Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a bread cutting device. Background Technology

[0002] Bread cutting equipment, as a common mechanical device in the food processing industry, is widely used in baking factories, central kitchens, and catering establishments to achieve standardized slicing of bread products. Traditional commercial bread cutting equipment typically employs a multi-blade assembly structure with fixed spacing, using a mechanical transmission system to drive the blade assembly to cut the bread synchronously.

[0003] However, the blade spacing of existing bread cutting equipment cannot be adjusted, and a single machine can only produce bread slices of a fixed thickness. When it is necessary to change the slice thickness, the machine must be stopped to replace the entire blade assembly, or the position of each blade must be adjusted to change the blade spacing, which is inconvenient to use. Utility Model Content

[0004] In view of this, the present invention aims to provide a bread cutting device that can change the distance between each blade to adjust the thickness of the bread slice.

[0012] The sliders of the upper adjustment assembly and the sliders of the lower adjustment assembly can be connected to the upper and lower ends of each blade respectively through the transmission assembly, and the drive unit can drive each blade to reciprocate along the height direction through the transmission assembly.

[0013] Furthermore, each of the slide grooves surrounds the rotating shaft in the same direction and is spaced apart along the axial direction of the rotating shaft, and each slide groove has a first end and a second end; the relationship between the distance L1 between the first ends of each slide groove and the distance L2 between the second ends of each slide groove satisfies: L1 < L2.

[0014] Furthermore, synchronous pulleys are provided at both ends of the same side of the two rotating shafts, a synchronous belt is wound around the two synchronous pulleys, and a first motor connected to either of the rotating shafts is provided on the fixed plate.

[0015] Furthermore, the transmission assembly includes multiple swing seats, each swing seat corresponding to each slider and rotatably connected to each slider; the multiple swing seats include multiple upper swing seats connected to the upper adjustment assembly and multiple lower swing seats connected to the lower adjustment assembly; the upper and lower ends of the blade are respectively hinged to the upper swing seats and the lower swing seats, so that the blade, the upper swing seats, and the lower swing seats constitute a first linkage mechanism; the driving unit can drive each swing seat to swing and drive each blade to reciprocate.

[0016] Furthermore, the swing seat has a first hinge hole and a second hinge hole; the first hinge hole of each swing seat is located on the side close to the feed port, and the second hinge hole of each swing seat is located on the side close to the discharge port; in two adjacent blades, the upper and lower ends of one blade are hinged to the two first hinge holes of the corresponding upper swing seat and the lower swing seat, and the upper and lower ends of the other blade are hinged to the two second hinge holes of the corresponding upper swing seat and the lower swing seat.

[0017] Furthermore, a connecting arm is provided between each of the swing seats and each of the blades; the connecting arm has a hinge end that is hinged to the first hinge hole or the second hinge hole corresponding to the swing seat, and a connecting end that is connected to the end of the blade, and from the height direction, the connecting end is located between the first hinge hole and the second hinge hole.

[0018] Furthermore, the transmission assembly also includes four synchronizing rods, with the first hinge hole and the second hinge hole of each swing seat sleeved on the corresponding synchronizing rod, and each swing seat being able to slide along the synchronizing rod as the corresponding slider moves.

[0019] Furthermore, the transmission assembly also includes a first link and a second link;

[0020] The upper and lower ends of the first connecting rod are respectively hinged to two synchronous rods passing through each of the first hinge holes, and the upper and lower ends of the second connecting rod are respectively hinged to two synchronous rods passing through each of the second hinge holes, so that the first connecting rod, the second connecting rod, the upper swing seat and the lower swing seat constitute the second linkage mechanism.

[0021] Furthermore, the drive unit includes a second motor, an eccentric wheel, and a rocker arm; the eccentric wheel is connected to the output shaft of the second motor, and one end of the rocker arm is sleeved on the eccentric wheel, while the other end is hinged to any of the swing seats.

[0022] Furthermore, the housing is provided with a conveying device, which can convey the bread to be cut to the inlet and convey the cut bread to the outside through the outlet.

[0023] Compared with the prior art, this utility model has the following advantages:

[0024] The bread cutting device of this utility model, through the setting of multiple grooves and multiple sliders on the rotating shaft, the rotating shaft is driven to rotate, and the side wall of each groove pushes against the sliding part of the corresponding slider, so that each slider slides along the axial direction of the rotating shaft, and the blades connected to the sliders can move with the movement of the sliders, thereby changing the distance between each blade and realizing the adjustment of the thickness of the bread slice.

