[0021] The present invention has at least the following beneficial effects:

[0022] 1. When the driving gear rotates, it drives the positioning rod meshing with it to move, thereby driving the push plate to make a reciprocating motion according to the direction of the limit rail, reciprocatingly feeding the product into the main body, and performing continuous and efficient sealing and packaging of the product. When the product reaches the top of the feed belt and one side of the movable wheel, the "L"-shaped correcting plate pushes the product to the center and reaches the inside of the main body. The correcting plate can also block other products in the feed belt from entering the main body, so that the main body is sealed and packaged in an orderly manner.

[0023] 2. Under the thrust of the pushing component, the transmission tooth plate on one side of the correcting plate reaches the position of the connecting gear and engages with the connecting gear. Then the correcting plate drives the synchronization component to start running, so that the film-releasing wheels rotate inward at the same time and release the film at a constant speed. When the product enters the sealing film, the film-releasing wheels release the film at the same time. The sealing film can be tightened to reduce wrinkles generated during packaging, so that the sealing film can fit the surface of the product and avoid pulling force on the sealing film when the product is pushed, effectively reducing the possibility of breaking the sealing film. At the same time, it reduces power consumption, improves production efficiency and reduces production costs.

[0024] 3. When the deflection-correcting plate moves backward, the horizontal position of the deflection-correcting plate will be raised according to the running track of the limit rail, and then the deflection-correcting plate will drive the interlocking gear plate to deviate from the original horizontal line. The synchronous component is not controlled by the deflection-correcting plate. The setting can prevent the transmission gear plate from driving the interlocking gear to move in the opposite direction, causing the film-releasing wheels to rotate in the opposite direction, the sealing film to rewind, and the sealing film to break.

[0047] Synchronous component 007, synchronous component 007 is arranged on one side of the anti-wear frame, and is used to make the film placing wheel 003 and the correcting plate 005 operate simultaneously.

[0048] Among them, the staff can place the grinding wheel rack in the film placing rack 002, and then unfold the sealing film through the film placing wheel 003. According to the position of the pressure rod 140, the sealing film is wrapped around the feed belt 004 half a circle, and the tail end of the sealing film is wound on the waste film reel 820 according to the position of the film receiving wheel 810. Then, the motor in the pushing component 006 can be started, and the motor drives the pushing component 006 to move the correcting plate 005 back and forth, so that the correcting plate 005 continuously pushes the product in the feed belt 004. During the pushing process, the pushing component 006 can drive the synchronous component 007, and the synchronous component 007 can drive the film placing wheel 003, so that the film placing wheel 003 places the sealing film, and then when the correcting plate 005 pushes the product into the main body 001, the film placing wheel 003 can put down the sealing film, so as to avoid excessive pulling of the sealing film by the product, which causes the sealing film to break.

[0049] Two film placing wheel racks 210 are set at the top of the film placing rack 002. A film wheel 220 is detachably connected between the two film placing wheel racks 210. The film placing wheel racks 210 and the film wheel 220 form a rotating connection. The film placing wheel pair 003 is located in front of the film wheel 220.

[0050] Among them, there is a small gap between the film placing wheels 003. The staff can put the bottom of the sealing film into the gap, and then rotate the wheels to roll the sealing film under the wheels, and then the sealing film can be used.

[0051] A three-phase motor 110 is installed inside the main body 001, and a sealing and cutting knife 120 is provided at the bottom end of the three-phase motor 110. A cutting plate 130 is provided below the sealing and cutting knife 120, and the cutting plate 130 is fixedly connected to the main body 001. A pressure rod 140 is provided on the front side of the cutting plate 130, and both ends of the pressure rod 140 are fixedly connected to a slider 150. A movable groove 160 is provided on the outer side of the slider 150, and the slider 150 and the movable groove 160 are slidably connected. Two return springs 170 are provided inside the movable groove 160, and the two return springs 170 are positioned above the slider 150.

