Description

Technical Field

[0001] This invention relates to the field of biscuit packaging equipment technology, and more specifically to a propulsion and transfer mechanism that can efficiently transfer biscuits from one device to another. Background Technology

[0002] In existing technology, biscuit production line equipment produces multiple rows of flat biscuits through processes such as forming, baking, and cooling. These biscuits are then sorted by a biscuit sorting machine, filled, and packaged. During biscuit production, different equipment is needed for each step, requiring transfer mechanisms between them. However, existing transfer mechanisms, in order to achieve smooth transfers and low breakage rates, often sacrifice clearance and operating speed, resulting in large clearances and slow transfer speeds. Summary of the Invention

[0003] The purpose of this invention is to provide a compact, easy-to-use, and highly efficient biscuit transfer mechanism to overcome the shortcomings of existing technologies.

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

[0005] A biscuit pushing and transferring mechanism includes: a front device, a rear device, and a tray connecting the front device and the rear device. The front device has a plurality of continuously rotating first push rods, and the rear device has a plurality of continuously rotating second push rods. Each first push rod pushes a biscuit along the tray from the upper side of the tray. The tray has a slit, and each second push rod pushes the biscuit upward through the slit from the lower side of the tray. Each second push rod is connected to a continuous conveying mechanism of the rear device via a rotating shaft, allowing each second push rod to rotate at a certain angle. Each second push rod also has a push rod guide rod. The rear device has a push rod guide rail corresponding to the front device, which cooperates with the push rod guide rods to drive each second push rod to fold and rotate along a trajectory defined by the push rod guide rail.

[0006] Preferably, the second push rod has a push rod bar and a push rod seat, the push rod bar being fixed on the push rod seat for pushing the biscuit; the push rod seat has a pivot mounting hole and a locking hole, the locking hole being intersecting and communicating with the pivot mounting hole; a locking ball, a spring, and a locking block are placed in the locking hole, the spring being located between the locking ball and the locking block to provide a preload force to the locking ball and to cause the locking ball to protrude a small semicircle within the pivot mounting hole; an annular groove that mates with the locking ball is provided on the pivot.

[0007] Preferably, the push rod bar is located on the upper side of the push rod seat and is perpendicular to the push rod seat, the rotating shaft mounting hole and the push rod guide rod are located on the left and / or right side of the push rod seat, and the locking hole is located on the front or rear side of the push rod seat.

[0008] Preferably, the locking hole is a threaded hole, and the locking block is a bolt.

[0009] Preferably, the locking ball is a rigid sphere.

[0010] Preferably, the push rod guide rail is provided with a front guide rail groove, a middle section rail and a rear section rail connected in sequence. The push rod guide rod rotates upward along the rotating axis by an acute angle under the guidance of the middle section rail and returns to the plane where the continuous conveying mechanism is located under the guidance of the rear section rail.

[0011] Preferably, the front guide rail groove is a wide opening that flares outwards.

[0012] The beneficial effects of this invention are as follows: By setting the second push rod as a rotating mounting structure and combining it with the push rod guide rail structure located between the front and rear equipment, the push rod has the maximum thrust component and the optimal contact angle when receiving material from the front equipment, thus better protecting the biscuit from breakage. Moreover, the staggered arrangement of the first and second push rods results in a compact structure that is easy to use, minimizing the space occupied between the push rods on the front equipment chain and the time required, thereby achieving higher efficiency.

Detailed Implementation

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] like Figure 1 As shown, a biscuit propulsion and transfer mechanism includes: a front device, a rear device, and a tray 9 connecting the front device and the rear device. The front device has a plurality of continuously rotating front push rods 10, and the rear device has a plurality of continuously rotating push rods 2. Each front push rod 10 and each push rod 2 is used to push the biscuit along the tray 9. The front push rods 10 rotate under the drive of a sprocket 16, and the push rods 2 rotate under the drive of sprockets 5, 7, and 11. A push rod front support bar 6 is provided between sprockets 5 and 7, and a push rod upper pressure bar 8 is provided between sprockets 7 and 11, respectively, to maintain the push rods 2 at a predetermined angle. The push rods 2 of the front device and the push rods 2 of the rear device are initially located on the upper and lower sides of the tray 9, respectively.

[0022] When chain 1 drives push rod 2 to push rod guide plate 4, push rod guide rod 2d, under the action of the guide rail, causes push rod 2 to no longer be at a 90-degree angle with chain 1, but to stand upright at an acute angle and continue to advance along the track. At this time, the front equipment push rod 10 pushes the biscuit 3 supported on the pallet 9 to the predetermined position. The pallet 9 has a gap in the center position. The rear equipment push rod 2 passes through the gap under the pallet 9 and pushes the biscuit upward. At this time, the biscuit is completely pushed forward by the rear equipment push rod 2, which completely takes over the biscuit conveying task. After leaving the push rod guide plate 4, the rear equipment push rod 2 returns to the position at a 90-degree angle with the chain and continues to advance, carrying the biscuit for post-processing.