[0025] Furthermore, the slides are distributed around the rotating shaft, and the distance between the first and second ends of each slide is different. This causes the distance between the slides to change as the sliding part of the slider moves along the slide, thus adjusting the distance between the blades, i.e., the thickness of the bread slice. The two rotating shafts are connected by a synchronous belt drive, ensuring that the rotation of the two shafts is synchronized and that the distance between the upper and lower ends of each blade changes synchronously, preventing the blades from bending. At the same time, the swing seat allows the upper swing seat, lower swing seat, and blades to form a first linkage mechanism, and the swing of the swing seat drives the blades to reciprocate.

[0026] In addition, the swing seat has a first hinge hole and a second hinge hole. Two adjacent blades are respectively hinged to the first hinge hole and the second hinge hole of the adjacent swing seat, driving the two adjacent blades to move in opposite directions to improve cutting efficiency. A connecting arm is provided between each swing seat and each blade, which allows two adjacent blades to approach each other and partially overlap in the axial direction of the rotating shaft. The first hinge hole and the second hinge hole of each swing seat are both connected to the corresponding synchronizing rod, which can ensure the synchronous swing of each swing seat.

[0027] Furthermore, the first connecting rod connects two synchronous rods passing through the first hinge hole, while the second connecting rod connects two synchronous rods passing through the second hinge hole. The first and second connecting rods act as links in the second linkage mechanism, driving the upper and lower swing seats to swing synchronously, thus preventing damage to the blades due to insufficient rigidity. The drive unit includes a second motor, an eccentric wheel, and a rocker arm. The eccentric wheel can drive the swing seats to swing at high frequency via the rocker arm. A conveying device is provided on the housing to facilitate the feeding and discharging of bread. Attached Figure Description

[0049] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] This embodiment relates to a bread cutting device, the overall structure of which is as follows: Figure 1 , Figure 2As shown, it includes a housing 1 and a bread-cutting mechanism disposed within the housing 1.

[0051] The housing 1 has an inlet and an outlet located on opposite sides of the cutting assembly. The bread to be cut enters the housing 1 through the inlet and is cut by the cutting assembly, while the cut bread is discharged out of the housing 1 through the outlet. The cutting mechanism includes two spaced-apart fixed plates 2, and an adjusting assembly 3, a transmission assembly, a blade 5, and a drive unit 9 located between the two fixed plates 2. Figure 2 , Figure 4 As shown, the adjustment assembly 3 includes an upper adjustment assembly 3a and a lower adjustment assembly 3b arranged at intervals along the height direction.

[0052] The upper adjustment component 3a and the lower adjustment component 3b both include a rotating shaft 301 rotatably connected to two fixed plates 2 at both ends, multiple sliders 302 sleeved on the rotating shaft 301, and a guide structure 303. Figure 6 As shown, the rotating shaft 301 is provided with multiple grooves 3011 corresponding to each slider 302, and the slider 302 is provided with a sliding part 3021 that is slidably engaged in the corresponding groove 3011. When the rotating shaft 301 is driven to rotate, it can drive each slider 302 to slide along the axial direction of the rotating shaft 301 under the guidance of the guide structure 303, and adjust the distance between two adjacent sliders 302. Each slider 302 of the upper adjustment component 3a and each slider 302 of the lower adjustment component 3b can be connected to the upper and lower ends of each blade 5 respectively through the transmission component, and the driving part 9 can drive each blade 5 to reciprocate along the height direction through the transmission component.

[0053] As configured above, when the rotating shaft 301 is rotated, the sidewalls of each groove 3011 on the rotating shaft 301 can push against the sliding portion 3021 of the corresponding slider 302, causing the slider 302 to slide along the axial direction of the rotating shaft 301 and change the distance between the sliders 302. Since each blade 5 is connected to each slider 302 through a transmission assembly, when each slider 302 on the upper adjustment assembly 3a and the lower adjustment assembly 3b moves, it can drive each blade 5 to move, thereby changing the distance between the blades 5. At the same time, the reciprocating motion of the blades 5 is used to slice the bread, thereby adjusting the thickness of the bread slice.

[0054] Based on the above overview, specifically, in this embodiment, the blade 5 is strip-shaped with a relatively long dimension in the height direction to accommodate the size of the bread to be cut. Furthermore, by incorporating an upper adjustment structure, a lower adjustment mechanism, and a transmission assembly, the upper and lower ends of the blade 5 can be connected. The distance between the ends of each blade 5 can be adjusted to improve the fixing effect of the blades 5 and ensure the accuracy of the blade spacing adjustment.

