DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] In order to more clearly express the purpose of the utility model and the technical solution of the embodiment, the utility model is placed on a horizontal plane, the direction perpendicular to the horizontal plane is the vertical direction, the upper side along the vertical direction is the upper side, and the lower side is the lower side.

[0033] like Figure 1-6 As shown, the utility model provides a lifting adjustable sealing and cutting machine, comprising a frame 1, wherein a first working mechanism 2 is provided on one side of the frame 1 near the front end thereof, and a second working mechanism 3 is provided on one side near the rear end thereof, wherein the first working mechanism 2 comprises a first transport mechanism 21 and a film guiding mechanism 22 arranged on the upper and lower sides of the first transport mechanism 21, and a film feeding mechanism 11 is also provided on one side of the first working mechanism 2; the second working mechanism 3 comprises a second transport mechanism 31 and a film pulling mechanism 32, wherein the film pulling mechanism 32 is located on one side of the second transport mechanism 31, and a cutting mechanism 12 arranged up and down is also provided on the side of the second transport mechanism 31; the first transport mechanism 21, the second transport mechanism 31 and the film pulling mechanism 32 are synchronously operated, and the operating direction is from front to back;

[0034] When in use, the film 4 in the folded state is firstly arranged in the film feeding mechanism 11, and the film 4 is transported to the first working mechanism 2 through the film feeding mechanism 11. After the film 4 is transported to the first working mechanism 2, the film 4 is stretched into a "U"-shaped structure wrapped on the upper and lower sides of the first transport mechanism 21 through the film guiding mechanism 22, and the transport direction of the film 4 is consistent with the transport direction of the first transport mechanism 21 after being folded and deflected by the film guiding mechanism 22, that is, it is transported from front to back. At this time, the product 5 is placed on the first transport mechanism 21 and is located below the upper half 41 of the film 4. Under the action of the first transport mechanism 21, the product 5 is transported together with the film 4 to the direction of the second transport mechanism 31;

[0035] There is a gap (not shown) between the first transport mechanism 21 and the second transport mechanism 31, and the lower half 42 of the film 4 passes through the gap and extends to the top of the second transport mechanism 31 and fits with the upper half 41 of the film 4. After the film 4 is fitted, one side is located in the film-drawing mechanism 32, and the transport speed of the film 4 is controlled by the film-drawing mechanism 32; after the product 5 is transferred from the first transport mechanism 21 to the second transport mechanism 31, it is located above the lower half 42 of the film 4. At this time, the product 5 is wrapped by the "U"-shaped film 4, and when it moves to the corresponding position, the film-feeding mechanism 11, the film-drawing mechanism 32, the first transport mechanism 21 and the second transport mechanism 31 The work stops, the cutting mechanism 12 moves up and down and performs "L"-shaped sealing and cutting on the film 4 on the second transport mechanism 31, so that the film 4 on one side and the front end of the product 5 is sealed and cut to form a sealing and cutting line 43. Since the film 4 at the rear end of the product 5 has been sealed and cut by the sealing and cutting of the previous product 5, the four sides of the product 5 are sealed and wrapped by the film 4, thereby completing the sealing and cutting operation, and then the film feeding mechanism 11, the film pulling mechanism 32, the first transport mechanism 21 and the second transport mechanism 31 resume movement to perform the film sealing process of the next product 5; then, after the film 4 wrapped on the product 5 is heat-shrunk, the film 4 will be tightly attached to the outer surface of the product 5, thereby completing the film 4 packaging;

[0036] It should be noted that the sealing and cutting is to bond the upper half 41 and the lower half 42 of the film 4 together and separate them frontward and rearward or sideways by hot cutting, so that a sealing and cutting line 43 is formed at the separation point.

