Description

Technical Field

[0001] This utility model relates to the field of freeze-drying technology, and in particular to a cutting device for freeze-drying production. Background Technology

[0002] Pet freeze-drying, also known as vacuum freeze-drying, works by rapidly freezing pet food containing moisture, such as chicken breast, beef, and vegetables, in a low-temperature vacuum environment. This causes the ice to sublimate directly into water vapor, removing the moisture from the food and thus drying the material. After freeze-drying, pet food is bulky and difficult to package, so it needs further processing to be cut into pieces. However, current cutting devices have low processing efficiency.

[0003] For example, a fruit and vegetable cutting device for freeze-drying production disclosed in Chinese patent literature (publication number: CN222038664U) uses a fixed plate and a clamping mechanism to place the freeze-dried fruit and vegetables on the fixed plate. Turning the rotary switch counterclockwise drives the gear to rotate counterclockwise, which in turn drives the first L-shaped rod and the second L-shaped rod to move towards the center. The first L-shaped rod and the second L-shaped rod drive the first clamping block and the second clamping block to move towards the center, thus clamping the freeze-dried fruit and vegetables and improving work efficiency.

[0004] However, when using a fixed plate to clamp and cut freeze-dried food into blocks, the fixed plate needs to be loosened and removed after each cut, and the freeze-dried food to be cut needs to be placed in place before being fixed again. The whole process requires manual control of the clamping mechanism repeatedly, which makes the operation cumbersome and seriously affects the cutting efficiency. In addition, the freeze-dried food will produce debris during cutting, which can easily fall into the groove above the fixed plate and gradually accumulate around the gears and other transmission components, increasing the resistance of gear rotation and increasing equipment maintenance costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome and inefficient operation of cutting freeze-dried pet food, the easy absorption of debris during cutting, and the increased equipment maintenance costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cutting device for freeze-drying production includes a processing table, the processing table having a circulating feeding mechanism inside;

[0008] The circulating feeding mechanism includes a rotating rod. The lower end of the rotating rod is rotatably connected to the inner bottom wall of the processing table via a bearing. A worm gear is fixedly sleeved on the outside of the rotating rod. A through slot is provided above the processing table. The upper end of the rotating rod extends through to the top of the processing table and is fixedly connected to a connecting rod arranged in a ring array. A placement frame is fixedly connected to one end of the connecting rod. A sealing plate is hinged to one side of the placement frame via a hinge. The upper end of the sealing plate contacts the lower end of the placement frame, and the lower ends of two of the sealing plates contact the top of the processing table.

[0009] A slitting mechanism is installed above the processing table.

[0010] Preferably, a support block is fixedly connected to the inner top wall of the processing table, one end of the support block is hinged to a rubber roller via a pin, and a discharge pipe is fixedly connected to the lower end of the processing table.

[0011] Preferably, the upper end of the discharge pipe extends into the interior of the processing table and is fixedly connected to a collection hopper, and a servo motor is fixedly installed on the inner bottom wall of the processing table.

[0012] Preferably, the output shaft of the servo motor is fixedly mounted with a worm gear via a coupling, and the outer surface of the worm gear meshes with the tooth surface of the worm wheel.

[0013] Preferably, the slitting mechanism includes an L-shaped mounting plate, the lower end of which is fixedly connected to the upper end of the processing table, and a servo electric cylinder is fixedly mounted on the upper end of the L-shaped mounting plate. One end of the piston rod of the servo electric cylinder passes through the L-shaped mounting plate and is fixedly connected to a fixing plate.

[0014] Preferably, the upper end of the fixing plate is fixedly connected with symmetrically distributed guide rods, one end of each of the two guide rods passing through and extending above the L-shaped mounting plate, and a slot is provided on one side of the fixing plate, with a clearance groove provided on the inner bottom wall of the slot.

[0015] Preferably, a movable plate is movably inserted into the inner wall of the slot, a handle is fixedly connected to one side of the movable plate, and a cutter arranged in a linear array is fixedly connected to the lower end of the movable plate. The lower end of the cutter passes through the clearance groove and extends to the bottom of the fixed plate. A hand-tightening bolt is threadedly connected to the upper end of the fixed plate, and the lower end of the hand-tightening bolt contacts the upper end of the movable plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, a circulating feeding mechanism is used, which drives a servo motor to drive a worm gear, causing the placement frame to rotate 120 degrees each time, thus achieving cyclic rotation. While cutting, other placement frames can be fed. This not only avoids the need for repeated fixing and disassembly during freeze-drying and cutting, but also eliminates the need to stop the machine to wait for feeding, greatly improving the efficiency of freeze-drying and cutting, and enabling continuous production. It also prevents debris from flying everywhere during cutting, protecting the precision transmission components and reducing maintenance costs.

[0018] When the placement frame rotates into the through slot, the sealing plate automatically flips open due to the lack of support at the bottom. The slit freeze-dried food falls smoothly into the collection hopper and is collected through the discharge pipe, realizing automatic feeding. In addition, the servo electric cylinder in the slitting mechanism can precisely control the lifting and lowering of the fixed plate, movable plate and cutter, realizing effective slitting of the freeze-dried food in the placement frame. The design of the movable plate and the hand-tightening bolts makes it easy to replace cutters with different spacings and disassemble and maintain according to slitting needs, improving the convenience of operation.

