Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a packaging machine pallet structure. Background Technology

[0002] Oral liquid medicines, such as Codonopsis pilosula oral liquid and cough syrup, are filled into vials after production. After filling and sealing, multiple vials need to be individually placed into the slots of a blister tray. Existing vial loading devices (such as the ampoule labeling machine disclosed in application number 201120166703.3) complete the vial loading work through slots on a dial wheel. However, this dial wheel has a good loading effect for vials of a certain length, and its application range is narrow. When the vial is short, it is easy for the vial to move along the axis of the dial wheel in the slot, which makes it difficult for the vial to be successfully placed into the tray, resulting in poor loading effect. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a packaging machine tray structure to solve the technical problems of existing technology where the dial cannot tray vials within a certain length range, has a narrow application range, and has a poor traying effect for shorter vials.

[0004] To achieve the above technical objectives, the present invention provides a packaging machine tray structure for traying vials, comprising:

[0005] A loading mechanism includes a housing and a rotating wheel. The housing has a cavity, and the housing has an inlet and an outlet that communicate with the cavity. The rotating wheel is rotatably and sealed within the cavity. The outer wall of the rotating wheel has multiple grooves that extend along its axial direction. During the rotation of the rotating wheel, the opening of each groove communicates with the inlet or outlet in sequence.

[0006] The adjustment mechanism includes multiple adjustment plates, each of which is slidably disposed in a corresponding groove and can move along the length of the groove to adjust the length of the bottling area.

[0007] Furthermore, the mounting mechanism also includes a rotation drive assembly connected to the rotating wheel for driving the rotating wheel to rotate.

[0008] Furthermore, each end of the housing has a slot communicating with the cavity. The slots are circular and coaxial with the cavity. The wheel includes a wheel body and two shafts. The wheel body is rotatably and sealed within the cavity. Each groove is formed on the outer side wall of the wheel body. The two shafts are tubular structures and are respectively located at both ends of the wheel body. One end of each shaft is coaxially fixed to the wheel body, and the other end of each shaft rotatably passes through the corresponding slot and extends out of the housing. The rotation drive assembly is connected to one of the shafts and is used to drive the corresponding shaft to rotate.

[0009] Furthermore, the rotation drive assembly includes a driven wheel, a driving wheel, a conveyor belt, and a first rotation drive member. The driven wheel is disposed outside the housing and fixedly sleeved on one of the rotating shafts. The end face of the driven wheel near the housing abuts against the housing. The driving wheel is disposed to the side of the driven wheel. The conveyor belt has a closed structure and is wound around the driven wheel and the driving wheel. The output end of the first rotation drive member is coaxially fixed to the driving wheel and is used to drive the driving wheel to rotate.

[0010] Furthermore, the adjustment mechanism also includes a motion drive component, which is connected to each of the adjustment plates and is used to drive each of the adjustment plates to move synchronously along the length direction of the groove.

[0011] Furthermore, the rotating wheel has a guide channel extending along its axial direction and coaxial with it. The rotating wheel also has multiple connecting channels extending along its axial direction. One side of each connecting channel communicates with the guide channel, and the other side of each connecting channel communicates with a corresponding groove. The moving drive assembly includes a first screw, a bushing, multiple connecting rods, and a first handwheel. The first screw is coaxial with the rotating wheel. One end of the first screw is disposed within the guide channel and rotatably connected to the rotating wheel. The other end of the first screw rotatably passes through the rotating wheel and the housing and extends outside the housing. The bushing is slidably disposed within the guide channel. The bushing has a first screw hole and is sleeved onto the first screw via the first screw hole. The first screw hole is screwed to the first screw. Each connecting rod is slidably disposed within a corresponding connecting channel. One end of each connecting rod is fixedly connected to the bushing, and the other end of each connecting rod is fixedly connected to a corresponding adjusting plate. The first handwheel is disposed outside the housing and fixedly connected to the other end of the first screw.

[0012] Furthermore, the opening width of the groove gradually increases from the inside to the outside.

