Description

Technical Field

[0001] This utility model relates to the field of fish ball processing and production technology, and in particular to a height adjustment device for the stirring rod of a fish ball machine. Background Technology

[0002] Existing fish ball forming machines require a stirring rod to be lowered into the meat bucket after the minced meat is poured in. This stirs the minced meat and helps it to form fish balls. After use, the stirring rod needs to be moved back up to detach from the meat bucket. However, the following problems exist in the actual retraction process: Existing fish ball forming machines use a rotating sleeve connected to the stirring rod to move it up and down. An adjusting screw extending from the upper part of the machine housing is fixed to this sleeve. Rotating the rotating sleeve, which is threaded onto the adjusting screw above the split machine housing, moves the adjusting screw up and down along a spiral direction, causing the stirring rod to move up and down with it. However, this causes the upper part of the adjusting screw to continuously rise during the upward retraction of the stirring rod, increasing its length extending above the machine housing. In a factory processing environment, this can easily lead to the adjusting screw coming into contact with electrical wires or other parts during its ascent, creating a safety hazard. Furthermore, the adjusting screw extending above the split machine housing increases the overall height of the device, making it prone to collisions during transport. Utility Model Content

[0003] To address the aforementioned problems, the present invention aims to provide a height adjustment device for the stirring rod of a fish ball machine, which solves the problem that the adjusting screw extends above the machine casing when the stirring rod of the existing fish ball forming machine retracts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A height adjustment device for a stirring rod of a fish ball machine is provided on the machine casing and detachably connected to a meat paste stirring rod on the fish ball machine. The device includes a split-type machine casing that is movably sleeved above the meat paste stirring rod and detachably connected to the front side of the fish ball machine by screws; a cover plate that is threadedly connected to the lower end of the split-type machine casing; a retracting screw that is rotatably provided in the split-type machine casing; a retracting assembly that is provided in the split-type machine casing and used to drive the upper part of the meat paste stirring rod sleeved below the retracting screw; a retracting control assembly that is provided above the split-type machine casing and used to drive the retracting screw to rotate; and a stirring control assembly that is provided in the middle of the split-type machine casing and used to drive the meat paste stirring rod to rotate.

[0006] The meat paste stirring rod is provided with a rod retraction groove along the vertical height direction of the split-type casing.

[0007] The retraction assembly includes a pair of sliding tracks on opposite sides of the inner wall of the split housing along the vertical height direction; a movable sleeve movably sleeved at the lower part of the retraction screw along the vertical height direction of the split housing; a height adjustment sleeve detachably connected to the movable sleeve by screws and threadedly connected to the retraction screw; a pair of limiting members fixed on both sides of the outer wall of the movable sleeve and respectively embedded in the corresponding sliding tracks; a first rotary bearing located between the lower part of the inner wall of the height adjustment sleeve and the outer wall of the meat paste stirring rod; and a nut sleeve threadedly connected to the upper end of the meat paste stirring rod.

[0008] More preferably, the tool retraction control assembly includes a turbine fixedly sleeved on the upper end of the tool retraction screw, a worm gear rotatably disposed in the upper part of the split housing and meshing with the turbine, and a drive motor fixedly disposed on the rear side of the upper end of the split housing and whose output shaft is axially fixedly connected to the end of the worm gear.

[0009] More preferably, the stirring control assembly includes a limiting groove provided on the outer wall of the meat paste stirring rod along the vertical height direction of the split housing, a transmission bevel gear sleeved on the meat paste stirring rod and located below the height adjustment sleeve, a transmission sleeve fixed above the transmission bevel gear and sleeved on the meat paste stirring rod, a transmission block fixed on the inner wall of the transmission sleeve and movably embedded in the limiting groove, a second rotary bearing provided between the inner wall of the split housing and the transmission sleeve, a drive bevel gear rotating on the rear side of the split housing and located below the second rotary bearing and meshing with the transmission bevel gear, and a drive shaft whose front end is axially fixedly connected to the drive bevel gear and whose rear end extends out of the rear side of the split housing.

[0010] More preferably, the meat paste stirring rod is rotatably sleeved below the transmission bevel gear, and a third rotating bearing is embedded in the cover plate and rotatably connected to the central sleeve. The outer wall of the central sleeve is provided with anti-detachment protrusions that abut against the lower side of the transmission bevel gear and the upper side of the third rotating bearing, respectively.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model rotates the retracting screw, which drives the retracting assembly to move upward along the spiral direction of the retracting screw, thereby synchronously driving the meat paste stirring rod to move upward. This causes the rod groove 11 on the meat paste stirring rod to fit into the retracting screw, thereby driving the meat paste stirring rod to retract during the rotation of the retracting screw in place. This solves the problem that the retracting screw needs to extend out of the upper side of the split housing during the retraction process.

