Description

Technical Field

[0001] The invention relates to a cherry packaging device and a use method, belonging to the technical field of fruit packaging devices, and in particular to a device for cherry packaging. Background Art

[0002] Cherry is a kind of fruit that is very popular with the public. The fruit is irregularly spherical with a stalk. Its skin is thin and easy to break. Once the skin is damaged, it is easy to rot, so it is not convenient to transport. In order to improve the transportation capacity of cherries, how to reduce the loss of some high-quality cherries is a problem that technicians in this field have been studying. In the existing cherry packaging method, there are multiple positioning grooves made on the PVC board and the cherries are placed in them. This packaging method can solve the problem of cherries colliding with each other during transportation. However, since the cherry stalk is not protected, the cherry stalk is easy to fall off during transportation or puncture the cherry due to the force; the situation of covering it is also not conducive to the transportation of cherries. Therefore, how to ensure the integrity of cherries, especially high-quality large cherries during transportation, has become a topic of research for technicians in this field. Summary of the invention

[0003] In view of the problem that cherry packaging needs to ensure that the cherry stems are not easy to fall off or puncture the cherries during transportation, a cherry packaging device is provided.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A cherry packaging device comprises a frame, wherein the frame is provided with a thermoplastic forming module, a heat sealing and cutting device, a transverse conveying device, a conveyor belt module and a set module;

[0006] The thermoplastic forming module comprises an inflatable limit plate, a central hole is arranged on the plate surface of the inflatable limit plate, an inflatable seat is installed in the central hole, a gap is left between the periphery of the inflatable seat and the inner wall of the central hole of the inflatable limit plate, and an inflatable hole is arranged on the inflatable seat; the inflatable hole is connected to the inflatable pump through a pipeline; a barrel-shaped film forming shell is installed at the end of the inflatable seat; a heat sealing device is installed below the film forming shell; and an active roller is installed on the discharge side of the film forming shell;

[0007] A transverse conveying device is installed on the discharge side of the active roller; the transverse conveying device includes an L-shaped seat plate, two slide bars and a lead screw are installed under the bottom plate of the seat plate, and the lead screw is connected to the base through an internal thread slider; the end of the lead screw is connected to the motor; four support rods are installed on the vertical plate of the seat plate;

[0008] A packaging bag folding mechanism is installed above the horizontal conveying device; the packaging bag folding mechanism includes a low-pressure adsorption group, a sliding seat A is hingedly installed on the top of one end of the low-pressure adsorption group, and a sliding seat B is hingedly installed on the side of the other end of the low-pressure adsorption group, and the sliding seat B is connected to the lifting screw through a lifting slider; the sliding seat A is slidably installed on the top horizontal slide; the sliding seat B is slidably installed on the longitudinal slide parallel to the lifting screw.

[0009] The advantages of the above technical solution are: the equipment of the present application, by inserting the end of the rolled single-layer plastic film into the "gap left between the inflatable periphery and the inner wall of the middle hole of the inflatable limiting plate" of the thermoplastic forming module, the plastic film is surrounded by the outside of the inflatable seat and the film forming shell to form a barrel shape, and the combined ends on both sides of the plastic film are clamped in the heat sealing device for heat sealing; the formed plastic tube is heat-sealed at the end at the heat sealing cutting device, and at this time, air is continuously inflated in the inflatable seat. Under the action of wind force, the plastic tube continues to move forward, and while moving, the side heat-forming tube is realized. When the end of the plastic tube moves to the lateral transport After the plastic tube is delivered to the conveying device, the packaging bag folding mechanism adsorbs the end portion. The low-pressure adsorption group is first in a vertical state, and the internal thread block on the lifting screw moves upward, pushing the low-pressure adsorption group to a horizontal state, thereby realizing a 180° bend of the plastic tube. The bent end portion continues to move under the condition of continuous wind transmission until it moves to the heat sealing cutting device for heat sealing. At this time, after heat sealing, the plastic tube located at the horizontal conveying device is surrounded into an O-shaped air bag; finally, the O-shaped air bag is mounted on the cherry hole plate filled with cherries by the mounting module. This mounting method realizes the protection of the cherry handles.

[0010] On the basis of the above technical solution, this application makes the following improvements and perfections to the above technical solution:

[0011] Furthermore, the bottom of the film forming shell is fixedly supported by a support member, and the support member is also fixed on the inflatable limiting plate.

