A plastic bottle blow molding bottle mouth cutting device includes an operating table, a support frame is fixedly connected to the upper surface of the operating table, a cross beam is fixedly connected to one side of the support frame, and a hydraulic cylinder is fixedly connected to one end of the cross beam; in this utility model, by setting a hydraulic cylinder, a support plate, a spring cylinder, a spring, a limiting plate and a limiting rod, when in use, first place the plastic bottle on the lower fixing plate, and then start the hydraulic cylinder. During the descending process, the upper fixing plate first contacts the plastic bottle, the limiting rod drives the limiting plate to move to compress the spring, and the reaction force generated by the spring compression is fed back to the upper fixing plate, and the upper fixing plate can complete the fixation of the plastic bottle together with the lower fixing plate, greatly simplifying the fixation process of the plastic bottle, thereby achieving the characteristic of high working efficiency of this device.

[0003] However, during the use of this utility model, after placing the plastic bottle on the lower fixing plate, it is necessary for the staff to manually adjust the position of each plastic bottle so that the positions on the plastic bottle that need to be cut correspond to the cutting blades. The process of adjusting the plastic bottle is time-consuming and inconvenient. And this process only relies on the naked eye observation and manual adjustment of the staff, and it is inevitable that there will be a deviation between the cutting blade and the position on the plastic bottle that needs to be cut.

[0004] Therefore, the utility model proposes a technical solution to solve the problems that the process of adjusting the plastic bottle is time-consuming and inconvenient and is prone to deviation. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a plastic bottle bottle mouth cutting device, aiming to achieve the technical effect that after placing the plastic bottle on the lower fixing plate, the positions on the plastic bottle that need to be cut correspond to the cutting blades, without repeatedly adjusting the plastic bottle, which is more time-saving and convenient, and can avoid the situation of deviation between the cutting blade and the positions on the plastic bottle that need to be cut.

[0006] A plastic bottle neck cutting device, comprising a base, an operating table, a support frame, a top beam, a hydraulic cylinder, a support plate, a spring cylinder, an upper fixing plate, a connecting rod, a cutting blade and a lower fixing plate. The lower fixing plate and the upper fixing plate are parallel to each other, and a plurality of fixing grooves are formed on the opposite sides thereof. The upper fixing plate is above the left side of the top of the lower fixing plate. A first motor is installed on the outer side wall of the operating table. A cavity located on the left side of the lower fixing plate is formed inside the operating table. A rotating shaft is rotatably connected in the cavity through a bearing. Two driving gears are fixedly sleeved on the outer part of the rotating shaft. One end of the rotating shaft penetrates out of the operating table and is connected with the output shaft of the first motor through a coupling. Two sliding grooves are formed on the top of the operating table, and the two sliding grooves are respectively located on the front and rear sides of the lower fixing plate. A lead screw is rotatably connected in the sliding groove through a bearing. One end of the lead screw penetrates into the cavity and is fixed with a driven gear meshing with the driving gear. A nut seat is sleeved on the outer part of the lead screw in a threaded connection manner. The nut seat moves along the sliding groove, and the outer side wall thereof fits with the groove wall of the sliding groove. The top of the nut seat penetrates out of the sliding groove and is fixed with an extension rod. The top of the extension rod extends above the lower fixing plate and is fixed with a fixing block. A sliding rod is connected between the two fixing blocks. A plurality of baffles corresponding to the fixing grooves are fixedly sleeved on the outer part of the sliding rod. The bottom end of the baffle penetrates into the fixing groove and slides along the fixing groove.

[0007] By adopting the above technical solution, before placing the plastic bottle on the lower fixing plate, first adjust the position of the baffle according to the length of the plastic bottle and the position where it needs to be cut. After the plastic bottle is placed in the fixing groove, the bottom of the plastic bottle is in contact with the baffle. At this time, the position where the plastic bottle needs to be cut just corresponds to the cutting blade. There is no need to repeatedly adjust the plastic bottle, which is more time-saving and convenient, and can accurately correspond the position where the plastic bottle needs to be cut with the cutting blade, avoiding the deviation between the cutting blade and the position where the plastic bottle needs to be cut. The adjustment process of the baffle is as follows: start the first motor, and the output shaft of the first motor rotates to drive the rotating shaft to rotate. The rotating shaft drives the driving gear fixedly connected thereto to rotate. The driving gear drives the driven gear meshing therewith to rotate. The driven gear drives the lead screw fixedly connected thereto to rotate. The rotation of the lead screw drives the nut seat to move along the sliding groove. The nut seat drives the extension rod to move. The extension rod drives the fixing block to move. The fixing block drives the sliding rod to move. The sliding rod drives the baffle to move. The bottom end of the baffle slides in the fixing groove, thereby adjusting the position of the baffle. After the plastic bottle of the present utility model is placed on the lower fixing plate, the position where the plastic bottle needs to be cut corresponds to the cutting blade, without repeatedly adjusting the plastic bottle, which is more time-saving and convenient, and can avoid the situation of deviation between the cutting blade and the position where the plastic bottle needs to be cut.