[0013] 2. This utility model uses a horizontally arranged drive motor to drive the retracting screw to rotate, thereby adjusting the height of the meat paste stirring rod through the motor without increasing the height of the split machine casing, which facilitates the operator's control.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment of a fish ball machine stirring rod height adjustment device is installed on the fish ball machine housing 11 and detachably connected to the meat paste stirring rod 1 on the fish ball machine. It includes a split-type housing 2 movably sleeved above the meat paste stirring rod 1 and detachably connected to the front side of the fish ball machine housing 11 by screws; a cover plate 3 threadedly connected to the lower end of the split-type housing 2; a retracting screw 4 rotatably installed inside the split-type housing 2; a retracting component 5 installed inside the split-type housing 2 and used to drive the upper part of the meat paste stirring rod 1 and the lower part of the retracting screw 4; a retracting control component 6 installed above the split-type housing 2 and used to drive the retracting screw 4 to rotate; and a stirring control component 7 installed in the middle of the split-type housing 2 and used to drive the meat paste stirring rod 1 to rotate.

[0023] A rod retraction groove 11 is provided above the meat paste stirring rod 1 along the vertical height direction of the split-type machine casing 2;

[0024] The retraction assembly 5 includes a pair of sliding rails 51 located on opposite sides of the inner wall of the split housing 2 along the vertical height direction; a movable sleeve 52 movably sleeved on the lower part of the retraction screw 4 along the vertical height direction of the split housing 2; a height adjustment sleeve 53 detachably connected to the movable sleeve 52 and threadedly connected to the retraction screw 4 and sleeved on the retraction screw 4; a pair of limiting members 54 respectively fixed on both sides of the outer wall of the movable sleeve 52 and respectively embedded in the corresponding sliding rails 51; a first rotating bearing 55 located between the lower part of the inner wall of the height adjustment sleeve 53 and the outer wall of the meat paste stirring rod 1; and a nut sleeve 56 threadedly connected to the upper end of the meat paste stirring rod 1.

[0025] When this product is in use, by rotating the retracting screw 4, the height adjusting sleeve 53 is moved up along the spiral direction, thereby causing the movable sleeve 52 to move up synchronously along the sliding track 51. This causes the first rotating bearing 55 inside the movable sleeve 52 to support the nut sleeve 56 fixed on the meat paste stirring rod 1 and move up together. Thus, without changing the height position of the retracting screw 4, the meat paste stirring rod 1 is moved up, and the rod retraction groove 11 on the meat paste stirring rod 1 is put on from the lower end of the retracting screw 4, thereby reducing the distance between the lower end of the meat paste stirring rod 1 and the lower end of the retracting screw 4.

[0026] like Figure 1 and Figure 3 As shown, the tool retraction control assembly 6 includes a turbine 61 fixedly sleeved on the upper end of the tool retraction screw 4, a worm gear 62 rotatably disposed in the upper part of the split housing 2 and meshing with the turbine 61, and a drive motor 63 fixedly disposed on the rear side of the upper end of the split housing 2 and whose output shaft is axially fixedly connected to the end of the worm gear 62.

[0027] When in use, this product is activated by starting the drive motor 63 to drive the worm gear 62 to rotate, which in turn drives the meshing turbine 61 to rotate synchronously. This achieves the effect of controlling the rotation of the retracting screw 4 through the horizontally mounted drive motor 63, without increasing the height of the split housing 2, thus making it convenient for the operator to use.

[0028] like Figure 1 , Figure 3 and Figure 5As shown, the stirring control assembly 7 includes a limiting groove 71 provided on the outer wall of the meat paste stirring rod 1 along the vertical height direction of the split housing 2, a transmission bevel gear 72 sleeved on the meat paste stirring rod 1 and located below the height adjustment sleeve 53, a transmission sleeve 73 fixed above the transmission bevel gear 72 and sleeved on the meat paste stirring rod 1, a transmission block 74 fixed on the inner wall of the transmission sleeve 73 and movably embedded in the limiting groove 71, a second rotary bearing 75 provided between the inner wall of the split housing 2 and the transmission sleeve 73, a drive bevel gear 76 rotating on the inner rear side of the split housing 2 and located below the second rotary bearing 75 and meshing with the transmission bevel gear 72, and a drive shaft 77 whose front end is axially fixedly connected to the drive bevel gear 76 and whose rear end extends out of the rear side of the split housing 2.