[0013] Furthermore, the packaging machine palletizing structure also includes two conveying mechanisms, which are respectively located on the side and below the housing. The outlet end of the conveying mechanism located on the side of the housing is connected to the bottle inlet for conveying vials, and the conveying mechanism located below the housing is used for conveying trays. The conveying width of the conveying mechanisms is adjustable.

[0014] Furthermore, the conveying mechanism includes two side plates, a conveyor belt, a reciprocating drive assembly, a limiting plate, and a limiting adjustment assembly.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This utility model provides a tray-loading structure for packaging machines, used for traying vials, the structure of which is as follows: Figure 1 - Figure 5As shown, the device includes a loading mechanism 100 and an adjusting mechanism 200. The loading mechanism 100 includes a housing 110 and a rotating wheel 120. The housing 110 has a cavity 111, and the housing 110 has an inlet 112 and an outlet 113 communicating with the cavity 111. The rotating wheel 120 is rotatably disposed within the cavity 111. The outer wall of the rotating wheel 120 has multiple grooves 121 extending axially. During the rotation of the rotating wheel 120, the opening 114 of each groove 121 communicates sequentially with the inlet 112 or the outlet 113. The adjusting mechanism 200 includes multiple adjusting plates 210, each of which is slidably disposed within a corresponding groove 121 and can move along the length of the groove 121 to adjust the length of the bottling area.

[0026] In use, the inlet 112 is connected to the outlet of the upstream processing step. Based on the length of the vial, the length of the filling area within each groove 121 is pre-adjusted. Each adjusting plate 210 is then sequentially manipulated, causing each adjusting plate 210 to move along the length of its corresponding groove 121. This allows adjustment of the length of the filling area within each groove 121. After filling and sealing, the vial reaches the inlet 112 of the housing 110 in a horizontal position. During the rotation of the rotating wheel 120, the openings 114 of each groove 121 sequentially connect with either the inlet 112 or the outlet 113. When the opening 114 of the groove 121 connects with the inlet... When 112 is connected, the vial enters the bottling area in the groove 121 and is transported to the outlet 113 as the roller 120 rotates. The vial is discharged along the outlet 113 and falls into the tray. This tray structure can adjust the length of the bottling area in the groove 121 on the roller 120 according to the length of the vial, so that the roller 120 has a good transport and traying effect for vials within a certain length range, and has a wide range of applications. The axial movement of the vial is limited by the adjusting plate 210 and the side wall of the housing 110 to prevent the vial from moving axially in the groove when the roller 120 is transporting a shorter vial, ensuring that the vial can be smoothly loaded into the tray and improving the traying effect.

[0027] As a preferred embodiment, please refer to Figure 1 The mounting mechanism 100 further includes a rotation drive assembly 130, which is connected to the rotating wheel 120 and is used to drive the rotating wheel 120 to rotate. When the rotation drive assembly 130 is activated, it can drive the rotating wheel 120 to rotate, thereby connecting the slots 114 of each of the grooves 121 to the inlet 112 or the outlet 113 in sequence.

[0028] As a preferred embodiment, please refer to Figure 3 The cavity 111 has a columnar structure. During the rotation of the rotating wheel 120 within the cavity 111, the cavity wall of the cavity 111 can radially limit the vial in the groove 121. The inlet 112 and the outlet 113 both extend along the axial direction of the cavity 111, thereby ensuring that the inlet 112 and the outlet 113 both extend along the length direction of the groove 121, which guarantees that the vial can smoothly enter the groove 121 through the inlet 112, or that the vial in the groove 121 can smoothly exit through the outlet 113.

