Description

Technical Field

[0001] This utility model relates to the technical field of bottle manufacturing, and in particular to a preform fixing and releasing structure. Background Technology

[0002] In the pharmaceutical bottle manufacturing industry, blow molding machines are the core equipment for bottle forming. The production process requires first obtaining bottle preforms through preform forming equipment, and then transferring the preforms to the blow molding machine production line through a conveying system. Among them, the preform socket conveyor tray has become the mainstream preform conveying structure because it can realize the orderly stacking of preforms and save conveying space.

[0003] However, the existing coordination between the conveyor tray and the subsequent gripping mechanism has significant drawbacks: the gripping mechanism relies heavily on mechanical positioning or simple photoelectric detection, which is prone to inaccurate positioning due to preform posture deviations, slight vibrations of the conveyor tray, or blind spots in the sensors, failing to identify preforms that have not been gripped. Such omissions result in preform waste and require periodic manual shutdowns to clean the conveyor tray, disrupting production line continuity and reducing production efficiency. More seriously, missed preforms may collide with and damage new preforms as they circulate with the conveyor tray, or affect the accuracy of subsequent bottle forming, posing a threat to the stability and safety of bottle manufacturing.

[0019] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0021] Reference Figures 1-10 This embodiment provides a preform fixing and release structure, which is used to solve the problem of preforms being left behind and collided with new preforms during the preform production process. It includes a receiving component 100, which is a plate-shaped structure made of metal, preferably stainless steel, which has both strength and corrosion resistance. It is the direct bearing component of the preform A. It is provided with sleeves 101 that cooperate with the preform A. The number of sleeves 101 is adapted to the bearing area of ​​the receiving component 100 and is consistent with the conveying distance of the preform A on the production line.

[0022] The sleeve 101 includes a connecting seat 101a and a fixed sleeve seat 101b, which are connected by welding or high-strength bolts to ensure no loosening. The blank A can be moved vertically from top to bottom and sleeved on the outside of the sleeve seat 101b. The outer diameter of the sleeve seat 101b is slightly smaller than the inner diameter of the blank A, and the connecting seat 101a is located in the sleeve-tightening direction of the blank A. That is, when the blank A is sleeved, the connecting seat 101a can prevent the blank from moving too far downward, ensuring that the sleeve depth of all blanks A is consistent.

[0023] Furthermore, the top array of the receiving component 100 has several sets of mounting slots 102. The mounting slots 102 are circular slots with dimensions that match the connecting seat 101a. The slots are provided with threaded holes. The sleeve 101 is detachably and fixedly connected to the mounting slot 102 by bolts, which makes it easy to replace the corresponding size sleeve 101 according to different specifications of bottle preform A, thereby improving the versatility of the structure.

[0024] The receiving component 100 has a first crossbeam 103 symmetrically arranged at both ends. The first crossbeam 103 is a rectangular metal tube to enhance the load-bearing capacity. The receiving component 100 is fixedly inserted into the first crossbeam 103. The insertion point adopts a transition fit and is fixed twice by a positioning pin to ensure that there is no relative displacement between the receiving component 100 and the first crossbeam 103. This connection method corresponds to the "receiving component stationary" scenario in the linear push-release mode.

[0025] Unlike the scenario where the receiving component 100 is stationary, the receiving component 100 can rotate circumferentially. In this case, the receiving component 100 has a first crossbeam 103 symmetrically arranged at both ends. The receiving component 100 is rotatably inserted into the first crossbeam 103. A deep groove ball bearing is installed at the insertion point. The outer ring of the bearing is fixed to the first crossbeam 103, and the inner ring is engaged with the rotating shaft 104 at the end of the receiving component 100, so that the receiving component 100 can rotate around the horizontal axis. This connection method corresponds to the mode of rotating and releasing the preform A.

[0026] The preform fixing and release structure also includes an auxiliary component 200. The auxiliary component 200 is a metal structure to ensure no deformation during preform pushing. The auxiliary component 200 has through holes 201 at the corresponding positions of the sleeve post 101. The number and spacing of the through holes 201 are completely consistent with the sleeve post 101. The preform A is located in the direction of movement of the auxiliary component 200 away from the sleeve post 101, that is, the auxiliary component 200 can contact the bottle mouth position of the preform A when it moves upward. The auxiliary component 200 includes a top shell 202, a baffle 203 and a connecting lug 204. The through holes 201 are arrayed on the top shell 202. The main body of the top shell 202 is a semi-circular metal shell, which facilitates the squeezing contact with the preform A and avoids damage to the preform.