[0008] A further setting of the present utility model: both the lower fixing plate and the upper fixing plate are arranged in a downward inclined shape from left to right.

[0009] By adopting the above technical solution, after the plastic bottle is placed in the inner fixing groove of the lower fixing plate, under the action of its own gravity, it automatically slides downward along the fixing groove, ensuring that the bottom of the plastic bottle is in close contact with the baffle. And it can avoid the plastic bottle from shifting due to force after the upper fixing plate descends and presses the plastic bottle.

[0010] A further setting of the present utility model: The sliding rod is rotatably connected between two fixing blocks through bearings, and a second motor for driving the sliding rod to rotate is installed on one of the fixing blocks.

[0011] By adopting the above technical solution, when the cutting is completed and the plastic bottle needs to be taken out, the second motor is started. The second motor drives the sliding rod to rotate, and the sliding rod drives the baffle to rotate upward. The bottom end of the baffle is no longer located in the fixing groove. At this time, under the action of the gravity of the plastic bottle itself, the plastic bottle automatically slides out of the fixing groove. There is no need to take out each cut plastic bottle one by one, and the taking-out process is more convenient.

[0012] A further setting of the present utility model: A fixing seat is fixed at the top end of the base, the operating table is fixed at the top end of the fixing seat, and a collection box located on the right side of the lower fixing plate is also placed at the top end of the base. The height of the top end of the collection box is lower than the right side of the lower fixing plate.

[0013] By adopting the above technical solution, the setting of the fixing seat can raise the lower fixing plate, so that there is a certain height interval between the right side of the lower fixing plate and the base. The plastic bottle can fall into the collection box for collection after sliding downward along the fixing groove.

[0014] A further setting of the present utility model: A sponge pad is fixed on the inner side wall of the collection box.

[0015] By adopting the above technical solution, the setting of the sponge pad can prevent the plastic bottle from being damaged by bumping against the inner side wall of the collection box when it falls into the collection box.

[0016] A further setting of the present utility model: Scale lines for displaying the position of the baffle are engraved on the top end of the operating table.

[0017] By adopting the above technical solution, the staff can move the baffle to the required position more quickly by observing the index corresponding to the scale line on the nut seat.

[0028] The operating table 2 is parallel to the upper fixing plate 8. A fixing seat 12 is fixedly connected between the bottom end of the operating table 2 and the top of the base 1. A first motor 13 is installed on the outer side wall of the operating table 2. A cavity 14 extending horizontally in the front and back directions is provided inside the operating table 2. A rotating shaft 15 is rotatably connected inside the cavity 14 through a bearing. Two driving gears 16 are fixedly sleeved on the outside of the rotating shaft 15. One end of the rotating shaft 15 passes through the operating table 2 and is connected to the output shaft of the first motor 13 through a coupling. Two symmetrically arranged chutes 17 are provided at the top of the operating table 2 in the front and back directions. The extending direction of the chutes 17 is the same as that of the operating table 2. A lead screw 18 is rotatably connected inside the chute 17 through a bearing. One end of the lead screw 18 penetrates into the cavity 14 and is fixed with a driven gear 19 meshing with the driving gear 16. A nut seat 20 is sleeved on the outside of the lead screw 18 in a threaded connection manner. The nut seat 20 moves along the chute 17 and its outer side wall fits with the groove wall of the chute 17. The top end of the nut seat 20 penetrates out of the chute 17 and is fixed with an extension rod 21 perpendicular to the operating table 2. A fixing block 22 is fixed to the top end of the extension rod 21. A sliding rod 23 parallel to the operating table 2 is rotatably connected between the two fixing blocks 22 through a bearing. A plurality of baffle plates 24 are fixedly sleeved on the outside of the sliding rod 23. A second motor 25 for driving the sliding rod 23 to rotate is installed on one of the fixing blocks 22.