[0012] The beneficial effects of the above-mentioned technical features in the present application are: the film forming shell is supported by the support member to ensure that the film forming shell and the inflatable seat are located in the middle of the center hole of the inflatable limit plate. Such a structure can realize that the plastic film is surrounded by the outside of the film forming shell, which is convenient for forming a cylindrical shape; the support member can be made into a triangular shape, and such a structure is conducive to the fitting of the film.

[0013] Furthermore, the heat sealing device includes a heat sealing base plate, on which a heating block and a heat conducting block are relatively installed, two spliced ​​conveyor belts are clamped between the heating block and the heat conducting block, and the two ends of the spliced ​​conveyor belts are respectively mounted on the rotating wheel A and the rotating wheel B, and a pair of embossing wheels are installed at the discharge end of the heat sealing device.

[0014] The beneficial effect of the above technical features in the present application is that the butt-jointed sides of the plastic film are clamped between two heat-insulating conveyor belts and transported forward. During the forward transport process, when passing through the heating block and the fast heat conduction, the sides of the plastic are thermoplastically closed to form a cylindrical shape.

[0015] Furthermore, a pair of L-shaped guard plates are installed on both sides of the heat-sealed bottom plate.

[0016] The beneficial effect of the above-mentioned technical features in the present application is that the L-shaped guard plate can play a guiding and protective role.

[0018] The beneficial effects of the above-mentioned technical features in the present application are: the height of the two heat-sealing heating blocks is higher than the height of the cutter, and in the process of the upper clamping plate moving downward, the two heat-sealing heating blocks first pass through the gap on the lower clamping plate, first heat-seal the end of the cylindrical plastic tube, and then cut off during the process of continuing to press downward; that is, the thermoplasticization and cutting of the plastic film can be achieved by applying different pressures.

[0019] Furthermore, a pair of guide cylinders are arranged on the lower fixed plate, a guide rod matched with the guide cylinders is arranged on the lower clamping plate, and a spring is sleeved on the guide cylinders.

[0020] The beneficial effects of the above technical features in the present application are: the up and down movement of the lower clamping plate is achieved through the cooperation of the guide cylinder and the spring; the spring can effectively prevent the error caused by excessive cylinder pressure and vibration of the pressure plate on the workbench.

[0021] Further, the conveyor belt module includes a conveyor belt, a feed roller installed on the feed side of the conveyor belt, and a baffle installed on the other side of the conveyor belt.

[0022] The beneficial effect of the above technical features in the present application is that the O-shaped inflatable bag is transported to the suit module via a conveyor belt.

[0023] Furthermore, an inclined unloading plate is installed at the unloading end of the conveyor belt.

[0024] Furthermore, the set module includes a sliding seat plate, which is installed on the sliding rail through a slider, and a U-shaped mounting plate is installed on the sliding seat plate, a row of lower supporting clamps are installed in the U-shaped mounting plate, and an electromagnetic push rod is installed on each side plate on both sides of the U-shaped mounting plate. The piston rod end of the electromagnetic push rod is hingedly installed with a pull rod, and the ends of the pull rods on both sides are respectively hinged to the two ends of the upper clamp cross bar, and the upper clamp is installed on the upper clamp cross bar.

[0025] The beneficial effects of the above-mentioned technical features in the present application are: the extension and retraction of the electromagnetic push rods on both sides, through the hinged pull rod transmission, can realize the lifting and lowering of the upper clamping plate cross bar, and then realize the opening and closing between the upper clamping plate and the lower clamping plate, and the cherry hole plate filled with cherries can be clamped between the upper clamping plate and the lower clamping plate, so that the O-shaped air bag can be put on the upper clamping plate and the lower clamping plate, and the upper and lower clamping plates can be pulled out by sliding the sliding seat plate to complete the packaging of the cherries.

[0026] This application also designs the use of the equipment that complies with this application:

[0027] A method for using a cherry packaging device, characterized in that the O-shaped inflatable sleeve processed by the cherry packaging device described in any of the above schemes is used to insert the cherries into a cherry hole plate, the cherry handles stand on the cherry hole plate, and the O-shaped inflatable sleeve is put on the outside of the cherry hole plate.

[0028] According to the average size and diameter of cherries, we finally decided to use XJ-grade cherries with a diameter of 28mm-30mm as our cherry model. According to the statistical algorithm, we counted the weight of 100 JJ-grade cherries and finally determined that the average weight of JJ-grade cherries fluctuates around 8.0g. Therefore, we designed the corresponding food-grade PVC board and pearl cotton foam board as the packaging carrier for cherries. BRIEF DESCRIPTION OF THE DRAWINGS