[0052] Among them, the staff can hold the pressure rod 140 and lift it upward, and then use the pressure rod 140 to press the sealing film so that the sealing film can wrap one side of the feeding belt 004. After the staff lets go, under the action of the return spring 170, the pressure rod 140 and the slider 150 are immediately driven to press the sealing film downward. The arrangement makes it easy for the staff to install the sealing film and simplifies the staff's operation process.

[0053] A fixed frame 410 is provided at the front end of the feeding belt 004, and a plurality of movable wheels 420 are movably connected at equal intervals inside the fixed frame 410. The fixed frame 410 is fixedly connected to the main body 001, and the correction plate 005 is provided on one side of the fixed frame 410. The shape of the correction plate 005 is set to be "L"-shaped, and the width of the correction plate 005 is equal to the width of the feeding belt 004.

[0054] Among them, the setting of the movable wheel 420 is convenient for reducing the friction generated when pushing the product, so that the product can smoothly reach the inside of the main body 001.

[0055] The pushing assembly 006 includes a pushing plate 601, a limiting rail 602, a positioning rod 603, a driving gear 604 and a first movable shaft 605. The outer wall of the pushing plate 601 is fixedly connected to the limiting rail 602. The limiting rail 602 is elliptical in shape. A plurality of positioning rods 603 are arranged inside the limiting rail 602. The plurality of positioning rods 603 are equidistantly distributed in an elliptical shape about the outer wall of the pushing plate 601. The outer wall of the positioning rod 603 is meshed with the driving gear 604. The front end of the driving gear 604 is provided with a first movable shaft 605. The first movable shaft 605 is arranged inside the limiting rail 602. The first movable shaft 605 and the limiting rail 602 form a sliding connection.

[0056] A positioning plate 610 is provided on one side of the push plate 601, and the positioning plate 610 is fixedly connected to the main body 001. A sliding groove 620 is provided inside the positioning plate 610, and the running trajectory of the sliding groove 620 is coordinated with the running trajectory of the limiting rail 602. The inner wall of the sliding groove 620 is slidably connected with a second movable shaft 630, and the second movable shaft 630 is set to be fixedly connected to the push plate 601. The position of the second movable shaft 630 is set at the diagonal position of the first movable shaft 605.

[0057] Among them, a motor is installed at the rear end of the driving gear 604. The staff can start the motor to drive the driving gear 604. When the driving gear 604 rotates, it can drive the positioning rod 603 engaged with it to move, thereby driving the push plate 601 to make a reciprocating motion according to the direction of the limiting rail 602, and reciprocatingly feed the product into the interior of the main body 001 to continuously package the product. When the product reaches the top of the feeding belt 004 and the side of the movable wheel 420, the "L"-shaped correcting plate 005 pushes the product so that the product is centered and reaches the interior of the main body 001, and the correcting plate 005 can block other products in the feeding belt 004 from entering the interior of the main body 001, so that the main body 001 is sealed and packaged in an orderly manner. At the same time, the first movable shaft 605 slides on the inner wall of the slide groove 620. The setting of the first movable shaft 605 is convenient for limiting the pushing plate 601, so that the pushing plate 601 runs according to the established trajectory.

[0058] The synchronization component 007 includes a transmission gear 701, a bevel gear 702, a transmission rod 703, a fixed box 704, a linkage gear 705 and a transmission tooth plate 706. There are two transmission gears 701, and the two transmission gears 701 are respectively fixedly connected to the film-releasing wheels 003. The side of one of the transmission gears 701 is meshed with the bevel gear 702, and the bottom end of the bevel gear 702 is fixedly connected to the transmission rod 703. The bottom end of the transmission rod 703 passes through the fixed box 704, and the internal rotation of the fixed box 704 is connected to the linkage gear 705. The linkage gear 705 is fixedly connected to the transmission rod 703, and the outer wall of the linkage gear 705 is meshed with the transmission tooth plate 706. The rear end of the transmission tooth plate 706 is fixedly connected to the correction plate 005.

