[0009] On the basis of the above technical solution, the above technical solution is improved as follows in the present application:

[0010] Further, the apple posture adjusting mechanism comprises a stepping motor C and a roller row, the roller row is parallel to a plurality of rollers, the roller shafts of the rollers are fixedly installed on the single ear chains on the two sides, and a rubber plate is inserted into the center of the chain and in contact with the rollers above; the middle of the roller is concave; the stepping motor C is connected with the driving gear at the end of the chain through a shaft coupling.

[0011] The above technical features have the following beneficial effects in the present application:

[0012] The apple posture adjusting mechanism is an apple posture adjusting mechanism, which is mainly driven by a step motor C and a coupling to drive a chain to drive the rollers. When the apple is placed in the apple posture adjusting mechanism in any posture, the rollers on the single-ear chain self-rotate due to the friction of the rubber pad, and the rollers as a whole move forward with the chain; at this time, the rollers self-rotate due to the friction of the rubber pad, and the apple between the two adjacent rollers is clamped by the two rollers and moves forward, the self-rotation of the rollers promotes the adjustment of the posture of the apple, so that the apple assumes a side-lying state, and when the photoelectric sensor receives a signal, the step motor stops conveying, and the netting device sucks the apple with adjusted posture to facilitate subsequent netting and flower pulling work.

[0013] The rollers are mainly divided into two parts: one is the apple posture adjusting area, i.e. the middle concave part, and the other is the friction self-rotation area. Through the design of the roller structure, the apple with adjusted posture is obtained for flower pulling.

[0014] Further, the upper fruit taking mechanism includes a vacuum suction cup, the vacuum suction cup is installed at the end of the piston rod of a double-rod double-shaft cylinder, the double-rod double-shaft cylinder is fixed at the end of the crossbeam of the L-shaped rotating support, and the bottom of the vertical rod of the L-shaped rotating support is connected with a step motor D through a coupling.

[0015] The beneficial effects of the above technical features in the application are that the upper fruit taking mechanism moves the vacuum suction cup between the apple posture adjusting mechanism, the secondary netting module and the apple boxing mechanism through the control of the step motor D, and the suction cup can convey the apple to the corresponding position.

[0016] Further, a vacuum generator is installed on the crossbeam of the L-shaped rotating support, and the vacuum generator is connected with the vacuum suction cup.

[0017] The role of the above technical features in the application is to provide power for the vacuum suction cup.

[0018] Further, the apple boxing mechanism includes an upper marking device, a conveying belt platform and a horizontal moving platform; the upper marking device includes a labeling head, the labeling head is installed on a head base plate, the head base plate is hung on a rack through a light lever A, and the head base plate is also connected with a motor through a belt A; the labeling head is hung above a conveying bracket of the conveying belt platform, a transmission belt or a roller shaft row driven by a motor A is also installed on the upper surface of the conveying bracket; the conveying bracket is installed above a horizontal moving bracket through a horizontal moving light lever and a horizontal moving belt; the horizontal moving bracket is installed above a longitudinal moving bracket through a longitudinal moving light lever and a longitudinal moving belt.

[0019] The beneficial effects of the above technical features in the application are that: the angle of rotation of the fruit taking mechanism is relatively fixed, in order to realize that the fruit taking mechanism places apples in the corresponding position in the box, through the setting of the multi-layer platform combination of the apple packing mechanism, the cross movement of the horizontal moving bracket and the conveying bracket can adjust the position of the fruit box, and ensure that the apples are placed in the corresponding position in the box.

[0020] Further, the net cover posture adjusting mechanism comprises a net cover lifting conveyor belt obliquely installed in the net cover box, a blocking strip is arranged on the belt surface of the net cover lifting conveyor belt, a fan is installed at the side of the top of the net cover lifting conveyor belt, a net cover falling box is installed at the opposite side of the fan, the net cover falling box is in the shape of L-shaped steps as a whole, the net cover falling box comprises a box lower plate and a box upper plate, a sliding channel is formed between the box lower plate and the box upper plate, and the bottom of the sliding channel is in the shape of a bell mouth; a blower is installed at the steps outside the net cover falling box, and the blowing port of the blower points to the bell mouth part of the sliding channel.

