Description

Technical Field

[0001] The utility model relates to the technical field of chopping machines, in particular to a chopping machine with adjustable width. Background Art

[0002] With the popularization of hot pot culture and the growth of consumer demand, the production scale of hot pot base materials has been continuously expanding, and the requirements for production efficiency and product quality have also become higher and higher. The traditional manual cutting method can no longer meet the needs of large-scale production. Therefore, the hot pot base material chopping machine came into being.

[0003] There are many different focuses on the optimization of the hot pot base material chopping device. For example, a hot pot base material cutting device disclosed in a Chinese patent (publication number: CN220576062U) includes a chassis. A containing tray is movably arranged in the chassis, and a water cooling structure is arranged on the periphery of the chassis; the top port of the chassis is covered with an assembly bracket in a flip-up manner through a hinge seat, and a cutting frame is movably arranged up / down on the assembly bracket, which is used to solve the problem that some existing cutting devices are not convenient to accurately and quickly place the solidified hot pot base material directly below the base material placing table of the moving cutting device, resulting in easy deviation of the hot pot base material during the cutting process and uneven cutting sizes.

[0004] This device is provided with an operating handle at the top of the cutting frame. After the liquid hot pot base material in the containing tray cools and solidifies, the assembly bracket can be flipped and covered on the top of the chassis, so that the cutting frame is located directly above the containing tray. Then, by holding the operating handle and pressing down the cutting frame, the tension spring is stretched, and the cutting frame moves downward and presses into the containing tray to cut the solidified hot pot base material in the containing tray. However, this cutting method is manual cutting. Although many pieces can be cut at one time, it still requires a lot of manpower and has low efficiency. Since the cutting tool is an integral cutting tool, the size of the cut hot pot base material is fixed, and the adaptability cannot be changed and is not high. Therefore, a chopping machine with adjustable width is proposed to solve the above problems. Content of the Utility Model

[0008] The moving assembly includes a fixed frame fixed to the top of the inner cavity of the box body. Two moving tools are movably connected between the front and rear side walls of the fixed frame. One end of each of the two moving tools penetrates the box body and is fixed with a threaded sleeve. The two threaded sleeves are respectively threadedly connected to the outer surfaces of the driven rod and the rotating rod. The other ends of the two moving tools are both fixed with moving blocks slidably connected to the inner wall of the box body. T-shaped blocks are fixed to the opposite sides of the two threaded sleeves. A fixed tool is fixed to the inner side of the fixed frame.

[0009] Furthermore, both groups of pulley assemblies are composed of a driving wheel, a driven wheel and a belt. The two driving wheels are fixed to the outer surface of the driving rod, the two driven wheels are respectively fixed to the outer surfaces of the two transmission rods, and the outer surfaces of the driving wheel and the driven wheel are connected by a belt for transmission.

[0010] Furthermore, sliding teeth are fixed to the outer surfaces of the two transmission rods, fixed teeth with the same size and quantity as the sliding teeth on the outer surfaces of the two transmission rods are fixed to the sides of the driven rod and the rotating rod close to the servo motor, and movable teeth adapted to both the sliding teeth and the fixed teeth are fixed to the inner side walls of the control components.

[0011] Furthermore, the two control components include connecting bearings clamped to the outer surfaces of the transmission rods. A clamping sleeve is fixed to the inner side of the connecting bearing. L-shaped racks are fixed to the opposite sides of the two connecting bearings. Moving grooves for the racks to move are opened on the inner side wall of the box body near the two control components, and a switch groove opened on the outer wall of the box body is communicated with the moving groove.

[0012] Furthermore, a fixed rod is rotatably connected between the upper and lower side walls of the two moving grooves through a movable bearing. A driven gear and a driving gear meshing with the rack are respectively fixed to the outer surfaces of the two fixed rods from top to bottom. A switch is movably connected in the switch groove, and the switch meshes with the driven gear.