[0055] In addition, the blade 5 in this embodiment has a serrated cutting edge, and the cutting edge is set towards the feed port. Furthermore, the guide structure 303 in this embodiment is a guide rod, and each slider 302 is sleeved on the guide rod. The guide rod can restrict the rotation of the slider 302 and prevent the slider 302 from rotating synchronously with the rotating shaft 301, which would cause the adjustment component to fail.

[0056] In this embodiment, as Figure 3 As shown, each slide groove 3011 surrounds the rotating shaft 301 in the same direction and is spaced apart along the axial direction of the rotating shaft 301. Each slide groove 3011 has a first end 3011a and a second end 3011b. The distance L1 between the first ends 3011a of each slide groove 3011 and the distance L2 between the second ends 3011b of each slide groove 3011 satisfy the following relationship: L1 < L2. It can be understood that the slide grooves 3011 are arranged around the rotating shaft 301 in the same direction so that when the rotating shaft 301 rotates in a preset direction, the sliding portion 3021 of each slider 302 can be pushed by the corresponding slide groove 3011, causing each slider 302 to move.

[0057] At the same time, when the sliding part 3021 of each slider 302 is located at the first end 3011a of each groove 3011, such as Figure 4 As shown, the spacing between each slider 302 is the spacing L1 between each first end 3011a, that is, the spacing between each blade 5 is L1. When the sliding portion 3021 of each slider 302 is located at the second end 3011b of each groove 3011, as... Figure 5 As shown, the spacing between each slider 302 is the spacing L2 between each second end 3011b, that is, the spacing between each blade 5 is L2.

[0058] Furthermore, the relationship between L1 and L2 satisfies L1 < L2, indicating that when the rotating shaft 301 rotates in the preset direction, causing the sliding part 3021 of the slider 302 to move from the first end 3011a to the second end 3011b along the slide groove 3011, the distance between each slider 302 gradually increases, and the distance between each blade 5 gradually increases, thereby increasing the thickness of the bread slice. Similarly, when the rotating shaft 301 rotates in the opposite direction in the preset direction, the distance between each slider 302 gradually decreases, and the distance between each blade 5 gradually decreases, thereby decreasing the thickness of the bread slice. This achieves the adjustment of the distance between the blades 5.

[0059] In specific implementation, the spacing between each slide groove 3011 in this embodiment increases uniformly from the first end 3011a to the second end 3011b. That is, when the sliding part 3021 of each slider 302 is at any position of each slide groove 3011, the spacing between each slider 302 is the same, so as to adjust the thickness of the bread slice between L1 and L2 and ensure that the thickness of the sliced ​​bread is the same, thus ensuring the slicing effect of the bread.

[0060] Furthermore, in this embodiment, the spacing between the grooves 3011 changes uniformly from the first end 3011a to the second end 3011b. Each groove 3011 is a spiral groove surrounding the rotating shaft 301, and the leads of each groove 3011 are different. When there is an even number of grooves 3011, the lead of each groove 3011 is not zero, and each slider 302 will slide along the axial direction of the rotating shaft 301. When there is an odd number of grooves 3011, there is one groove 3011 with a lead of zero, and the slider 302 corresponding to this groove 3011 will not slide circumferentially along the rotating shaft 301.

[0061] Since the upper adjustment component 3a and the lower adjustment component 3b are connected to the upper and lower ends of each blade 5 through the transmission component, it is necessary to ensure that the distance between the upper and lower ends of each blade 5 changes synchronously to avoid bending of the blade 5.

[0062] Therefore, such as Figure 2 As shown, in this embodiment, synchronous pulleys 3012 are provided at both ends of the same side of the two rotating shafts 301, and a synchronous belt 3013 is wound around the two synchronous pulleys 3012. A first motor 201 connected to either rotating shaft 301 is provided on the fixing plate 2. By setting the synchronous belt 3013 and the synchronous pulleys 3012, the synchronous rotation of the two rotating shafts 301 can be ensured, so as to ensure that the distance between the upper and lower ends of each blade 5 changes synchronously, avoid the blade 5 from bending, and improve the stability of the blade 5 during the bread slice thickness adjustment process.

