Description

Technical Field

[0001] The invention relates to the field of vacuum sealing technology, and in particular to a sauerkraut packaging vacuum sealing device with an auxiliary shaping function. Background Art

[0002] Sauerkraut can be an appetizer, a side dish, or a seasoning for dishes. It can be divided into Northeastern sauerkraut, Sichuan sauerkraut, Guizhou sauerkraut, Yunnan Fuyuan sauerkraut, German sauerkraut, etc. The taste and style of sauerkraut in different regions are also different. The "sauerkraut" that ordinary people often refer to generally refers to all kinds of sauerkraut made from green vegetables or cabbage. When sauerkraut is mass-produced and sold, it can be vacuum-packed to increase the shelf life, and vacuum sealing equipment is needed.

[0003] However, there are still some problems when using the existing sauerkraut packaging vacuum sealing equipment:

[0004] There is a vacuum sealing device for pickled cabbage buns in China with patent application number CN201821614463.7, which includes a vacuum sealer, a control console, a sealing assembly, a support rod, a bearing, a rubber block, a support plate, a groove, a main shaft, a movable plate, a buckle, an extension plate groove, a hinge and an extension plate. The top of the vacuum sealer is integrally connected with the control console, the front side wall of the control console is fixed with a sealing assembly by bolts, the top of the support rod is bonded with a rubber block, the front side wall of the vacuum sealer is welded with a bearing, the rear side wall of the support plate is rotatably connected to the vacuum sealer through a bearing, and a groove is provided on the rear side of the top of the support plate;

[0005] However, the existing sauerkraut vacuum sealing device cannot shape or restrict the deformation of the sauerkraut during use, resulting in different overall shapes of the sauerkraut packages after vacuum packaging, which not only has a poor appearance, but also can only be piled up during subsequent storage, and cannot be neatly stacked;

[0006] The existing sauerkraut vacuum sealing device cannot perform continuous operation and has simple overall operation, but is only suitable for vacuum sealing operations of a small amount of sauerkraut. If the amount of sauerkraut is large, the vacuum sealing efficiency of the existing device is low and the manual labor is large.

[0007] In view of the above problems, an innovative design was carried out based on the original sauerkraut packaging vacuum sealing equipment with auxiliary shaping function. Summary of the invention

[0008] The purpose of the present invention is to provide a sauerkraut packaging vacuum sealing device with an auxiliary shaping function to solve the problems mentioned in the above background technology that the existing sauerkraut sealing equipment is not convenient for continuous operation when used, and the sauerkraut packages after sealing have different shapes, which is not convenient for stacking and storage.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a vacuum sealing device for sauerkraut packaging with auxiliary shaping function, comprising a supporting frame:

[0010] A conveyor belt is installed in the middle of the support frame, and a support platform is provided at the upper right end of the conveyor belt. Positioning sleeves are fixed on both sides of the right end of the support frame, and support rods are embedded in the positioning sleeves. The upper end of the support rod is connected to the support platform.

[0011] A clamping and positioning plate is provided at the lower end of the support platform, and two groups of the clamping and positioning plates are symmetrically arranged front and back. The heating and sealing modules are clamped and installed at the lower ends of the two groups of clamping and positioning plates on opposite sides. Sealing strips are provided on the opposite sides of the two groups of clamping and positioning plates. Support plates are fixed to the lower ends of both sides of the support platform, and a threaded screw rod penetrates the middle of the support plate. A transmission sleeve is fixed to the middle of the clamping and positioning plate, and the threaded screw rod extends to the inside of the transmission sleeve.

[0012] A guide square tube is fixed at the upper middle end of the support platform, and an air intake pipe is provided at the lower end of the guide square tube penetrating the support platform, a sealing tube is provided at the rear side of the support platform, a piston is provided inside the sealing tube, and a guide tube is connected between the end of the sealing tube away from the piston and the guide square tube;

[0013] A shaping plate is arranged at the lower end of the clamping positioning plate, and transmission plates are connected to the upper ends of both sides of the shaping plate. A transmission groove is opened inside the transmission plate, and a second transmission shaft is embedded in the transmission groove, and the second transmission shaft is fixed to the support rod.

[0014] Preferably, limiting grooves are provided on opposite sides of the two groups of clamping and positioning plates, and the limiting grooves are adapted to the shape of the suction pipe. A guide plate is connected to the lower end of the clamping and positioning plate, and the guide plate is tilted, forming an "eight" shape between the two groups of guide plates.

[0015] By adopting the above technical solution, the upper end of the packaging bag can be clamped by two sets of clamping and positioning plates, and the limiting groove can be used to engage the suction pipe to keep the upper end of the packaging bag connected only to the suction pipe, ensuring that the suction pipe can suck the gas inside the packaging bag. The design of the two sets of guide plates can guide the packaging bag to move toward the middle of the two sets of clamping and positioning plates, ensuring reliable clamping.

[0016] Preferably, the threaded screw is rotatably connected to the support plate, and the inner end of the threaded screw is threadedly connected to the transmission sleeve, the support plate and the threaded screw are symmetrically distributed front and back, and the thread directions of the two groups of threaded screws are opposite;

[0017] The two ends of the support plate pass through the limiting sliding rods, and the support plate is slidably connected to the limiting sliding rod, and the inner side end of the limiting sliding rod is fixedly connected to the clamping positioning plate.

[0018] By adopting the above technical solution, the relative positions of the two sets of clamping positioning plates can be adjusted through the cooperation of the threaded screw and the transmission sleeve. The two sets of threaded screws with opposite thread designs ensure that the two sets of clamping positioning plates move in relative directions synchronously to complete the clamping and releasing actions. When the clamping positioning plates move, the cooperation of the limit slide rod and the support plate can improve the stability during horizontal movement.