[0059] The bottom end of the linkage gear 705 is fixedly connected to a ratchet 710 , and the front and rear sides of the ratchet 710 are meshedly connected to pawls 720 . The rear ends of the pawls 720 are provided with telescopic springs 730 , and the rear ends of the telescopic springs 730 are fixedly connected to the fixed box 704 .

[0060] Among them, when the correcting plate 005 moves toward the sealing and cutting knife 120 under the action of the pushing component 006, the transmission tooth plate 706 on one side of the correcting plate 005 reaches the position of the connecting gear 705 and engages with the connecting gear 705, so that the correcting plate 005 drives the connecting gear 705 to rotate, and the rotation of the connecting gear 705 drives the transmission rod 703 and the transmission gear 701 to rotate at the same time, and the two transmission gears 701 drive the film-releasing wheels 003 to rotate inward at the same time, releasing the film at a constant speed. When the product enters the sealing and cutting film, the film-releasing wheels 003 release the film at the same time, and are configured to tighten the sealing and cutting film, reduce wrinkles generated during the sealing and cutting film packaging, enable the sealing and cutting film to fit the surface of the product, and avoid pulling force on the sealing and cutting film when the product is pushed, effectively reducing the possibility of the sealing and cutting film breaking.

[0061] Among them, when the correction plate 005 moves backward, according to the running trajectory of the limit rail 602, the horizontal position of the correction plate 005 will be raised, and then the correction plate 005 drives the interlocking gear plate to deviate from the original horizontal line, and the transmission gear plate 706 loses the meshing connection with the interlocking gear 705, preventing the transmission gear plate 706 from driving the interlocking gear 705 to move in the reverse direction, causing the film placing wheel 003 to rotate in the reverse direction, the sealing film to rewind, and the sealing film to break.

[0062] The cooperation between the ratchet 710 and the pawl 720 further improves the operating safety of the linkage gear 705, avoids external interference with the linkage gear 705, and causes the linkage gear 705 to reverse, so that the device can operate normally.

[0063] The feeding belt 004 is provided with a first sensor 430 , and the first sensor 430 is located at the front end of the deviation correcting plate 005 .

[0064] Among them, when the correcting plate 005 runs towards the main body 001, the first sensor 430 will sense the "L"-shaped correcting plate 005, and then the first sensor 430 controls the feeding belt 004 to stop moving. The correcting plate 005 can push the product at the top of the feeding belt 004 and can separate other products.

[0065] An angle plate 008 is provided at the lower end of the main body 001, and the inner wall of the angle plate 008 is movably connected to the film collecting wheel 810, and the rear end of the film collecting wheel 810 is provided with a waste film reel 820, and the upper end of the waste film reel 820 is provided with a sliding rheostat 830, and the two ends of the sliding rheostat 830 are movably connected to small rollers 840, and the outer wall of the small roller 840 is in contact with the outer wall of the waste film reel 820, and the end of the sliding rheostat 830 is provided with a fixing frame 850, and the end of the fixing frame 850 is provided with a second sensor 860, and the second sensor 860 is provided on one side of the correction plate 005.

[0066] Among them, the film-retracting wheel 810 can tighten the tail end of the sealing film and roll the waste film of the sealing film onto the surface of the waste film reel 820. When the correcting plate 005 moves back, the second light sensor senses the "L"-shaped correcting plate 005, and can control the motor on the side of the waste film reel 820 to start, driving the waste film reel 820 to rewind the waste film. At the same time, when the waste film roller rotates driven by the motor, the waste film is wrapped around the surface of the waste film roller, and the small roller 840 rolls on the waste film. Then the small roller 840 can adjust the current of the sliding rheostat 830 according to the increase of waste film, so as to control the speed of the motor. The more waste film, the slower the motor, so that the sealing film can always be in a relatively taut state.

[0067] Example 2

[0068] like Figure 10-11 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that a transmission can be installed above the linkage gear 705, so that the staff can operate the rotation speed of the film placing wheel 003 according to the height of the product, thereby controlling the film placing speed so that the sealing film can fit the surface of the product.