[0037] Specifically, Figure 4-6As shown, since the first working mechanism 2, the second working mechanism 3 and the cutter mechanism 12 are fixedly corresponding in horizontal height, the horizontal height of the sealing and cutting line 43 after the cutting mechanism 12 seals the product 5 is also relatively fixed. When the height of the product 5 changes, the height of the sealing and cutting line 43 of the film 4 after heat shrinkage relative to the product 5 will also change accordingly, thereby affecting the aesthetics of the film 4 packaging;

[0038] In order to solve the problem that the sealing and cutting line 43 changes in level with the height of the product 5, a lifting mechanism 6 is provided at the bottom of the first working mechanism 2 and the second working mechanism 3, and the lifting mechanism 6 can simultaneously drive the first working mechanism 2 and the second working mechanism 3 to synchronously adjust the level relative to the cutter mechanism 12, so as to achieve the purpose of adjusting the level of the sealing and cutting line 43; that is, when the position of the sealing and cutting line 43 on the product 5 after heat shrinkage is too high, the lifting mechanism 6 is used to increase the level of the first working mechanism 2 and the second working mechanism 3, so that the position of the sealing and cutting line 43 moves downward; when the position of the sealing and cutting line 43 on the product 5 after heat shrinkage is too low, the lifting mechanism 6 is used to lower the level of the first working mechanism 2 and the second working mechanism 3, so that the position of the sealing and cutting line 43 moves upward; through the setting of the lifting mechanism 6, the height position of the sealing and cutting line 43 is adjustable, so as to adapt to products 5 of different volumes, thereby achieving the purpose of beautifying the packaging of the film 4;

[0039] Furthermore, if Figure 7-9As shown, the lifting mechanism 6 includes at least two lifting devices 61, that is, at least one lifting device 61 for controlling the lifting of the first working mechanism 2 and the second working mechanism 3 is provided at the bottom; the lifting device 61 includes a fixed seat 611 fixedly connected to the frame 1, a lifting screw 612 and a threaded sleeve 613 fixedly connected to the bottom of the first working mechanism 2 or the second working mechanism 3, the fixed seat 611 is sleeved on the middle part of the lifting screw 612 and is rotatably connected to the lifting screw 612, one side of the fixed seat 611 is fixedly connected to the frame 1, and a bearing 614 is further provided between the fixed seat 611 and the lifting screw 612, through which the fixed seat 611 and the bearing 614 are connected. The setting makes the lifting screw 612 fixed under the first working mechanism 2 or the second working mechanism 3, and realizes free rotation under the premise of unchanged horizontal height, and through the setting of the bearing 614, the rotation of the lifting screw 612 can achieve a more labor-saving effect; at the same time, the upper end of the lifting screw 612 is provided with an external thread (not shown) corresponding to the internal thread (not shown) of the threaded sleeve 613. Since the top of the threaded sleeve 613 is fixedly connected to the bottom of the first working mechanism 2 or the second working mechanism 3, according to the screw principle, the horizontal height of the threaded sleeve 613 can be adjusted by rotating the lifting screw 612, thereby achieving the purpose of adjusting the horizontal height of the first working mechanism 2 or the second working mechanism 3;

[0040] Preferably, a hand wheel 615 is fixedly connected to the bottom of the lifting screw 612 of at least one of the lifting devices 61. When in use, the lifting screw 612 is driven to rotate by rotating the hand wheel 615, thereby adjusting the horizontal heights of the first working mechanism 2 and the second working mechanism 3. The setting of the hand wheel 615 makes the rotation of the lifting screw 612 more convenient, thereby improving the user experience of consumers. It should be noted that the setting of the hand wheel 615 is used to provide convenience for consumers to drive the lifting screw 612. Under the same effect, the hand wheel 615 can also be replaced by a cross bar.