[0013] Furthermore, the switch is composed of a connecting shaft rotatably connected in the switch groove, a driving gear and a dial plate. The outer surface of the connecting shaft is fixed with the driving gear. The driving gear meshes with the driven gear, and a dial plate is fixed to the right side of the driving gear.

[0018] The width-adjustable chopping machine places the hot pot base on a base, starts a servo motor and then toggles a switch, wherein a dial plate on the switch can be hidden in a switch slot and stuck in the switch slot, thereby avoiding the problem of power failure caused by accidentally touching the switch, so that the control component connects the transmission rod with the corresponding driven rod and rotating rod, and at the same time, under the transmission action of the pulley assembly, the rotational force of the box body causes the driven rod and the rotating rod to rotate, and the moving tool in the moving component is displaced by thread rotation and T-slot limiting. When the moving tool moves to a suitable position, the dial plate is toggled in the opposite direction, so that the control component no longer transmits the rotational force of the transmission rod to the driven rod and the rotating rod, and two electric push rods are started, which drive the width adjustment mechanism to cut downward, and the hot pot base is pushed out after the chopping is completed, thereby completing the chopping of the hot pot base. The device has high cutting efficiency, saves manpower and can adjust the cutting width, and the cutting size is more flexible, and it is more adaptable to pots of different sizes.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1 , a chopping machine with adjustable width in this embodiment includes a base 1. A U-shaped support frame 2 is fixed on the top of the base 1. Two electric push rods 3 are fixed on the inner side wall of the support frame 2. A width adjustment mechanism 4 for adjusting the chopping width is fixed at the bottom of the electric push rod 3.

[0027] In this embodiment, after placing the hot pot base on the base 1, the width adjustment mechanism 4 is started. After the width adjustment mechanism 4 is adjusted to a suitable position, the two electric push rods 3 are started. The two electric push rods 3 push the width adjustment mechanism 4 to achieve the chopping of the hot pot base.

[0028] Please refer to Figures 2 to 3 and Figure 5 , in order to achieve adjustable width of the chopping machine, the width adjustment mechanism 4 in this embodiment includes a box body 401 fixedly connected to the movable shaft of the electric push rod 3. A servo motor 402 is fixed on the right side of the box body 401. The output shaft of the servo motor 402 penetrates the box body 401 and is fixed with a driving rod 403. Two groups of pulley assemblies 407 for transmitting torque are movably connected to the outer surface of the driving rod 403.

[0029] Furthermore, both sets of pulley assemblies 407 are composed of a driving pulley 4071, a driven pulley 4072, and a belt 4073. Both driving pulleys 4071 are fixed to the outer surface of the driving rod 403, and both driven pulleys 4072 are fixed to the outer surfaces of the two transmission rods 409 respectively. The outer surfaces of the driving pulley 4071 and the driven pulley 4072 are connected by a belt 4073 in transmission. The setting of the pulley assembly 407 can achieve long-distance transmission, further reducing the weight of the device while ensuring the reliability of transmission.

[0030] In addition, the left inner wall of the box body 401 is rotatably connected with a driven rod 404 and a rotating rod 405 through a stable bearing. A moving assembly 406 for adjusting the position of the tool is provided between the driven rod 404 and the rotating rod 405. The right inner wall of the box body 401 is rotatably connected with two transmission rods 409 through a rotating bearing. Control assemblies 408 with one end respectively clamped to the two transmission rods 409 are provided on the outer surfaces of the driven rod 404 and the rotating rod 405. The control assembly 408 is used to control the power transmission. The set control assembly 408 can freely control the power transmission, thereby further controlling the displacement of the tool.

[0031] In addition, sliding teeth are fixed on the outer surfaces of the two transmission rods 409. Fixed teeth with the same size and quantity as the sliding teeth on the outer surfaces of the two transmission rods 409 are fixed on the sides of the driven rod 404 and the rotating rod 405 close to the servo motor 402. An active tooth adapted to both the sliding teeth and the fixed teeth is fixed on the inner side wall of the control assembly 408. The rotational force transmission is realized through the mutual clamping of the sliding teeth, the fixed teeth, and the active tooth. When the active tooth moves leftward, the power transmission can be disconnected.