[0029] As a preferred embodiment, please refer to Figure 3 and Figure 4 The housing 110 has a slot 114 at each end that communicates with the cavity 111. The slot 114 is circular and coaxial with the cavity 111. The wheel 120 includes a wheel body 122 and two shafts 123. The wheel body 122 is rotatably and sealed within the cavity 111. Each groove 121 is formed on the outer side wall of the wheel body 122. The two shafts 123 are tubular structures and are respectively located at both ends of the wheel body 122. One end of each shaft 123 is coaxially fixed to the wheel body 122, and the other end of each shaft 123 rotatably passes through the corresponding slot 114 and extends out of the housing 110. The rotation drive assembly 130 is connected to one of the shafts 123 and is used to drive the corresponding shaft 123 to rotate. The two shafts 123 are rotatably connected to the housing 110, thereby providing support for the entire wheel 120.

[0030] As a preferred embodiment, please refer to Figure 2 and Figure 5 The rotating wheel 120 also includes a limiting ring 124. The limiting ring 124 is disposed outside the housing 110 and fixedly sleeved on another rotating shaft 123. The end face of the limiting ring 124 near the housing 110 abuts against the housing 110, which can limit one side of the wheel body 122 and prevent the wheel body 122 from moving axially.

[0031] As a preferred embodiment, please refer to Figure 1The rotation drive assembly 130 includes a driven wheel 131, a driving wheel 132, a conveyor belt 133, and a first rotation drive member 134. The driven wheel 131 is disposed outside the housing 110 and fixedly sleeved on one of the rotating shafts 123. The end face of the driven wheel 131 near the housing 110 abuts against the housing 110. The driving wheel 132 is disposed to the side of the driven wheel 131. The conveyor belt 133 has a closed structure and is wound around the driven wheel 131 and the driving wheel 132. The output end of the first rotation drive member 134 is coaxially fixed with the driving wheel 132. The first rotation drive 134 is activated, and its output end rotates, driving the drive wheel 132 to rotate. Since the conveyor belt 133 is wound around the driven wheel 131 and the drive wheel 132, it can drive the driven wheel 131 to rotate. During the rotation of the driven wheel 131, it will drive the shaft 123 to rotate, thereby driving the wheel 122 to rotate.

[0032] As a preferred embodiment, please refer to Figure 4 and Figure 5 The adjustment mechanism 200 further includes a motion drive component 220, which is connected to each of the adjustment plates 210 and is used to drive each of the adjustment plates 210 to move synchronously along the length direction of the groove 121. By operating the motion drive component 220, each of the adjustment plates 210 can be driven to move synchronously along the length direction of the groove 121, thereby adjusting the length of the bottling area in each of the grooves 121 without having to move the adjustment plates 210 one by one, thus achieving high adjustment efficiency for the length of the bottling area in each of the grooves 121.

[0033] As a preferred embodiment, please refer to Figure 4 and Figure 5The rotating wheel 120 has a guide channel 125 extending along its axial direction and coaxial with it. The rotating wheel 120 also has multiple connecting channels 126 extending along its axial direction. One side of each connecting channel 126 communicates with the guide channel 125, and the other side of each connecting channel 126 communicates with the corresponding groove 121. The moving drive assembly 220 includes a first screw 221, a bushing 222, multiple connecting rods 223, and a first handwheel 224. The first screw 221 is coaxial with the rotating wheel 120, and one end of the first screw 221 is provided with… The first screw 221 is placed in the guide channel 125 and rotatably connected to the rotating wheel 120. The other end of the first screw 221 rotatably passes through the rotating wheel 120 and the housing 110 and extends out of the housing 110. The bushing 222 is slidably disposed in the guide channel 125. The bushing 222 has a first screw hole and is sleeved onto the first screw 221 through the first screw hole. The first screw hole is screwed to the first screw 221. Each connecting rod 223 is slidably disposed in its corresponding connecting channel 126. One end of each connecting rod 223... All ends are fixedly connected to the bushing 222, and the other end of each connecting rod 223 is fixedly connected to the corresponding adjusting plate 210. The first handwheel 224 is disposed outside the housing 110 and fixedly connected to the other end of the first screw 221. The guide channel 125 and each of the connecting channels 126 are opened on the wheel body 122. The other end of the first screw 221 passes through the slot 114 and extends out of the housing 110. When it is necessary to adjust the length of the bottle-filling area in each of the grooves 121, the first handwheel 224 is rotated in either the forward or reverse direction. The first screw 221 can be driven to rotate in either the forward or reverse direction. Since the first screw 221 is screwed to the bushing 222, when the first screw 221 rotates in either the forward or reverse direction, the bushing 222 can move along the length direction of the guide channel 125, and each of the connecting rods 223 can move along the length direction of the corresponding connecting channel 126. Thus, the corresponding adjusting plate 210 can be driven to move along the length direction of the corresponding groove 121 via each of the connecting rods 223, thereby increasing or decreasing the length of the bottling area in each of the grooves 121.