[0029] The lower fixing plate 11 is fixed to the top of the operating table 2 and is parallel to the operating table 2 and the upper fixing plate 8. The left side of the top end of the lower fixing plate 11 corresponds to the lower side of the upper fixing plate 8. The lower fixing plate 11 is located between the sliding rod 23 and the operating table 2. The lower fixing plate 11 is located between the two chutes 17. A plurality of lower fixing grooves 26 are provided at the top end of the lower fixing plate 11. A plurality of upper fixing grooves (not shown in the figure) are provided at the bottom end of the upper fixing plate 8. The plurality of lower fixing grooves 26 correspond to the plurality of baffle plates 24 one by one, and the bottom end of the baffle plate 24 can penetrate into and slide in the lower fixing groove 26.

[0030] A collection box 27 is also placed on the top of the base 1 on the right side of the lower fixing plate 11. The height of the top end of the collection box 27 is lower than the right side of the lower fixing plate 11. A sponge pad (not shown in the figure) is fixed to the inner side wall of the collection box 27.

[0031] Additionally, the top of the operating table 2 is engraved with scale lines (not shown in the figure) for displaying the position of the baffle 24. By observing the index corresponding to the scale line on the nut seat 20, the staff can move the baffle 24 to the required position more quickly.

[0032] Working principle: Before placing the plastic bottle on the lower fixing plate 11, first adjust the position of the adjusting baffle 24 according to the length of the plastic bottle and the position where it needs to be cut. After the plastic bottle is placed in the fixing groove, under the action of its own gravity, it automatically slides downward along the fixing groove, and the bottom of the plastic bottle comes into contact with the baffle 24. At this time, the position where the plastic bottle needs to be cut just corresponds to the cutting blade 10.

[0033] Then, the cutting blade 10 and the upper fixing plate 8 are moved downward by the hydraulic cylinder 5. The upper fixing plate 8 first contacts the plastic bottle, and then under the contraction of the spring cylinder 7, the upper fixing plate 8 and the lower fixing plate 11 cooperate to clamp the plastic bottle. At this time, since the plastic bottle is inclined against the baffle 24 under the action of its own gravity, after the upper fixing plate 8 presses the plastic bottle, it can prevent the plastic bottle from shifting due to the force.

[0034] As the spring cylinder 7 contracts, the cutting knife contacts the plastic bottle to cut the plastic bottle.

[0035] When the cutting is completed and the plastic bottle needs to be taken out, the second motor 25 is started. The second motor 25 drives the slide bar 23 to rotate, and the slide bar 23 drives the baffle 24 to rotate upward. The bottom end of the baffle 24 is no longer located in the lower fixing groove 26. At this time, under the action of the gravity of the plastic bottle itself, the plastic bottle automatically slides out of the lower fixing groove 26. There is no need to take out each cut plastic bottle one by one, and the taking-out process is more convenient. After the plastic bottle slides down along the lower fixing groove 26, it can fall into the collection box 27 for collection. The setting of the sponge pad can prevent the plastic bottle from being damaged by bumping against the inner wall of the collection box 27 when it falls into the collection box 27.

[0036] The adjustment process of the baffle 24 is as follows: Start the first motor 13. The output shaft of the first motor 13 rotates to drive the rotating shaft 15 to rotate. The rotating shaft 15 drives the driving gear 16 fixedly connected thereto to rotate. The driving gear 16 drives the driven gear 19 meshing with it to rotate. The driven gear 19 drives the lead screw 18 fixedly connected thereto to rotate. The lead screw 18 rotates to drive the nut seat 20 to move along the chute 17. The nut seat 20 drives the extension rod 21 to move. The extension rod 21 drives the fixed block 22 to move. The fixed block 22 drives the slide bar 23 to move. The slide bar 23 drives the baffle 24 to move. The bottom end of the baffle 24 slides in the fixing groove, thereby adjusting the position of the baffle 24.

[0037] After placing the plastic bottle on the lower fixing plate 11, the position on the plastic bottle to be cut corresponds to the cutting blade 10. There is no need to repeatedly adjust the plastic bottle, which is more time-saving and convenient. Moreover, it can accurately correspond the position on the plastic bottle to be cut with the cutting blade 10, avoiding the situation of deviation between the cutting blade 10 and the position on the plastic bottle to be cut.