[0063] As a specific form of implementation, such as Figure 6 As shown, the transmission assembly of this embodiment includes multiple swing seats 4, each swing seat 4 corresponding to each slider 302 and rotatably connected to each slider 302. The multiple swing seats 4 include multiple upper swing seats 4a connected to the upper adjustment assembly 3a, and multiple lower swing seats 4b connected to the lower adjustment assembly 3b.

[0064] In this design, the upper and lower ends of the blade 5 are hinged to the upper swing seat 4a and the lower swing seat 4b, respectively, forming the first linkage 7 mechanism. The drive unit 9 can drive each swing seat 4 to swing, thereby driving each blade 5 to reciprocate. Specifically, the first linkage 7 mechanism is a double rocker structure, with the upper swing seat 4a and the lower swing seat 4b serving as two rockers, and the blade 5 serving as the connecting rod between the two rockers. When any swing seat 4 is driven to swing, it can drive the blade 5 to reciprocate, thereby achieving the cutting of bread by the blade 5. At the same time, the reciprocating speed of the blade 5 is relatively fast, which can improve the cutting efficiency of bread. In a specific implementation, the slider 302 of this embodiment is disc-shaped, and the swing seat 4 is rotatably sleeved on the slider 302, so that the slider 302 serves as the pivot 301 of the swing seat 4.

[0065] Understandably, when each swing seat 4 is driven to swing synchronously, each blade 5 will move upward and then downward along the height direction simultaneously to cut the bread. During this process, the cut portion of the bread will move up and down with the blade 5 to some extent due to the movement of the blade 5, and the movement of the bread with the blade 5 will reduce the cutting efficiency of the blade 5.

[0066] Therefore, to further improve the bread cutting efficiency, the swing seat 4 in this embodiment has a first hinge hole 401 and a second hinge hole 402. The first hinge hole 401 of each swing seat 4 is located on the side near the feed inlet, and the second hinge hole 402 of each swing seat 4 is located on the side near the discharge outlet. In two adjacent blades 5, the upper and lower ends of one blade 5 are hinged to the two first hinge holes 401 of the corresponding upper swing seat 4a and lower swing seat 4b, and the upper and lower ends of the other blade 5 are hinged to the two second hinge holes 402 of the corresponding upper swing seat 4a and lower swing seat 4b.

[0067] Thus, the two adjacent blades 5, together with their corresponding upper swing seats 4a and lower swing seats 4b, form two of the aforementioned first linkage 7 mechanisms. During the synchronous swinging of each swing seat 4, the two adjacent blades 5 move in opposite directions, and the cutting forces exerted by the two blades 5 on the bread are also in opposite directions, thereby preventing the bread from moving up and down with the blades 5 and improving the efficiency of cutting the bread.

[0068] Furthermore, in any two adjacent blades 5, the two blades 5 are respectively hinged at the first hinge hole 401 and the second hinge hole 402, with a certain distance between the two hinge holes. This causes the bread to first contact the portion of the blade 5 connected to the first hinge hole 401, and then contact the remaining blades 5. Between contacts between the bread and each blade 5, it will still move up and down with some of the blades 5, resulting in a decrease in cutting efficiency.

[0069] Therefore, in this embodiment, a connecting arm 501 is provided between each swing seat 4 and each blade 5. The connecting arm 501 has a hinge end that hinges to the first hinge hole 401 or the second hinge hole 402 of the corresponding swing seat 4, and a connecting end that connects to the end of the blade 5. From a height perspective, the connecting end is located between the first hinge hole 401 and the second hinge hole 402. Through the connection arm 501, each blade 5 can be hinged to the corresponding swing seat 4 via the connecting arm 501. Simultaneously, the connecting end of the connecting arm 501 is located between the first hinge hole 401 and the second hinge hole 402, allowing adjacent blades 5 to at least partially overlap in the axial direction of the rotating shaft 301. This enables the bread to simultaneously contact the two blades 5 moving in opposite directions, limiting the movement of the bread with the blades 5 and further improving cutting efficiency.

[0070] In specific implementation, the connecting end of the connecting arm 501 in this embodiment is provided with a groove for mounting the end of the blade 5, and the groove is provided with a through hole for the fixing pin to pass through. The groove can restrict the relative rotation between the blade 5 and the connecting arm 501, preventing transmission component failure. It also facilitates the replacement of the blade 5 and is beneficial for the inspection and maintenance of the cutting mechanism. Of course, the connecting end can be provided with other structures for connecting to the end of the blade 5, as long as they have good connection strength and can prevent relative rotation between the connecting arm 501 and the blade 5.

