DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a buffer unloading device for a bottle blowing machine, comprising a collecting box 1, a buffer channel 2 is embedded on one side of the top of the collecting box 1, the top of the buffer channel 2 is threadedly connected to the outer wall of one side of the base 3, a transmission device 4 is provided on the top of the base 3, and an injection mechanism 5 is provided on the front and rear outer walls of the base 3. A hydraulic cylinder 6 is threadedly installed on the bottom wall of the base 3, and an electromagnetic plate 7 is provided at the driving end of the hydraulic cylinder 6. A limiting mechanism 8 is adsorbed on the top of the electromagnetic plate 7, and a screw capping mechanism 9 is provided on the front and rear outer walls of the limiting mechanism 8.

[0022] In this embodiment, Figure 1 and Figure 3As shown, the buffer channel 2 is composed of a guard plate 201, a slide 202 and a spring plate 203, wherein the guard plate 201 is arranged on the left and right outer walls of the slide 202, and a plurality of spring plates 203 are also arranged on the surface of the slide 202; it should be noted that when the operator uses the transmission device 4 to transmit a group of blow bottles to the end of the base 3, the position limit of the blow bottles can be released first, and then the jet mechanism 5 is started to blow the blow bottles placed on the transmission device 4 to the buffer channel 2 in sequence, so that the blow bottles can slide along the slide 202 to the collection box 1 below. During this process, the blow bottles will touch three spring plates 203 with gradually gentle slopes in sequence, and when the bottle body of the blow bottle slides to the top of the spring plate 203, it will squeeze the spring at the bottom of the spring plate 203. At the same time, the spring absorbs and disperses the impact force suffered by the blow bottle itself, thereby achieving buffered feeding of the blow bottle. During this period, the guard plate 201 arranged on the left and right outer walls of the slide 202 plays a protective role for the blow bottle.

[0023] In this embodiment, Figure 2 and Figure 3 As shown, the transmission device 4 is composed of a driving motor A401, a rotating plate 402, a transmission main shaft 403, a transmission slave shaft 404 and a transmission crawler 405, wherein the transmission main shaft 403 and the transmission slave shaft 404 respectively penetrate the interior of the rotating plate 402 at the head and tail ends of the top of the base 3, and the transmission crawler 405 is also sleeved on the outer wall of the shaft body of the transmission main shaft 403 and the transmission slave shaft 404, and the driving motor A401 is also plugged into one end of the transmission main shaft 403; it should be noted that when the operator starts the hydraulic cylinder 6 to drive the entire limiting mechanism 8 and the bottle blowing lower body placed therein, When it is lowered to the transmission device 4, the supporting bottom frame 801 in its limiting mechanism 8 will fit on the upper surface of the transmission crawler 405. At this time, the operator can start the driving motor A401 to make its output end start to rotate and drive the transmission main shaft 403 connected to it to rotate together. The transmission crawler 405 sleeved on the outer wall of the transmission main shaft 403 can drive the transmission slave shaft 404 at the other end to rotate together. At the same time, the limiting mechanism 8 placed on the top of the transmission crawler 405 will be transported to the buffer channel 2 together with the blow-bottle placed inside it by the transmission crawler 405, and automatic unloading will be completed.

[0024] In this embodiment, Figure 2 and Figure 3As shown, the jet mechanism 5 is composed of a fixed frame 501, a supporting clamp rod 502 and a jet 503, wherein the fixed frame 501 is screwed to the front and rear outer walls of the base 3, and a supporting clamp rod 502 is vertically penetrated in the middle of the top of the fixed frame 501, and a jet 503 is clamped inside the supporting clamp rod 502; it should be noted that when the limiting mechanism 8 and the blow bottle placed inside are transported to the buffer channel 2 by the transmission crawler 405, the operator can stop the drive motor A401 and start the jet 503 instead, because the jet 503 in the jet mechanism 5 provided in the present unloading device can be just aligned with the middle of the blow bottle, so that when it is started, the jet 503 will quickly spray compressed air from its nozzle on the blow bottle body, thereby blowing the entire blow bottle to the outlet of the buffer channel 2 in turn, and slide down the landslide 202 to the collection box 1 provided with an elastic sponge, completing the blowing unloading operation.