[0029] Example

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a cutting device for freeze-drying production, including a processing table 1, a circulating feeding mechanism and a cutting mechanism. The processing table 1 serves as a basic support structure, supporting other components and providing working space; the circulating feeding mechanism is responsible for the circulating feeding, unloading and debris handling of freeze-dried products; the cutting mechanism enables precise cutting of freeze-dried products.

[0031] The lower end of the rotating rod 2 is rotatably connected to the inner bottom wall of the processing table 1 through a high-precision bearing to ensure that the rotating rod 2 can rotate flexibly. The worm gear 21 is fixedly sleeved on the outside of the rotating rod 2 through key connections and other means to realize power transmission.

[0032] A through slot 22 is provided above the processing table 1. The upper end of the rotating rod 2 extends through to the top of the processing table 1. Connecting rods 23 arranged in a ring array are fixedly connected to its exterior by welding or other means. One end of the connecting rod 23 is fixedly connected to the placement frame 24 by welding or other means, so that the rotating rod 2 can drive the placement frame 24 to rotate synchronously when it rotates.

[0033] One side of the placement frame 24 is hinged to the sealing plate 25. The upper end of the sealing plate 25 contacts the lower end of the placement frame 24, and the lower ends of two of the sealing plates 25 contact the upper part of the processing table 1 to prevent the freeze-dried fruits and vegetables from falling off during rotation.

[0034] The inner top wall of the processing table 1 is fixedly connected with a support block 26 by welding or other means. One end of the support block 26 is hinged to a rubber roller 27 by a pin. The rubber roller 27 can contact the sealing plate 25 when the placement frame 24 rotates, and assist the sealing plate 25 to flip and close.

[0035] The lower end of the processing table 1 is fixedly connected to the discharge pipe 28 by welding or other means. The upper end of the discharge pipe 28 extends into the interior of the processing table 1 and is fixedly connected to the collection hopper 29 by welding or other means, for collecting the freeze-dried product after slitting.

[0036] A servo motor 210 is installed on the inner bottom wall of the processing table 1 by means of screws or other means. The output shaft of the servo motor 210 is fixedly connected to the worm gear 211 through a coupling. The outer surface of the worm gear 211 is connected to the tooth surface of the worm wheel 21 through a precision meshing structure to achieve effective power transmission.

[0037] The lower end of the L-shaped mounting plate 3 is fixedly connected to the upper end of the processing table 1 by welding or bolting. The upper end of the L-shaped mounting plate 3 is fixed with screws. One end of the piston rod of the servo electric cylinder 31 passes through the L-shaped mounting plate 3 and is fixedly connected to the fixing plate 32 by welding or bolting.

[0038] The upper end of the fixing plate 32 is fixedly connected with symmetrically distributed guide rods 33 by welding or bolt connection. One end of each guide rod 33 passes through and extends to the top of the L-shaped mounting plate 3, providing precise guidance for the up and down movement of the fixing plate 32.

[0039] A slot 34 is machined on one side of the fixed plate 32. A clearance groove 35 is provided on the bottom wall of the slot 34. The inner wall of the slot 34 is connected to the movable plate 36 through a movable plug-in structure. A handle 37 is fixedly connected on one side of the movable plate 36 by welding or bolting to facilitate the insertion and removal of the movable plate 36.

[0040] The lower end of the movable plate 36 is fixedly connected to a linear array of cutters 38 by welding or bolting. The lower end of the cutters 38 passes through the clearance groove 35 and extends to the bottom of the fixed plate 32 for cutting freeze-dried fruits and vegetables. The upper end of the fixed plate 32 is fitted with a hand-tightening bolt 39 by threaded connection. The lower end of the hand-tightening bolt 39 contacts the upper end of the movable plate 36 to fix the position of the movable plate 36.

[0041] The working process of this utility model:

[0042] Step 1: Place the freeze-dried food to be cut into the placement frame 24. Start the servo motor 210, and its output shaft drives the worm gear 211 to rotate. The worm gear 211 meshes with the worm wheel 21, causing the rotating rod 2 to rotate. This drives the connecting rod 23 and the placement frame 24 to rotate 120 degrees each time, achieving cyclic rotation. When the placement frame 24 rotates to the bottom of the cutting mechanism, the servo electric cylinder 31 starts, and the piston rod extends, driving the fixed plate 32, the movable plate 36, and the cutter 38 to descend, cutting the freeze-dried food in the placement frame 24. During this process, the operator can continue to add freeze-dried food to other placement frames 24 that have rotated to the front. After the cutting is completed, the piston rod of the servo electric cylinder 31 retracts, driving the cutter 38 to rise and reset, and the placement frame 24 continues to rotate.

[0043] Step two: When the placement frame 24 rotates to the through slot 22, due to the lack of support at the bottom of the sealing plate 25, the sealing plate 25 flips open with the help of the hinge. The slit freeze-dried food falls into the collection hopper 29 and is collected through the discharge pipe 28. When the placement frame 24 rotates again, the rubber roller 27 contacts the sealing plate 25 and assists in squeezing the sealing plate 25, causing it to gradually flip and close. Finally, the sealing plate 25 is fully in contact with the placement frame 24 by the squeezing of the processing table 1 and rotates to the operator's face, making it convenient for the operator to add material again, thus completing a complete cycle.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