[0041] Furthermore, the lifting screw 612 is also provided with a gear 616, and the gear 616 is fixedly connected to the lifting screw 612, so that the lifting screw 612 and the gear 616 can drive each other to rotate; at the same time, the gears 616 on the lifting screws 612 in the plurality of lifting devices 61 are connected by a transmission belt 617. When in use, as long as the lifting screw 612 in one lifting device 61 is driven to rotate, under the action of the transmission belt 617 and the gear 616, the lifting screws 612 in the remaining lifting devices 61 can all rotate synchronously, thereby achieving the purpose of synchronous lifting of the lifting devices 61;

[0042] Therefore, in actual installation, a plurality of the lifting devices 61 are respectively arranged at different positions at the bottom of the first working mechanism 2 and the second working mechanism 3, and the first working mechanism 2 and the second working mechanism 3 can be lifted and lowered in a balanced manner through the synchronous lifting and lowering of the lifting devices 61, thereby improving the lifting and lowering stability of the first working mechanism 2 and the second working mechanism 3;

[0043] Preferably, the transmission belt 617 may be a chain or a belt, and the chain and the belt are meshed and transmission-connected with the gear 616;

[0044] Furthermore, the frame 1 is further provided with a plurality of tension wheels 15, the tension wheels 15 are wound and connected with the transmission belt 617, and the tension wheels 15 are used to adjust the tightness of the transmission belt 617, thereby improving the adjustment and lifting sensitivity of the first working mechanism 2 and the second working mechanism 3;

[0045] Preferably, in order to further improve the lifting sensitivity and lifting balance of the first working mechanism 2 and the second working mechanism 3, the gear 616 and the tensioning wheel 15 in each lifting device 61 are at the same horizontal height.

[0046] Specifically, at least one guide column 16 is provided at the bottom of each of the first working mechanism 2 and the second working mechanism 3, and a guide sleeve 17 corresponding to the guide column 16 is fixedly connected to the frame 1. When in use, the guide column 16 is inserted into the guide sleeve 17. The coordinated arrangement of the guide column 16 and the guide sleeve 17 has a guiding effect on the lifting and lowering adjustment of the first working mechanism 2 and the second working mechanism 3, thereby improving the lifting and lowering stability of the first working mechanism 2 and the second working mechanism 3.

[0047] Specifically, Figure 10-11 As shown, the cutter mechanism 12 includes an upper knife assembly 121, a lower knife assembly 122 and a cutter drive assembly 123. The upper knife assembly 121 and the lower knife assembly 122 are arranged correspondingly up and down, and the rear ends of the two are hinged to each other to form a "C"-shaped structure. The cutter drive assembly 123 is movably connected to the upper knife assembly 121 and the lower knife assembly 122 respectively. Under the drive of the cutter drive assembly 123, the front ends of the upper knife assembly 121 and the lower knife assembly 122 can be moved away from or close to each other in the vertical direction, thereby completing the sealing and cutting operation of the cutter mechanism 12 on the film 4;

[0048] Further, the upper knife assembly 121 includes an upper knife holder 1211 and a sealing knife 1212, and the sealing knife 1212 is arranged at the bottom of the upper knife holder 1211; the lower knife assembly 122 includes a lower knife holder 1221 and a knife groove 1222, and the knife groove 1222 is arranged at the top of the lower knife holder 1221; the sealing knife 1212 and the knife groove 1222 are both "L"-shaped structures and are arranged correspondingly up and down; by controlling the cutter drive assembly 123, the front ends of the upper knife assembly 121 and the lower knife assembly 122 are controlled to move away from or approach each other, thereby achieving the purpose of controlling the opening and closing of the sealing knife 1212 and the knife groove 122, and realizing the sealing and cutting of the front end and the side end of the film 4 on the second working mechanism 3;

[0049] Furthermore, the cutter drive assembly 123 includes a connecting shaft 1231, a balance bar 1232, a swing bar 1233, a cutter cylinder 1234, a long connecting rod 1235 and a short connecting rod 1236. The connecting shaft 1231 is horizontally rotatably connected to the frame 1. One end of the connecting shaft 1231 is fixedly connected to the balance bar 1232, and the other end is fixedly connected to one side of the swing bar 1233. One end of the swing bar 1233 is rotatably connected to the output end of the cutter cylinder 1234, and the other end of the cutter cylinder 1234 is rotatably connected to the frame 1. Under the telescopic action of the cutter cylinder 1234, the swing bar 1233 is pushed to swing, thereby controlling the rotation of the connecting shaft 1231 and the swing of the balance bar 1232.