[0032] Furthermore, the moving assembly 406 includes a fixed frame 4061 fixed to the top of the inner cavity of the box body 401. Two moving tools 4062 are movably connected between the front and rear side walls of the fixed frame 4061. One end of each of the two moving tools 4062 penetrates through the box body 401 and is fixed with a threaded sleeve 4063. The two threaded sleeves 4063 are respectively threadedly connected to the outer surfaces of the driven rod 404 and the rotating rod 405. The other ends of the two moving tools 4062 are both fixed with moving blocks 4065 slidably connected to the inner wall of the box body 401. T-shaped blocks 4064 are fixed on the opposite sides of the two threaded sleeves 4063. A fixed tool 4066 is fixed inside the fixed frame 4061. The setting of the T-shaped blocks 4064 and the moving blocks 4065 can prevent the moving tools 4062 from bending sideways during the movement, and at the same time can also limit the moving tools 4062 to prevent the moving tools 4062 from rotating along with the thread.

[0033] The fixing frame 4061 is provided with a stable groove for the movement of the moving block 4065. T-shaped grooves for the sliding of the T-shaped block 4064 are provided on the front and rear side walls of the box body 401. The stable groove and the T-shaped groove are provided to limit the moving cutter 4062 and define its moving direction to prevent the moving cutter 4062 from rotating.

[0034] The fixed cutter 4066 is composed of three transverse blades and one longitudinal blade. The longitudinal blade and the three transverse blades are both fixed to the fixing frame 4061. Relief grooves for the movement of the moving cutter 4062 are provided on the three transverse blades. The provision of the relief grooves can prevent the moving cutter 4062 from jamming during the movement process and at the same time limit the maximum displacement of the moving cutter 4062 to prevent the moving cutter 4062 from moving to other positions and affecting other parts.

[0035] External threads are fixed on the outer surfaces of the driven rod 404 and the rotating rod 405. Internal threads adapted to the external threads are fixed on the inner surface of the threaded sleeve 4063. The moving assembly 406 is composed of a main board and a moving rod. The main board is movably connected to the fixed cutter 4066. A moving rod passing through the fixing frame 4061 and fixed to the threaded sleeve 4063 is fixed at one end of the main board away from the moving block 4065. A long strip moving hole adapted to the moving rod is provided on the fixing frame 4061. The long strip hole allows the moving rod to slide therein and at the same time connects the main board and the threaded sleeve 4063.

[0036] In this embodiment, through the cooperation of the stable groove, the T-shaped groove and the relief groove, the degrees of freedom of the moving cutter 4062 are restricted to prevent the moving cutter 4062 from rotating following the driven rod 404 and the rotating rod 405.

[0037] Please refer to Figure 4 , in order to realize the opening and closing of the tool adjustment, the two control components 408 in this embodiment include connecting bearings 4081 clamped on the outer surface of the transmission rod 409. A clamping sleeve is fixed inside the connecting bearing 4081. Rack bars 4082 in an L shape are fixed on the opposite sides of the two connecting bearings 4081. Moving grooves for the movement of the rack bars 4082 are provided on the inner side wall of the box body 401 near the two control components 408. The moving grooves communicate with switch grooves opened on the outer wall of the box body 401. The provision of the moving grooves can place the moving positions of the rack bars 4082 in the box body 401 to further reduce the volume.

[0038] A fixed rod 4083 is movably connected between the upper and lower side walls of the two moving grooves through a movable bearing. A driven gear 4085 and a driving gear 4084 meshing with a rack 4082 are respectively fixed on the outer surfaces of the two fixed rods 4083 from top to bottom. A switch 4086 is movably connected in a switch groove. The switch 4086 meshes with the driven gear 4085. After the switch 4086 is toggled, the switch 4086 drives the driven gear 4085 to rotate. By setting the diameter of the driven gear 4085 to be smaller than the diameter of the switch 4086, the number of rotation circles of the driving gear 4084 is further increased, so as to achieve the purpose that when the switch 4086 rotates half a circle, the rack 4082 displaces a longer distance.

