Description

Technical Field

[0001] This utility model relates to the field of infusion bottle production equipment, and in particular to a preform extraction device for polypropylene infusion bottle production. Background Technology

[0002] For large-volume parenteral solution manufacturers, the process of filling plastic bottles with medication in the workshop typically involves shaping polypropylene granules into preforms, then blowing the preforms into bottles. After the infusion bottles are formed, they are cleaned and the medication is filled. Previously, this was done manually, grouping several preforms together for each bottle, which was inefficient and labor-intensive. Therefore, current technology uses specialized preform-taking devices to automatically group and take multiple preforms, thereby improving production efficiency.

[0003] The drawback of the aforementioned preform taking device is that it only has one set of guide rails and sliders. The clamping mechanism is set on the slider and faces the preform. Since the clamping mechanism is long and the center of gravity is located on the side of the guide rail, it is easy for the clamping mechanism to become unstable during operation, which reduces production efficiency and may also damage the preform, affecting the quality of subsequent blow molding. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a preform taking device for the production of polypropylene infusion bottles that avoids instability in the clamping mechanism during operation, improves production efficiency, does not damage the preform, and ensures the quality of subsequent blow molding.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A preform picking device for producing polypropylene infusion bottles includes a base, a clamping mechanism, a cylinder, two guide rails, at least two sliders, and a support base. The two guide rails are arranged parallel to each other on the base and located on the side of the base. Each guide rail has at least one slider, which is slidably mounted on the guide rail. The support base is fixedly connected to the slider. The clamping mechanism includes a mounting plate and a gripper assembly. The mounting plate is slidably mounted on the support base. The gripper assembly is equidistantly arranged on the mounting plate along its length direction. The gripper assembly has a clamping area facing the preform to be picked. The cylinder is pultrusively connected to the mounting plate and drives the mounting plate to move the gripper assembly to clamp the preform to be picked.

[0007] Furthermore, the number of sliders is four, with two sliders sequentially arranged along the length of each guide rail.

[0008] Furthermore, the preform taking device for producing polypropylene infusion bottles also includes a conveyor belt, the support base includes a lower base plate and an upper base plate, the lower base plate is fixedly connected to the slider, the upper base plate is located above the lower base plate, and the conveyor belt is rotatably disposed between the lower base plate and the upper base plate.

[0009] Furthermore, the preform taking device for producing polypropylene infusion bottles also includes a motor, which is located on one side of the base and is connected to the conveyor belt. The motor drives the conveyor belt to rotate and causes the slider and the support to move along the length of the guide rail.

[0010] Furthermore, the mounting plate includes a horizontal part and two vertical parts. The horizontal part is located on one side of the guide rail and is elongated. The two vertical parts are vertically arranged on the horizontal part and are respectively located on both sides of the upper base plate. The cylinder is arranged between the two vertical parts.

[0011] Furthermore, the preform taking device for producing polypropylene infusion bottles also includes two pressing blocks, each of which is disposed at the end of the vertical part away from the horizontal part.

[0012] Furthermore, the cross-sectional shape of the pressure block is L-shaped.

[0013] Furthermore, the sliding direction of the mounting plate is perpendicular to the length direction of the guide rail.

[0014] Furthermore, the gripper assembly includes two grippers arranged opposite each other, with the gripping area formed between the two grippers.

[0015] Furthermore, the preform taking device for producing polypropylene infusion bottles also includes a mounting base, which is disposed on the support base, and the cylinder is disposed on the mounting base, with the length direction of the cylinder perpendicular to the length direction of the guide rail.

[0016] Compared with the prior art, the preform taking device for polypropylene infusion bottle production of this utility model includes a base, a clamping mechanism, a cylinder, two guide rails, at least two sliders, and a support base. The two guide rails are arranged relatively parallel to each other on the base and located on the side of the base. Each guide rail has at least one slider, which is slidably mounted on the guide rail. The support base is fixedly connected to the slider. The clamping mechanism includes a mounting plate and a gripper assembly. The mounting plate is slidably mounted on the support base. The gripper assembly is equidistantly arranged on the mounting plate along the length direction of the mounting plate. The gripper assembly has a clamping area facing the preform to be taken. The cylinder is driven by the mounting plate and drives the mounting plate to move the gripper assembly to clamp the preform to be taken.

