Description

Technical Field

[0001] The present invention relates to the technical field of hamburger bun production, and in particular to a dividing and forming device and process for hamburger bun production. Background Art

[0002] The earliest hamburgers were mainly composed of two small round buns with a beef patty. In modern hamburgers, in addition to beef patties or other meat patties such as chicken or pork, the second layer of the round bun is also coated with butter, mustard, ketchup, salad dressing, etc., and then tomato slices, onions, pickles and other foods are added, so that the main and side dishes can be eaten at the same time; it is convenient to eat, delicious, and nutritious, and has become one of the best-selling staple foods in the world;

[0003] With the continuous development of science and technology, in the production of hamburger buns, the staff will first divide the kneaded dough into quantitative parts through a dividing and forming device, and then cook the divided small doughs, so as to facilitate the subsequent production of hamburgers; the existing public document CN218947766U-a cutting device for hamburger bun processing and the existing public document CN112293445A-a device for adjusting the size of dough, both disclose a cutting (slitting) device for kneaded dough, but the existing dough cutting device has the following deficiencies in actual use:

[0004] 1. The existing cutting device is a sealed structure when in use, which makes it inconvenient for the staff to clean the inside of the device after the cutting process is completed. After long-term use, bacteria will grow inside the device;

[0005] 2. Most of the existing cutting devices can only cut dough of fixed size when in use. However, the size of hamburger buns varies in actual demand, which makes the existing equipment unsuitable for the production of all hamburger buns, indirectly increasing the production cost;

[0006] 3. In addition, the existing dough is mainly kneaded by equipment, but the existing large-scale kneading equipment has certain deficiencies in quality during the actual kneading process; for this reason, after kneading the dough, the staff will increase the conveying distance of the conveyor belt to improve the kneading effect of the dough, and the dough is conveyed between the two conveyor belts by the synchronous movement of the conveyor belts. This conveying method cannot adjust the distance between the two conveyor belts and the inclination angle of the conveyor belts according to the consistency of the dough, which leads to unsatisfactory conveying effect of the dough;

[0007] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Summary of the invention

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0044] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0045] Reference Figure 1 , Figure 2 and Figure 3 , which is the first embodiment of the present invention, provides a dividing and forming device for producing hamburger buns. When the dividing and forming device is in use, the kneaded dough enters through the feeding mechanism 200, and the feeding mechanism 200 then transports the dough to the forming mechanism 100 for cutting into small doughs of a certain amount.

[0046] Specifically, it includes a forming mechanism 100, including an adjusting column 101, a linkage disk 102 symmetrically arranged at both ends of the adjusting column 101, and a cutter 103 arranged on the outer wall of one side of the adjusting column 101 along the axial direction of the adjusting column 101, and the cutter 103 is used for quantitative cutting of the extruded dough; a feeding mechanism 200, including a conveying box 201 and an extrusion plate 202 arranged inside the conveying box 201; and an operating table 300 arranged below the forming mechanism 100 and the feeding mechanism 200, and the feeding mechanism 200 and the cutter 103 are respectively arranged on both sides of the adjusting column 101.

[0047] See Figure 8 and Fig. 9As shown, one end of the conveying box 201 is configured to be a circular arc surface 201c that fits the outer wall of the adjusting column 101 to achieve a tighter fit between them, and at the same time, the other end of the conveying box 201 is fixed with a rear cover plate 201b by fixing bolts, so as to facilitate the disassembly and installation of the rear cover plate 201b, a cylinder 202a is fixedly sleeved in the middle of the rear cover plate 201b, and one end of the cylinder 202a is fixedly connected to the extrusion plate 202, and the circular arc surface 201c is provided with a plurality of feeding holes 201c-1 in an array along the axial direction of the adjusting column 101, which is equal to the number of a group of through grooves 101a, and the plurality of feeding holes 201c-1 are arranged in a one-to-one correspondence with the plurality of through grooves 101a in the group of through grooves 101a, and a feeding hopper 201a connected to the inside of the conveying box 201 is fixedly provided on the top surface of the conveying box 201 away from the adjusting column 101, and the feeding hopper 201a is convenient for adding dough into the conveying box 201;

[0048] When the above arrangement is in use, the dough added to the feed hopper 201a can be fed into the through groove 101a through the feed hole 201c-1 under the action of the extension of the cylinder 202a to drive the extrusion plate 202 to move, thereby facilitating the subsequent cutting operation.

[0049] Furthermore, T-shaped rods 202b are symmetrically fixed on the extrusion plates 202 on both sides of the cylinder 202a, and the T-shaped rods 202b are slidably sleeved on the rear cover plate 201b. This arrangement can play a role in limiting and guiding the movement of the extrusion plates 202.

[0050] See Figure 4 , Figure 5 and Figure 6 As shown, a through groove 101a is opened on the side wall of the adjusting column 101 along the radial direction, and a plurality of through grooves 101a opened in an array along the axial direction of the adjusting column 101 are formed as a group. Then, n groups of through grooves 101a are opened on the side wall of the adjusting column 101 along the circumferential array, and the diameters of the through grooves 101a uniformly distributed along the circumference of the adjusting column 101 are different, so that the thickness of the extruded dough can be adjusted. A conveying sleeve 104 is slidably sleeved in any group of the n groups of through grooves 101a, and the conveying sleeve 104 is used for conveying the dough. The different diameters of the through grooves 101a in each group can adjust the thickness of the extruded dough as needed under the action of rotating the adjusting column 101.

