Through casting technology, the casting box body 104 and the inner wall of the table top 101 are formed into a whole, and a mutually meshing worm wheel 112 and a worm 121 are arranged inside the casting box body 104. The worm wheel 112 and the worm 121 adopt left-handed rotation to adapt to the slow cutting and fast retracting of the reciprocating motion and match the rotation direction of the blade; the worm wheel 112 is fixedly installed on a crank group welded part 110 through a first flat key 111, and the crank group welded part 110 is perpendicular to the inner wall of the table top 101. The crank group welded part 110 is used to drive the connecting rod assembly 141 to move. The worm 121 is perpendicular to the crank group welded part 110, and the worm 121 is driven by a motor 131, thereby forming a speed reduction transmission unit. By driving the worm 121 to rotate through the motor 131, under the meshing action of the teeth, the worm wheel 112 rotates, so that the crank group welded part 110 rotates accordingly, and the movement of the connecting rod assembly 141 is controlled.

[0046] It should be noted that the crank group welded part 110 of this embodiment is an integral body welded by a worm wheel output shaft and a crank, thereby further reducing the number of parts inside the table top 101, reducing the volume of the entire speed reduction transmission unit, improving the integration degree and reducing the production cost at the same time.

[0047] Combined with Figure 2 and Figure 3, the lower end of the casting box body 104 in this embodiment is sealed by a box cover 107, and a bearing concave platform is provided on one end surface of the box cover 107 facing the inner wall of the table surface 101 for installing the second bearing 109; and a welding part mounting hole 105 is provided on the inner wall of the table surface 101 for installing the first bearing 108 and the crank group welding part 110. The first bearing 108 and the second bearing 109 are sleeved on the crank group welding part 110, and one end of the crank group welding part 110 extends out of the box cover 107.

[0048] A worm mounting hole 106 is provided on the side wall of the casting box body 104, and a fourth bearing 123 is installed in the worm mounting hole 106; the worm 121 passes through the worm mounting hole 106 and is connected to the corresponding side wall of the casting box body 104, and a third bearing 122 is installed on the side wall of the casting box body 104. The third bearing 122 and the fourth bearing 123 are sleeved on the worm 121.

By providing the first skeleton oil seal 113 and the second skeleton oil seal 125, on the one hand, the speed reduction transmission unit can be sealed, and on the other hand, the lubricating grease can be effectively prevented from overflowing, thereby ensuring the stability of rotation.

[0050] In addition, the box cover 107 is fixedly installed on the casting box body 104 by a positioning pin or / and fixing screws. Preferably, in this embodiment, the box cover 107 is fixed on the casting box body 104 by the combined action of the positioning pin and the fixing screws.

[0051] It should be noted that a through hole is provided on the side wall of the table surface 101 in this embodiment, and the through hole can be filled with a plug, such as Figure 1As shown, the through hole in this embodiment is directly opposite to the worm mounting hole 106. The purpose of designing this through hole is to facilitate the assembly of the worm 121. Specifically, first, install the first bearing 108 into the welded part mounting hole 105, and then install the second bearing 109, the first skeleton oil seal 113, the crank group welded part 110, the first flat key 111, and the worm gear 112 on the cover 107. At this time, the third bearing 122 can be installed to facilitate the installation of the worm 121. Then, apply sealant to the joint surface of the cover 107 and install it together with parts such as the worm gear 112 onto the table surface 101 at the same time. Align the positioning pin holes of the cover 107 and the table surface 101, install the positioning pins and screw in the fixing screws. While rotating the crank group welded part 110 to check the assembly situation, install the worm 121 through the through hole on the table surface 101 for installing the plug cover. During this process, the worm 121 needs to be rotated appropriately. After the front end of the worm 121 enters the third bearing 122 in place, install the fourth bearing 123, the worm end cover 124, and the second skeleton oil seal 125, and finally install the plug cover to complete the assembly of the speed reduction transmission unit.