[0017] This application sets up two sets of guide rails and sliders, and sets up a support base that is fixedly connected to the sliders. This ensures that the clamping mechanism does not directly contact the sliders, and the center of gravity of the clamping mechanism is balanced with the center of gravity of the support base. This avoids instability in the clamping mechanism during operation, improves production efficiency, does not damage the preform, and ensures the quality of subsequent blow molding. The overall structure of this application is compact, the layout is reasonable, the footprint is small, and it is easy to transport. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Figures 1-3 The present invention relates to a preform taking device for the production of polypropylene infusion bottles, comprising a base 10, two guide rails 20, at least two sliders 30, a support 40, a clamping mechanism 50, and a cylinder 60.

[0026] In this embodiment:

[0027] Two guide rails 20 are arranged parallel to each other on the base 10 and located on the side of the base 10. Each guide rail 20 has at least one slider 30, which is slidably mounted on the guide rail 20. In this embodiment, there are four sliders 30, with two sliders 30 arranged sequentially along the length of each guide rail 20, which ensures that the clamping mechanism 50 is more stable during operation.

[0028] The support base 40 is fixedly connected to the slider 30. The support base 40 includes a lower base plate 41 and an upper base plate 42. The lower base plate 41 is fixedly connected to the slider 30, and the upper base plate 42 is located above the lower base plate 41. By setting the support base 40, this application ensures that the clamping mechanism 50 does not directly contact the slider 30, and the center of gravity of the clamping mechanism 50 is balanced with the center of gravity of the support base 40, thus ensuring stability during operation.

[0029] The conveyor belt 90 is rotated between the lower base plate 41 and the upper base plate 42.

[0030] The motor 100 is located on one side of the base 10 and is connected to the conveyor belt 90. The motor 100 drives the conveyor belt 90 to rotate and drives the slider 30 and the support base 40 to move along the length of the guide rail 20.

[0031] The clamping mechanism 50 includes a mounting plate 51 and a gripper assembly 52. ​​The mounting plate 51 is slidably mounted on the support base 40. Specifically, the mounting plate 51 includes a horizontal portion 511 and two vertical portions 512. The horizontal portion 511 is located on one side of the guide rail 20 and is elongated. The two vertical portions 512 are vertically arranged on the horizontal portion 511 and are located on both sides of the upper base plate 42, respectively. In this embodiment, the sliding direction of the mounting plate 51 is perpendicular to the length direction of the guide rail 20.

[0032] The gripper assembly 52 is equidistantly arranged on the mounting plate 51 along the length direction of the mounting plate 51. The gripper assembly 52 includes two grippers 521 arranged opposite to each other, and a gripping area 522 is formed between the two grippers 521. The gripping area 522 faces the preform 110 to be picked.

[0033] The cylinder 60 is connected to the mounting plate 51 and drives the mounting plate 51 to move the gripper assembly to grip the preform 110 to be picked up. In this embodiment, the cylinder 60 is located between the two vertical parts 512, and the overall structure is reasonably laid out.

[0034] Each pressure block 70 is located at the end of a vertical portion 512 away from the horizontal portion 511. In this embodiment, the cross-sectional shape of the pressure block 70 is L-shaped. This arrangement makes the layout of the support base 40 and the clamping mechanism 50 more reasonable and ensures balance.

[0035] Mounting base 80 is mounted on support base 40, and cylinder 60 is mounted on mounting base 80. The length direction of cylinder 60 is perpendicular to the length direction of guide rail 20.

[0036] In use, the slider 30 first moves the support base 40 and the clamping mechanism 50 to a suitable position, and then the cylinder 60 drives the clamping mechanism 50 to move to clamp multiple preforms at once. In this application, by setting two sets of guide rails 20 and sliders 30, and setting a support base 40 fixedly connected to the slider 30, the clamping mechanism 50 does not directly contact the slider 30. The center of gravity of the clamping mechanism 50 is balanced with the center of gravity of the support base 40, avoiding instability of the clamping mechanism 50 during operation, improving production efficiency, preventing damage to the preforms 110, and ensuring the quality of subsequent blow molding. The overall structure of this application is compact, the layout is reasonable, the footprint is small, and it is easy to transport.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