[0021] The beneficial effects of the above technical features in the application are that: the lowest positions of the inclined edges on the two sides of the flared part of the bell mouth channel in the net cover falling box are staggered, one side is high and the other side is low, so that the net cover falling into the channel will be blocked by the two sides and subjected to different forces, so that the posture of the net cover will be adjusted during the falling process, and the net cover will be in the state of opening downward when falling.

[0022] The specific use method of the apple gift box packaging production line based on the flower-shaped net cover is that,

[0023] Step 1, prepare the net cover, and put the cut net cover into the net cover posture adjusting mechanism of the net cover box;

[0024] Step 2, after the net cover posture adjusting mechanism adjusts the posture of the net cover, the net cover is sent into the first net cover supporting module of the two-stage net cover supporting mechanism one by one, and the net cover is supported by the first net cover supporting module and the second net cover supporting module;

[0025] Firstly, the scattered net covers in the net cover box are lifted one by one between adjacent blocking strips under the continuous movement of the net cover lifting conveyor belt, and then the net cover is blown into the net cover falling box by the fan after being lifted to the top of the net cover lifting conveyor belt. During the sliding process of the net cover in the net cover falling box, the net cover falls from the net cover falling box in the state of opening downward after passing the position of the bell mouth, and the posture of the net cover during falling is adjusted; the falling net cover is received by the first net cover supporting module and falls into the box-shaped structure of the first net cover supporting module.

[0026] The box-shaped structure of the primary support mesh module consists of two support wood boards, side baffles on both sides, and a retractable mesh receiving baffle. The mesh receiving baffle acts as a base plate and moves back and forth. When the mesh sleeve falls, the mesh receiving baffle stops it, the opening of the mesh sleeve faces downwards, and the two support wood boards on both sides move closer together. The mesh sleeve is then held in place by nano-adhesive on the inside. Moving the mesh receiving baffle backwards pulls the mesh sleeve open. After being pulled open to the designed opening, the primary support mesh module moves downwards and places the mesh sleeve onto the ends of the two closed mechanical claws. The length of the mesh sleeve on the mechanical claws is [length missing]. From 1 / 3 to 1 / 2, the supporting wooden board continues to separate, leaving the netting on the mechanical claw. After the first-level supporting module and the netting are separated, the first-level supporting module moves upward to perform a second operation. Under the action of stepper motor B, the mechanical claw of the second-level supporting module separates to both sides. The gap between the two sides is large enough to accommodate an apple. The upper part of the netting after it is opened is in a contracted state due to the characteristics of the netting itself. When the apple falls, it is pressed against the contracted part. Under the action of gravity, the netting wrapped around the outside of the apple forms a bent double-layer structure, which is the flower-wrapping effect.

[0027] Step 3: While the netting posture adjustment mechanism is working, the apple posture adjustment mechanism adjusts the apple's posture to a lying position through the action of the rollers. The apple is placed between two adjacent rollers of the apple posture adjustment mechanism. Since the middle of the roller is concave, the design of the concave shape is similar to the shape of the apple. Thus, the roller moves in one direction driven by the chain. At the same time, the roller contacts the rubber plate. The friction between the roller and the rubber plate causes the roller to rotate. That is, while the roller moves in one direction, it also rotates itself. Under the action of force, the apple between the rollers is deflected and gradually adjusted into a lying position during the lateral movement, that is, the apple's stem is pointing laterally.

[0028] Step 4: The upper fruit-picking mechanism picks up the apples that have been adjusted in step 3 using the suction of a vacuum suction cup. The upper fruit-picking mechanism rotates horizontally by 90° to transfer the apples from the apple posture adjustment mechanism to the open net sleeve. The apples with the net sleeve are then transferred horizontally by the upper fruit-picking mechanism by 90° and sent into the apple packing mechanism.

[0029] Step 5: The apple packing mechanism adjusts the relative positions of the apples in the fruit box and the labeling mechanism by moving the fruit box and the labeling mechanism on top, and then affixes labels to the apples. Attached Figure Description