[0025] In this embodiment, Figure 4 As shown, the limiting mechanism 8 is composed of a supporting bottom frame 801, a supporting top frame 802, an electric push rod 803, a connecting rod 804 and a baffle 805, wherein the top of the supporting bottom frame 801 is welded with a supporting top frame 802, and the bottom wall of the supporting top frame 802 is provided with a plurality of strip grooves for the baffle 805 to pass through, and an electric push rod 803 is provided at the bottom of the baffle 805, and each electric push rod 803 is connected by a connecting rod 804; it should be noted that before the entire unloading device is used, the entire limiting mechanism 8 is placed in close contact with the top of the transmission crawler 405. At this time, the operator can first energize and magnetize the electromagnetic plate 7, and then start the hydraulic cylinder 6, so that its driving end, together with the electromagnetic plate 7 with magnetization on the top, passes through the top of the base 3 and the supporting bottom frame 801 in sequence, and finally adsorbs on the bottom of the supporting top frame 802. At the same time, the driving end of the hydraulic cylinder 6 will push the entire limiting mechanism adsorbed on its top The limiting mechanism 8 rises together until it reaches the bottle blowing position. At this time, the bottle is loosened by the capping mechanism 9, so that it is separated from the previous unit and falls directly onto the bottom wall of the supporting top frame 802, and then the hydraulic cylinder 6 is controlled to retract its driving end to drive the bottle in the limiting mechanism 8 to fall back to its original position. During this period, the baffle 805 has been separating and protecting each bottle. When the entire limiting mechanism 8 is reattached to the top of the transmission crawler 405, the operator can cut off the power supply of the electromagnetic plate 7 to make it lose its magnetism, and then drive the driving end of the hydraulic cylinder 6 to retract to the inside of the base 3 to release the adsorption and fixation of the limiting mechanism 8. At the same time, the operator can start the transmission device 4 to transfer the limiting mechanism 8 and the bottle to the buffer channel 2 together, and at the same time start the electric push rod 803 through the external controller to drive the baffles 805 at their respective positions to be retracted to the inside of the supporting bottom frame 801 through the strip groove, thereby releasing the position limitation of the bottle.

[0026] In this embodiment, Figure 5 As shown, the cover screwing mechanism 9 is composed of a push plate 901, a telescopic rod 902, a support sleeve rod 903, a driving gear 904, a driven gear 905, a driving motor B906 and a transmission chain belt 907, wherein the driving gear 904 and the driven gear 905 are both horizontally penetrated into the interior of the supporting top frame 802 through the rotating shaft of the inner wall thereof, and the driving motor B906 is also plugged into the inner wall of the driving gear 904, and the teeth of the driving gear 904 and the driven gear 905 are also meshed with a transmission chain belt 907. The chain belt 907 is welded with a support sleeve rod 903 on the top of the transmission chain belt 907, and a telescopic rod 902 is sleeved on the inner wall of the support sleeve rod 903, and a push plate 901 is welded on the driving end of the telescopic rod 902; it should be noted that the operator pushes the entire limiting mechanism 8 up to the bottle blowing position through the electromagnetic plate 7 and the hydraulic cylinder 6. At this time, the push plate 901 in the capping mechanism 9 is just a little below the bottle mouth of the bottle blowing, and then the operator can control it through the external The device drives the telescopic rod 902, so that the telescopic rod 902 can push the push plate 901 on the opposite side gradually approach the middle bottle mouth of the bottle blowing, and finally closely adhere to its outer wall. At the same time, the operator can start the driving motor B906, so that the output end of the driving motor B906 starts to rotate, and drives the driving gear 904 plugged therein to start rotating. At this time, the transmission chain belt 907 meshed with the teeth on the outer wall of the driving gear 904 is also rotated together with the driven gear 905 provided at the other end. At this time, the supporting sleeve rod 903 welded to the top of the transmission chain belt 907 will move with the telescopic rod 902 sleeved on its inner wall and the push plate 901 welded at its driving end. Because the rotation direction of the output end of the driving motor B906 provided on the opposite side of the limiting mechanism 8 is opposite, during this period, the push plate 901 on the opposite side will also move in the opposite direction, thereby loosening the bottle mouth of the bottle blowing and making it detach from the previous unit.

[0027] The use method and advantages of the utility model: When the buffer feeding device of the bottle blowing machine is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, the operator can energize the electromagnetic plate 7 to magnetize it, and then start the hydraulic cylinder 6 to push the magnetized electromagnetic plate 7 to be adsorbed on the bottom of the supporting top frame 802. At the same time, the driving end of the hydraulic cylinder 6 will continue to push the limiting mechanism 8 adsorbed on its top to rise until it reaches the bottle blowing position. At this time, the two driving motors B906 with opposite rotation directions are started again, and the two push plates 901 arranged on the top thereof are driven to move in opposite directions through the active gear 904 and the transmission chain belt 907 meshing therewith, so as to loosen the bottle mouth of the blown bottle, make it detach from the upper unit, and directly fall on the bottom wall of the supporting top frame 802, and then control the hydraulic cylinder 6 to retract the driving end to drive the blown bottle in the limiting mechanism 8 to return to its original position, and the entire limiting mechanism 8 is re-attached to the transmission track. When the belt 405 reaches the top, the power supply of the electromagnetic plate 7 is cut off, and the driving end of the hydraulic cylinder 6 is driven to retract to its original position, and the adsorption and fixation of the limiting mechanism 8 is released. At the same time, the operator starts the transmission device 4 again to transmit the limiting mechanism 8 and the blow bottle to the buffer channel 2, and starts the electric push rod 803 to drive the baffle 805 to retract to the inside of the supporting bottom frame 801, and the position limit of the blow bottle is released. Then the jet 503 is started, so that the jet 503 quickly sprays compressed air from its nozzle to the blow bottle body, thereby blowing the entire blow bottle to the outlet of the buffer channel 2 in turn, and slides down along the landslide 202, thereby touching the three spring plates 203 in turn, reducing the impact force suffered by the blow bottle itself, thereby realizing buffered unloading, until the blow bottle falls into the collection box 1 provided with an elastic sponge, and the blowing unloading operation is completed.