[0051] Furthermore, the conveying sleeve 104 is composed of two symmetrical semicircular sleeves. The arrangement of the semicircular sleeves makes it convenient for the staff to clean the inside of the conveying sleeve 104. Matching pieces 104a are symmetrically fixed in the middle of the two ends of the outer wall of the semicircular sleeve. At the same time, a matching groove 101a-1 for gap matching with the matching piece 104a is opened on the inner wall of the through groove 101a; the cross-section of the matching piece 104a is an isosceles triangle, one of the waist edges is fixedly connected to the outer wall of the conveying sleeve 104, and the base of the isosceles triangle is an arc shape that is congruent with the outer wall of the adjusting column 101. The end face of the conveying sleeve 104 has the same shape as the end face of the through groove 101a. This arrangement can, on the one hand, allow the conveying sleeve 104 to be fixed in the through groove 101a, and also facilitate the removal of the conveying sleeve 104 after the combination block 101c is unfolded.

[0052] See Figure 5 and Figure 6 As shown, the adjusting column 101 is divided along the center position of the same group of through grooves 101a, so as to divide the entire adjusting column 101 into n combination blocks 101c arranged in a circumferential array, and connecting pieces 101b-1 are symmetrically fixed on both end surfaces of the combination block 101c, and a telescopic column 101b extending toward the center position of the adjusting column 101 along the radial direction of the adjusting column 101 is fixed on one side surface of the connecting piece 101b-1, and a circular arc piece 101b-3 is fixed on the free end of the telescopic column 101b, and a magnetic piece 101b-4 is fixed on the side surface of the circular arc piece 101b-3 away from the telescopic column 101b, and the telescopic column 101b is slidably sleeved on the side wall of the linkage disk 102, and the telescopic column 101b located on the inner side of the linkage disk 102 slides on the telescopic column 101b A spring 101b-2 is sleeved, and the setting of the spring 101b-2 facilitates the automatic reset of the telescopic column 101b; a first rotating column 102b is fixedly provided in the middle of one end surface of the linkage disk 102 away from the adjusting column 101, and an electromagnetic ring 102a is slidably sleeved on the first rotating column 102b at the position of the magnetic piece 101b-4, and the electromagnetic ring 102a is fixedly connected to the end surface of the linkage disk 102, and the side surfaces close to the electromagnetic ring 102a and the magnetic piece 101b-4 are arranged in the same sex, and the first rotating column 102b is rotatably connected to the first support plate 301 fixed on the top surface of the operating table 300 through a rolling bearing, so as to realize the rotation of the adjusting column 101 with the first rotating column 102b as the axis, so as to facilitate the switching adjustment between each group of through slots 101a;

[0053] When the above arrangement is in use, magnetism can be generated when the electromagnetic ring 102a is energized. Under the effect of like charges repelling each other, multiple telescopic columns 101b drive n combination blocks 101c to expand outward synchronously, thereby making it convenient for staff to take and place the conveying sleeve 104. When the electromagnetic ring 102a is powered off, the n combination blocks 101c can be aggregated into a columnar shape under the effect of the spring 101b-2 resetting.

[0054] Furthermore, a polymer sleeve 102c is slidably sleeved on the first rotating column 102b. When the n combination blocks 101c are gathered into a columnar shape, the inner wall of the polymer sleeve 102c fits with the outer wall of the arc piece 101b-3. The setting of the polymer sleeve 102c can further limit and fix the arc piece 101b-3 after the n combination blocks 101c are gathered together. The lower end of the side wall of the polymer sleeve 102c is symmetrically fixed with a fixing ear 102c-1, and the fixing ear 102c-1 is fixed to the first support plate 301 by a fixing bolt. This setting can disassemble the polymer sleeve 102c to realize whether the polymer sleeve 102c is matched with the arc piece 101b-3. Example 2

[0055] Reference Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, except that this embodiment is proposed to facilitate the precise switching between the groups of through slots 101a and the limiting fixation of the adjustment column 101 after the switching.

[0056] Specifically, a positioning plate 102d is provided at one end of the adjusting column 101, and a polygonal block 102d-1 is fixedly provided at the upper position of one side surface of the positioning plate 102d, and positioning holes 102d-2 are symmetrically provided at the lower end of the positioning plate 102d, and a polygonal groove 102b-1 for clearance fitting with the polygonal block 102d-1 is provided on the free end of one of the first rotating columns 102b; the positioning plate 102d and one of the first support plates 301 are fixed by a locking bolt 102d-3, and a positioning column 301a for clearance fitting with the positioning hole 102d-2 is fixed on the first support plate 301, and this arrangement can further limit the cooperation between the first support plate 301 and the positioning plate 102d.

[0057] When the above arrangement is in use, when the staff needs to adjust the adjustment column 101, the staff loosens the locking bolt 102d-3 by a tool to separate the polygonal block 102d-1 and the polygonal groove 102b-1. After the separation is completed, the staff adjusts the position of the through groove 101a as needed. After the adjustment is completed, the staff fits the polygonal block 102d-1 into the polygonal groove 102b-1 and then limits the position by the locking bolt 102d-3.

[0058] In addition, it should be noted that the number of sides of the polygonal block 102d-1 and the polygonal groove 102b-1 is equal, and the number of sides is n. Example 3

[0059] Reference Figure 7, which is the third embodiment of the present invention, is based on the previous embodiment, except that, in order to facilitate the implementation of the present device, a specific description is given of the structure for cutting the dough after extrusion, see this embodiment for details.

[0060] Specifically, one end of the cutter 103 is also fixedly connected to one end of the linkage plate 103a through a connecting rod 103a-1, and the other end of the linkage plate 103a is rotatably connected to the second rotating column 103b-1 through a rolling bearing, and one end of the second rotating column 103b-1 is fixedly connected to one side surface of the second support plate 103b;