[0029] When this product is in use, the drive source inside the fish ball forming machine drives the drive shaft 77 to rotate, thereby controlling the drive bevel gear 76 to drive the transmission bevel gear 72 to rotate, so that the transmission sleeve 73, which is fixedly connected to the transmission bevel gear 72, rotates synchronously, causing the transmission component 74 on the inner wall of the transmission sleeve 73 to apply a pushing force in the same direction to the inner wall of the limiting groove 71 of the meat paste stirring rod 1, thereby driving the meat paste stirring rod 1 to rotate.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, the meat paste stirring rod 1 is rotatably sleeved with a central sleeve 8 below the transmission bevel gear 72. The cover plate 3 is embedded with a third rotating bearing 9 that is rotatably connected to the central sleeve 8. The outer wall of the central sleeve 8 is provided with anti-detachment protrusions 10 that abut against the lower side of the transmission bevel gear 72 and the upper side of the third rotating bearing 9 respectively.

[0031] When this product is in use, the anti-disengagement protrusion 10 of the central sleeve 8 placed between the transmission bevel gear 72 and the third bearing 9 applies an upward supporting force to the lower surface of the transmission bevel gear 72 to prevent the transmission bevel gear 72 from sliding down and disengaging from the drive bevel gear 76, thus preventing the stirring from failing.

[0032] The working principle of this device is as follows:

[0033] Step 1: Place the central sleeve 8 onto the meat paste stirring rod 1, then hold the transmission sleeve 73 with one end of the transmission bevel gear 72 facing down, and then slip it onto the meat paste stirring rod 1 from the bottom. Insert the transmission component 74 on the inner wall of the transmission sleeve 73 into the limiting groove 71 until the lower side of the transmission bevel gear 72 abuts against the upper side of the anti-detachment protrusion 10. Then, place the second rotating bearing 75 onto the outer wall of the transmission sleeve 73.

[0034] Step 2: Install the first rotating bearing 55 inside the movable sleeve 52, then slide the movable sleeve 52 onto the upper end of the meat paste stirring rod 1, and then screw the nut sleeve 56 into the upper end of the meat paste stirring rod 1, so that the first rotating bearing 55 inside the movable sleeve 52 supports the nut sleeve 56, so that the meat paste stirring rod 1 and the movable sleeve 52 move up and down synchronously. Then, align the limiting parts 54 on both sides of the movable sleeve 52 with the corresponding sliding rails 51 and slide them into the interior of the upper part of the split housing 2. Finally, fix the height adjusting sleeve 53 to the movable sleeve 52 with screws.

[0035] Step 3: Slide the lower part of the split-type housing 2 upwards from the lower end of the meat paste stirring rod 1, and fix it to the upper part of the split-type housing 2 with screws. Then, install the third rotating bearing 9 on the cover plate 2, slide the cover plate 2 upwards from the lower end of the meat paste stirring rod 1, and fix it to the lower end of the split-type housing 2 with threads. At this time, the upper side of the third rotating bearing 9 abuts against the lower side of the anti-detachment protrusion 10. Then, install the split-type housing 2 on the fish ball forming machine with screws, and extend the drive bevel gear 76 into the split-type housing 2 from the rear side. By rotating the drive shaft 77, the drive bevel gear 76 is engaged with the transmission bevel gear 72.

[0036] Step 4: When it is time to cut, start the drive motor 63, which drives the worm gear 62 to rotate axially. This causes the turbine 61, which is meshed with the worm gear 62, to drive the retracting screw 4 to rotate synchronously. This causes the height adjusting sleeve 53, which is threadedly connected to the retracting screw 4, to move downward along the spiral direction. The movable sleeve 52, which is fixedly connected to the height adjusting sleeve 53, moves downward synchronously with the height adjusting sleeve 53. This causes the first rotating bearing 55 of the supporting nut sleeve 56 to move downward synchronously, thereby driving the meat paste stirring rod 1 to move downward.

[0037] Step 5: After lowering the meat paste stirring rod 1 to the appropriate position, the drive source inside the fish ball forming machine drives the drive shaft 77 to rotate, thereby controlling the drive bevel gear 76 to drive the transmission bevel gear 72 to rotate, so that the transmission sleeve 73, which is fixedly connected to the transmission bevel gear 72, rotates synchronously, causing the transmission component 74 on the inner wall of the transmission sleeve 73 to apply a pushing force in the same direction to the inner wall of the limiting groove 71 of the meat paste stirring rod 1, thereby driving the meat paste stirring rod 1 to rotate.

[0038] Step 6: When the knife needs to be retracted after use, control the drive motor 63 to drive the worm gear 62 to rotate in the opposite direction, causing the turbine 61 to drive the retraction screw 4 to rotate in the opposite direction. This causes the retraction screw 4 to drive the height adjustment sleeve 53 connected to it to move upward along the spiral direction, so that the first rotating bearing 55 supports the nut cap 55 to move upward, thereby driving the meat paste stirring rod 1 to move upward synchronously, and the rod groove 11 on the meat paste stirring rod 1 to fit on the lower part of the retraction screw 4, completing the knife retraction operation.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