[0019] Preferably, the lower end of the guide square tube is connected to an air inlet check valve, and the upper end of the air intake pipe is conductively connected to the air inlet check valve, the air intake pipe, the air intake check valve and the limit grooves are distributed in an equidistant array, the upper end of the sealing tube away from the piston is connected to an air outlet check valve, and the upper end of the air outlet check valve is connected to an air outlet hood.

[0020] By adopting the above technical scheme, through the design of the air inlet check valve and the air outlet check valve, it is ensured that when the piston moves inside the sealing tube, air can be smoothly sucked in through the air suction pipe and air can be discharged through the air outlet check valve, thereby controlling the direction of the air flow and ensuring that the air inside the packaging bag can be sucked, thereby vacuum packaging the sauerkraut. The upper end of the air outlet check valve is connected to the air outlet hood to prevent debris from entering the inside of the sealing tube.

[0021] Preferably, the piston is slidably connected to the sealing tube, the end of the piston away from the guide tube is rotatably connected to a transmission connecting rod, the end of the transmission connecting rod away from the piston is rotatably connected to the first transmission shaft, a power motor is fixed to the upper end of the support platform close to the first transmission shaft, and a cam is connected to the end of the power motor close to the first transmission shaft, the cam is fixed to the first transmission shaft, and the first transmission shaft and the cam are connected offset from the axis of the power motor.

[0022] By adopting the above technical solution, the cam can be driven to rotate by the power motor, and the cam can be used to drive the first transmission shaft to perform circular motion around the axis of the power motor, and the first transmission shaft can be used to drive the transmission connecting rod and the piston to reciprocate left and right, thereby providing power for the vacuum extraction of the sauerkraut packaging bag.

[0023] Preferably, a fixing plate is fixed by bolts on both sides of the right end of the support frame, and an electric push rod is fixed to the outer side of the upper end of the fixing plate. The electric push rod passes through the fixing plate and is fixedly connected to the shaping plate. Grooves are opened on both sides of the upper end of the right side of the support frame, and the grooves are adapted to the shaping plate.

[0024] By adopting the above technical solution, the electric push rod can push the two sets of shaping plates to move in relative directions, which is convenient for extruding and shaping the sauerkraut, ensuring that the sauerkraut has a uniform shape after vacuum packaging, thereby improving the aesthetics and product appearance.

[0025] Preferably, the upper end of the shaping plate is designed as an inverted "U" shaped structure, and the upper ends of both sides of the shaping plate are fixed to the transmission plate, the transmission groove is designed to be inclined, and the transmission groove is slidingly connected to the second transmission shaft, and transmission racks are fixed on the opposite sides of the two groups of fixed plates, and the outer end of the threaded screw is connected to a transmission gear, and the transmission gear is meshingly connected to the transmission rack.

[0026] By adopting the above technical scheme, the shaping plate can simultaneously drive the transmission plate to move when shaping the sauerkraut package, thereby changing the position of the transmission groove. Due to the inclined design of the transmission groove, the second transmission shaft, the support rod and the support platform can be pushed up and down after the position is moved. When the support platform descends, the transmission gear and the transmission rack can be controlled to engage, thereby controlling the rotation of the threaded screw. The threaded screw is used to control the two sets of clamping and positioning plates to clamp and position the upper end of the packaging bag synchronously.

[0027] Preferably, the conveyor belt is externally connected with a limit baffle, and the limit baffles are distributed in an equidistant array outside the conveyor belt, and the distance between two adjacent groups of limit baffles is the same as the left and right length of the shaping plate.

[0028] By adopting the above technical solution, the outside of the transmission belt is divided into multiple areas through the design of multiple sets of limit baffles, which makes it easier to locate the position of a single sauerkraut package during vacuum packaging operations and avoid offset during sealing.

[0029] Preferably, a movable groove is provided at the upper end of the limit baffle, and a positioning shaft is fixed inside the movable groove, a limit strip is provided between two adjacent groups of the limit baffles, and movable connecting rods are slidably connected at both ends of the limit strip, and both groups of movable connecting rods are slidably connected to the positioning shaft;

[0030] A return spring is fixed on the inner wall of the limit strip, and the movable connecting rod is fixedly connected to the return spring. A clamping groove is opened on the opposite side of the shaping plate, and the clamping groove matches the limit strip.

[0031] By adopting the above technical solution, through the cooperation of the limit baffle and the limit strip, the sauerkraut package can be protected and shielded on all four sides when it is placed on the transmission belt to avoid tipping over, thereby ensuring that the subsequent vacuum sealing operation can be carried out normally. At the same time, the cooperation of structures such as the movable connecting rod, the return spring and the positioning shaft can ensure that the normal rotation of the conveyor belt will not be restricted.

[0032] Compared with the prior art, the beneficial effects of the present invention are: the sauerkraut packaging vacuum sealing equipment with auxiliary shaping function, by providing a shaping structure, utilizes the cooperation of two sets of shaping plates to extrude and shape the sauerkraut packaging bag before vacuum sealing, thereby ensuring the uniform shape of the sauerkraut after vacuum sealing and improving the appearance of the goods. At the same time, the sauerkraut packaging with uniform shape is also convenient for subsequent storage, stacking and measurement.

[0033] 1. The transmission structure can control the lifting and lowering of the vacuum structure and the clamping structure to clamp and seal the upper end of the packaging bag while shaping the sauerkraut packaging, and then evacuate the air. The simple structure is used for linkage control to improve the convenience of operation and work efficiency.

[0034] 2. By setting a limiting structure on the outside of the conveyor belt, the stability of the sauerkraut when it is continuously loaded on the conveyor belt can be ensured, and it can be kept in an upright state to avoid tipping over during transportation, thereby improving the stability of subsequent vacuum sealing.