[0039] The switch 4086 is composed of a connecting shaft rotatably connected in the switch groove, a driving gear and a dial plate. The outer surface of the connecting shaft is fixed to the driving gear. The driving gear meshes with the driven gear 4085. A dial plate is fixed on the right side of the driving gear. The dial plate can facilitate the toggling of the switch 4086. At the same time, the dial plate can be snapped into the switch groove to realize a semi-hidden switch 4086, avoiding accidentally touching the switch 4086 and affecting the control component 408. Since the dial plate is snapped into the switch groove, it also plays a role of self-locking, improving the transmission stability.

[0040] It should be noted that through the cooperation of the belt pulley assembly 407 and the control component 408, the start and stop of the moving cutter 4062 are controlled. Through the clamping connection between the dial plate and the switch groove, self-locking is realized to further improve the transmission stability.

[0041] It can be understood that the servo motor 402 provides power for the width adjustment mechanism 4. The power is transmitted to the two transmission rods 409 through the belt pulley assembly 407. The switch 4086 on the control component 408 is toggled, so as to make the driven rod 404 and the rotating rod 405 integrated with the transmission rod 409 to realize power transmission. The dial plate on the switch 4086 is snapped into the switch groove to ensure the stability of power transmission. Under the cooperation of the stabilizing groove, the T-shaped groove and the relief groove, the moving cutter 4062 is urged to move horizontally to realize width adjustment. This adjustment method can improve the chopping flexibility while ensuring the chopping efficiency, and the hot pot base is cut into different sizes to fit different sizes of pots.

[0042] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and the circuit connection of the present utility model will not be further explained in detail.

[0043] The working principle of the above embodiment is as follows:

[0044] Place the hot pot base on the base 1, start the servo motor 402, and at the same time toggle the switch 4086. The switch 4086 drives the driven gear 4085. Since both the driven gear 4085 and the driving gear 4084 are fixed to the fixed rod 4083, the driving gear 4084 transmits the force to the rack 4082 to control the forward and backward displacement of the connecting bearing 4081. When the connecting bearing 4081 moves to the right and engages with the transmission rod 409, at this time the two transmission rods 409 are in a relatively integrated state with the driven rod 404 and the rotating rod 405 respectively through the control assembly 408, so that the force of the rotation of the transmission rod 409 can be transmitted to the driven rod 404 and the rotating rod 405, further controlling the start and stop of the driven rod 404 and the rotating rod 405. The driven rod 404 and the rotating rod 405 are respectively threadedly connected to the threaded sleeve 4063. Since the threaded sleeve 4063 is fixed to the moving cutter 4062, the movement and stop of the moving cutter 4062 are further controlled. When the moving cutter 4062 moves to the appropriate position, toggle the switch 4086 to the left and snap the dial into the switch slot to disconnect the rotating state of the driven rod 404 and the rotating rod 405. Since the dial is snapped into the switch slot, it can avoid accidentally touching the dial, and at the same time the stuck dial also plays a self-locking role, which can make the connection of the control assembly 408 more reliable. At the same time, start the two electric push rods 3. The electric push rods 3 push the width adjustment mechanism 4 to move downward as a whole, prompting the fixed cutter 4066 and the moving cutter 4062 to cut the hot pot base. After the cutting is completed, start the electric push rod 3. The electric push rod 3 pulls the width adjustment mechanism 4 to prompt the fixed cutter 4066 and the moving cutter 4062 to separate from the hot pot base, and then push out the hot pot base to complete the chopping of the hot pot base. After starting the servo motor 402, toggle the switch 4086 to prompt the moving cutter 4062 to move. After the movement is completed, toggle the switch 4086 back. Finally, start the electric push rod 3 to complete the cutting. Since the width is adjustable, it has better adaptability to cookers of different sizes, and can ensure the cutting quality while ensuring the efficiency, saving time and effort.

[0045] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0046] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