[0034] As a preferred embodiment, please refer to Figure 4 The opening width of the groove 121 gradually increases from the inside to the outside. When vials of different diameters are placed in the groove 121, the groove 121 can limit the radial direction of the vials to prevent them from rolling within the groove 121.

[0035] As a preferred embodiment, please refer to Figure 1 and Figure 2The packaging machine tray-loading structure further includes two conveying mechanisms 300. The two conveying mechanisms 300 are respectively disposed on the side and below the housing 110. The outlet end of the conveying mechanism 300 disposed on the side of the housing 110 is connected to the bottle inlet 112 for conveying vials. The conveying mechanism 300 disposed below the housing 110 is used to convey trays. The conveying width of the conveying mechanism 300 is adjustable. The conveying speed of the conveying mechanism 300 disposed below the housing 110 is adjusted and adapted to the rotation speed of the rotary wheel 120, so that the vials in each of the grooves 121 fall sequentially into the slots in the tray.

[0036] As a preferred embodiment, please refer to Figure 1 and Figure 2 The conveying mechanism 300 includes two side plates 310, a conveyor belt 320, a reciprocating drive assembly 330, a limiting plate 340, and a limiting adjustment assembly 350. The two side plates 310 are spaced apart and vertically arranged. The conveyor belt 320 is a closed belt and is disposed between the two side plates 310. The upper surface of the conveyor belt 320 is horizontal. The reciprocating drive assembly 330 is connected to the conveyor belt 320 and is used to drive the conveyor belt 320 to perform reciprocating motion. The limiting plate 340 is disposed above the conveyor belt 320 along the conveying direction of the conveyor belt 320 and corresponds to each of the adjusting plates 210. The position adjustment component 350 is connected to the limiting plate 340 and is used to drive the limiting plate 340 to move along the conveying direction perpendicular to the conveyor belt 320 to adjust the width of the conveying area. By adjusting the conveying width of the conveying area, vials within a certain length range can be conveyed. When it is necessary to adjust the conveying width of the conveying area, the limiting plate 340 can be driven to move along the conveying direction perpendicular to the conveyor belt 320 by operating the limiting adjustment component 350, thereby adjusting the width of the conveying area. The conveyor belt 320 and the annular reciprocating drive component 330 form a belt pulley conveying structure, which will not be described in detail in this solution.

[0037] As a preferred embodiment, please refer to Figure 2 and Figure 6The side plate 310 corresponding to the adjusting plate 210 has a second screw hole and at least one through hole. The limiting adjustment assembly 350 includes a mounting sleeve 351, an inner core, a second screw 352, at least one guide rod 353, and a second handwheel 354. The mounting sleeve 351 is fixedly connected to the outer side of the limiting plate 340. The inner core is rotatably disposed within the mounting sleeve 351. The second screw 352 is horizontally disposed. One end of the second screw 352 rotatably extends into the mounting sleeve 351 and is fixedly connected to the inner core. The other end of the second screw 352 passes through the second screw hole and is screwed into the second screw hole. Each of the guide rods 35... All three guide rods are horizontally arranged. One end of each guide rod 353 is fixedly connected to the outer side of the limiting plate 340, and the other end of each guide rod 353 slides through the corresponding through hole. The second handwheel 354 is fixedly connected to the other end of the second screw 352. When it is necessary to adjust the conveying width of the conveying area, rotating the second handwheel 354 in the forward or reverse direction can drive the second screw 352 to rotate in the forward or reverse direction. Since the second screw 352 is screwed to the side plate 310, when the second screw 352 rotates in the forward or reverse direction, the limiting plate 340 can move along the conveying direction perpendicular to the conveyor belt 320.