[0023] It should be noted that in this embodiment, chain 1 mainly serves as a continuous conveyor, carrying push rod 2 in a cyclical motion. Obviously, depending on the needs, other continuous conveying mechanisms such as conveyor belts can be used to replace chain 1.

[0024] like Figure 2 , Figure 3As shown, the push rod 2 has a push rod bar 2a, a push rod seat 2b, a push rod guide rod 2d, and a shaft mounting hole 2e. The push rod seat 2b has a threaded hole that intersects and communicates with the shaft mounting hole 2e, preferably at a 90° angle. A locking steel ball 15 is placed in the threaded hole, and then a spring 14 is inserted and screwed into the threaded hole with a countersunk screw 13 to apply preload to the spring 14. The steel ball 15 is pressed into the threaded hole of the push rod seat 2b and protrudes a small semicircle into the shaft mounting hole 2e. The shaft mounting hole 2e is subsequently used in conjunction with the shaft 12 on the chain 1.

[0025] It should be noted that the threaded hole is only for easy locking, and the locking steel ball 15 and spring 14 are only provided to enable the push rod 2 to be axially fixed and radially rotated along the axis of rotation. Obviously, those skilled in the art can use locking holes of other structures and then replace them with corresponding locking blocks by bolts; for example, the cooperation of two snap-fit ​​holes can achieve a similar locking effect; other forms of axial fixing and radial rotation connection structures can also be used to replace the combination structure of locking steel ball 15 and spring 14. In addition, it should be noted that the steel ball 15 is not limited to steel; other rigid spheres such as copper, iron, and ceramic can also be used to replace the steel ball to achieve a similar technical effect.

[0026] like Figure 4 , Figure 5 As shown, several adjacent rotating shafts 12a and 12b are spaced apart on the chain 1. Each adjacent rotating shaft has a semi-circular annular groove 12c machined on it. The push rod 2 is inserted into the rotating shaft 12a through the push rod seat 2b. When it is first inserted, the shaft head pushes the steel ball into the compression spring 14, causing the shaft head to continue to move inward. When the annular groove 12c just reaches the position of the steel ball 15, the steel ball 15 is ejected under the action of the spring 14, and just locks the annular groove 12c, thus fixing the push rod 2 in the axial position. The push rod 2 can only rotate and cannot move axially. In the direction of rotation, due to the restriction of the rotating shaft 12b, the push rod 2 can only rotate a limited angle of about a°.

[0027] It should be noted that the rotating shaft 12 and the push rod guide rod 2d can be set on one side of the push rod seat 2b or on both sides; it is not limited to the example in the attached figure.

[0028] like Figure 6 As shown, the push rod guide rail 4 is provided with a guide rail groove. The front section of the guide rail groove 4a has a wide opening, allowing the push rod 2 guide rod 2d to smoothly enter the track. The push rod continues to run, and the push rod guide rod 2d rotates clockwise by an acute angle c along the axis of rotation under the guidance of the track 4b, so that the push rod 2 is in a semi-erect state and continues to move forward. An obtuse angle b is formed between the track 4c and the track 4b. After the push rod 2 reaches the track 4c, it returns to being perpendicular to the chain 1. Then, the push rod is supported by the push rod support surface 2c by the rear support bar 17 and moves forward stably.

[0029] Obviously, the number of track segments of the push rod guide rail 4 is not limited to the three-segment structure mentioned above. As long as the track setting can achieve the following: make the push rod 2 rotate upward by an acute angle and return to the plane where the continuous conveying mechanism is located during subsequent operation.

[0030] The biscuit propulsion and transfer mechanism provided in this embodiment works as follows: A push rod 2 assembly with fixed intervals is installed on the chain 1 according to usage requirements. The chain 1 first moves to the sprocket 11. At this time, the push rod support surface 2c on the push rod assembly enters the upper pressure bar 8. Under the action of the upper pressure bar 8, it stably reaches the sprocket 7 located to the lower left of the sprocket 16 of the preceding equipment, and then moves upward. At this time, the direction of travel of the chain 1 forms an acute angle d with the direction of travel of the push rod 10 of the preceding equipment. Supported by the push rod front support bar 6, the push rod 2 enters the push rod guide plate 4. When passing through section 4b of the track, the push rod 2 flips up at angle c, so that the push rod 2 obtains a maximum force angle in the rightward direction of travel, obtaining the maximum forward component force, so that the push rod has a more stable pushing force direction to push the biscuit forward. At the turning position of track 4b and track 4c of the push rod guide plate 4, the push rod 2 completely takes over the propulsion work of the push rod 10 of the preceding equipment, continuing to push the biscuit forward and perform subsequent processing.

[0031] Based on the above description of the structure and principles, those skilled in the art should understand that this invention is not limited to the specific embodiments described above. Improvements and substitutions made using techniques known in the art based on this invention all fall within the scope of protection of this invention, which should be defined by the claims and their equivalents. Parts not described in the specific embodiments are all prior art or common knowledge.