[0071] As a specific implementation, to ensure the synchronous swing of each swing seat 4, the transmission assembly of this embodiment further includes four synchronizing rods 6. The first hinge hole 401 and the second hinge hole 402 of each swing seat 4 are sleeved on the corresponding synchronizing rod 6, and each swing seat 4 can slide along the synchronizing rod 6 as the corresponding slider 302 moves. By having each swing seat 4 pass through the synchronizing rod 6, the synchronous rotation of each swing seat 4 can be ensured, avoiding the need for the drive unit 9 to control each swing seat 4 individually.

[0072] The rigidity of the blade 5 is limited. When the blade 5 is used as a link in the aforementioned first link 7 mechanism, it is prone to bending, which affects the synchronous swinging of the upper swing seat 4a and the lower swing seat 4b. Therefore, the transmission assembly of this embodiment also includes the first link 7 and the second link 8.

[0073] The upper and lower ends of the first connecting rod 7 are respectively hinged to two synchronous rods 6 passing through each of the first hinge holes 401, and the upper and lower ends of the second connecting rod 8 are respectively hinged to two synchronous rods 6 passing through each of the second hinge holes 402, so that the first connecting rod 7, the second connecting rod 8, the upper swing seat 4a, and the lower swing seat 4b constitute the second connecting rod 8 mechanism. Through the arrangement of the first connecting rod 7 and the second connecting rod 8, when any swing seat 4 is driven to swing, it can drive the other swing seats 4 to swing through the first connecting rod 7 and the second connecting rod 8, avoiding the blade 5 from bending and being damaged due to force, and preventing the synchronous swinging of the upper swing seat 4a and the lower swing seat 4b from being affected. In specific implementation, in this embodiment, the first connecting rod 7 and the second connecting rod 8 are both configured as two, respectively located on the outside of the two fixed plates 2 and connected to the two ends of each synchronous rod 6. At the same time, through slots are formed on the two fixed plates 2 to avoid the synchronous rods 6.

[0074] Based on this, the drive unit 9 of this embodiment includes a second motor 901, an eccentric wheel 902, and a rocker arm 903. The eccentric wheel 902 is connected to the output shaft of the second motor 901, and one end of the rocker arm 903 is sleeved on the eccentric wheel 902, while the other end is hinged to any swing seat 4. The second motor 901 drives the eccentric wheel 902 to rotate, which in turn drives the end of the rocker arm 903 that is hinged to the swing seat 4 to reciprocate. This causes the rocker arm 903 to drive the swing seat 4 to swing, resulting in a higher swing frequency for the swing seat 4. This, in turn, increases the reciprocating speed of each blade 5, further improving the bread-cutting speed.

[0075] In practical implementation, to facilitate the connection between the rocker arm 903 and the swing seat 4, the rocker arm 903 can be hinged to any of the synchronizing rods 6. At this time, the rocker arm 903 is hinged to each upper swing seat 4a or lower swing seat 4b through the synchronizing rod 6, driving the synchronizing rod 6 to reciprocate and realize the swing of each swing seat 4, thereby facilitating the connection between the rocker arm 903 and the swing seat 4.

[0076] Finally, the housing 1 in this embodiment is equipped with a conveying device, which can transport the bread to be cut to the inlet and the cut bread to the outside through the outlet, so as to facilitate the feeding and discharging of bread. In specific implementation, the conveying device in this embodiment includes two conveyor belts 101 respectively disposed at the inlet and outlet. At the same time, two support bars 202 are provided between the two fixed plates 2, and the two support bars 202 are respectively disposed between the blade 5 and the two conveyor belts 101. Since the adjustment component 3 and the transmission component require sufficient space for operation, there is a certain distance between the two conveyor belts 101 and the blade 5. Through the setting of the support bars 202, the support bars 202 can fill the gap between the transmission belt and the blade 5 and provide support for the bread, preventing the end of the bread from getting stuck in the gap.

[0077] In summary, the bread cutting device of this embodiment, through the arrangement of multiple grooves 3011 and multiple sliders 302 on the rotating shaft 301, drives the rotating shaft 301 to rotate, causing the sidewalls of each groove 3011 to push against the sliding part 3021 of the corresponding slider 302, so that each slider 302 slides along the axial direction of the rotating shaft 301. Each blade 5 connected to the slider 302 can move with the movement of the slider 302, thereby changing the spacing between each blade 5 and realizing the adjustment of the thickness of the bread slice.

[0078] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