[0050] The two ends of the balance bar 1232 are rotatably connected to one end of the long connecting rod 1235 and the short connecting rod 1236 respectively, and the other end of the long connecting rod 1235 is rotatably connected to the upper knife holder 1211, and the other end of the short connecting rod 1236 is rotatably connected to the lower knife holder 1221; by controlling the swing of the balance bar 1232, under the action of the upper supporting force or the downward pulling force of the long connecting rod 1235 and the short connecting rod 1236, the front ends of the upper knife assembly 121 and the lower knife assembly 122 can be moved away from or close to each other; therefore, in actual application, the expansion and contraction of the cutting knife cylinder 1234 is controlled to control the opening and closing of the sealing knife 1212 and the knife groove 1222 to achieve the purpose of sealing and cutting the film 4.

[0051] Specifically, Fig. 9As shown, a receiving mechanism 14 is further provided at the bottom of the second working mechanism 3, and the receiving mechanism 14 includes a receiving motor 141 and a receiving wheel 142. One end of the receiving motor 141 is fixedly connected to the frame 1, and the output shaft (not shown) of the receiving motor 141 is connected to the axis of the receiving wheel 142. When in use, the sealed and cut film 4 is wound around the receiving wheel 142, and the receiving motor 141 drives and drives the receiving wheel 142 to rotate, so that the film 4 is continuously wound around the receiving wheel 142 to collect waste materials;

[0052] Furthermore, the rotation speed of the receiving wheel 142 matches the film drawing speed of the film drawing mechanism 32 .

[0053] Specifically, Figure 1 As shown, the frame 1 is also provided with a control console 13, and the control console 13 is electrically connected to the first transport mechanism 21, the second transport mechanism 31, the film feeding mechanism 11, the film pulling mechanism 32, the cutting mechanism 12 and the material receiving mechanism 14 respectively, and the control console 13 is used to regulate the operation and mutual coordination between the various mechanisms.

[0054] The following is a detailed description of the working principle of the utility model;

[0055] When in use, the film 4 is firstly arranged on the first transport mechanism 21 and the second transport mechanism 31, and is synchronously moved in the same direction with the first transport mechanism 21 and the second transport mechanism 31 under the pulling of the film-pulling mechanism 32, and the product 5 is placed on the first transport mechanism 21 and then moved into the film 4 on the second transport mechanism 31, and is wrapped by the film 4. At this time, the first transport mechanism 21, the second transport mechanism 31 and the film-pulling mechanism 32 all stop operating, and the upper knife assembly 121 and the lower knife assembly 122 synchronously approach each other up and down and perform "L"-shaped sealing and cutting on the film 4, and then the first transport mechanism 21, the second transport mechanism 31 and the film-pulling mechanism 32 all resume operation to continue to transport the next product 5; the sealed and cut film 4 of the product 5 is tightly attached to the outer surface of the product 5 after heat shrinkage, and the consumer can observe the position of the sealing and cutting line 43 on the film 4;

[0056] When the sealing and cutting line 43 is too high or too low, the horizontal heights of the first working mechanism 2 and the second working mechanism 3 are adjusted by the lifting mechanism 6; during adjustment, the hand wheel 615 on the lifting device 61 is rotated to drive all the lifting devices 61 to rise and fall synchronously, and the relative heights of the first working mechanism 2 and the second working mechanism 3 and the cutter mechanism 12 are quickly adjusted, thereby achieving the purpose of adjusting the sealing and cutting line 43.

[0057] The innovation of the utility model lies in that by setting a lifting mechanism, the first working mechanism and the second working mechanism can be synchronously adjusted in horizontal height relative to the cutter mechanism, thereby adjusting the sealing and cutting line position of the product film; at the same time, by turning a hand wheel in a lifting device, the synchronous lifting and lowering of multiple lifting devices in the lifting mechanism can be achieved, and the adjustment is fast and convenient, which is conducive to consumers to quickly calibrate the sealing and cutting line position, thereby achieving the effect of beautifying the product film packaging.