[0038] To better understand this utility model, the following is combined with... Figure 1 - Figure 6 The working principle of the technical solution of this utility model will be described in detail below:

[0039] In use, the inlet end of the conveying mechanism 300, located on the side of the housing 110, is connected to the outlet end of the upstream processing step. The length of the bottling area in each groove 121 is pre-adjusted according to the length of the vial. Rotating the first handwheel 224 forward or backward drives the first screw 221 to rotate forward or backward. Since the first screw 221 is screwed to the bushing 222, when the first screw 221 rotates forward or backward, the bushing 222 can move along the length of the guide channel 125, and each connecting rod 223 can move along the length of its corresponding connecting channel 126, thereby allowing... Each connecting rod 223 drives the corresponding adjusting plate 210 to move along the length direction of the corresponding groove 121, thereby increasing or decreasing the length of the bottling area within each groove 121. After filling and sealing, the vials enter the conveyor belt 320 horizontally and reach the inlet 112 of the housing 110. The first rotation drive 134 is activated, and its output end rotates, driving the drive wheel 132 to rotate. Since the conveyor belt 133 is wound around the driven wheel 131 and the drive wheel 132, it can drive the driven wheel 131 to rotate. During rotation, the rotating shaft 123 will rotate, which in turn will drive the wheel 122 to rotate. As the wheel 122 rotates, the openings 114 of each groove 121 sequentially connect with either the inlet 112 or the outlet 113. When the opening 114 of a groove 121 connects with the inlet 112, the vial enters the bottling area within the groove 121. With the rotation of the wheel 120, it is transported to the outlet 113, where it is discharged and falls into the tray. The conveying speed of the conveying mechanism 300 located below the housing 110 is adjusted to match the speed of the... The rotation speed of the rotating wheel 120 is adapted so that the vials in each of the grooves 121 fall sequentially into the slots in the tray. This traying structure can adjust the length of the bottle-filling area in the grooves 121 on the rotating wheel 120 according to the length of the vials, so that the rotating wheel 120 has a good transfer and traying effect for vials within a certain length range, and has a wide range of applications. The axial movement of the vials is limited by the adjusting plate 210 and the side wall of the housing 110 to prevent the vials from moving axially in the slots when the rotating wheel 120 is transferring vials of shorter length, ensuring that the vials can be smoothly loaded into the tray and improving the traying effect.

[0040] The packaging machine tray structure provided by this utility model has the following beneficial effects:

[0041] (1) Rotating the first handwheel 224 in the forward or reverse direction can drive the first screw 221 to rotate in the forward or reverse direction. Since the first screw 221 is screwed to the bushing 222, when the first screw 221 rotates in the forward or reverse direction, the bushing 222 can move along the length direction of the guide channel 125, and each of the connecting rods 223 can move along the length direction of the corresponding connecting channel 126. Thus, the corresponding adjusting plate 210 can be driven to move along the length direction of the corresponding groove 121 via each of the connecting rods 223, thereby increasing or decreasing the length of the bottling area in each of the grooves 121. It is not necessary to move the adjusting plate 210 one by one, and the adjustment efficiency of the length of the bottling area in each of the grooves 121 is high.

[0042] (2) The axial direction of the vial is limited by the adjustment plate 210 and the side wall of the housing 110 to prevent the vial from moving axially in the groove when the wheel 120 is transferring vials with a short length, so as to ensure that the vial can be smoothly put into the tray and improve the traying effect.

[0043] (3) This mounting structure can adjust the length of the bottling area in the groove 121 on the rotating wheel 120 according to the length of the vial, so that the rotating wheel 120 has a good transfer and mounting effect on vials within a certain length range, and has a wide range of applications.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