[0027] The auxiliary components 200 are arranged in parallel in several groups, and the number of groups matches the number of columns of the sleeves 101 on the receiving component 100, ensuring that each group of sleeves has a corresponding auxiliary component. In addition, the connecting ears 204 at both ends of the auxiliary component 200 are respectively connected to the second crossbeams 205. The two ends of the second crossbeams 205 are parallel to avoid the auxiliary component from shifting when it moves.

[0028] A storage space K is formed between the top shell 202 and the baffle 203. The height and width of the storage space K are slightly larger than the overall dimensions of the support 100 and the sleeve 101. The support 100 and the sleeve 101 are fitted together in the storage space K to ensure that there is no collision or interference when the support and the auxiliary parts move relative to each other, and at the same time, they play a role in dust protection.

[0029] Specifically, in the scenario where the preform A is linearly pushed and released, and the auxiliary component actively moves: the preform fixing and release structure also includes a symmetrically arranged base frame 300. The base frame 300 is an integral load-bearing structure made of high-strength carbon steel. The base frame 300 includes symmetrically arranged load-bearing plates 301. In this embodiment, the load-bearing plates 301 are preferably four pieces, symmetrically distributed in pairs to enhance the support force on the top structure. It also includes a connecting beam 302 and a bottom plate 303 fixed at both ends of the load-bearing plate 301. The connecting beam 302 is a thick metal plate. The bottom plate 303 is fixed to the ground by expansion bolts. The first crossbeam 103 is fixedly connected to the connecting beam 302 by bolts. The connection point is provided with reinforcing ribs to improve the load-bearing strength.

[0030] A drive cylinder 302a is fixedly connected to the side wall of the connecting beam 302. The drive cylinder 302a can be either a pneumatic cylinder or a hydraulic cylinder, depending on the pressure requirements of the production line. In this embodiment, a pneumatic cylinder is preferred because of its fast response speed. The connecting plate 302a-1 fixed to the end of the piston rod of the drive cylinder 302a is fixedly connected to the second crossbeam 205 by bolts. When connecting, ensure that the connecting plate 302a-1 is perpendicular to the second crossbeam 205 to avoid the drive cylinder from shifting under force. The connecting plate 302a-1 is a rectangular metal plate to increase the force-bearing area.

[0031] Furthermore, in the scenario where the preform A is linearly pushed and released, and the "receiving component actively moves": the preform fixing and release structure also includes a symmetrically arranged base frame 300. The base frame 300 has the same structure as the above base frame 300, only the connecting object is different. The base frame 300 includes a symmetrically arranged load-bearing plate 301 and a connecting beam 302 and a base plate 303 fixed at both ends. The second crossbeam 205 is fixedly connected to the connecting beam 302 by bolts, and the connection point is also provided with reinforcing ribs.

[0032] A drive cylinder 302a is fixedly connected to the side wall of the connecting beam 302. The connecting plate 302a-1 fixed to the end of the piston rod of the drive cylinder 302a is fixedly connected to the first crossbeam 103 by bolts, so as to ensure that the driving force can be smoothly transmitted to the receiving part 100 and drive it to move up and down.

[0033] Furthermore, to address the scenario where the receiving component 100 rotates circumferentially to achieve "rotational release of preform A": the preform fixing and release structure also includes a symmetrically arranged base frame 300. The base frame 300 includes a symmetrically arranged load-bearing plate 301 and a connecting beam 302 and a base plate 303 fixed at both ends. The first crossbeam 103 is fixedly connected to the connecting beam 302 by bolts. This connection provides a fixed reference for the rotational release mode.

[0034] The outer wall of the connecting beam 302 is fixedly connected to a drive cylinder 302a and a drive gear plate 302b. The drive cylinder 302a is the same model as the drive cylinder used in the linear push mode. The drive gear plate 302b is a straight gear plate made of 40Cr material with surface hardening treatment to enhance wear resistance. The connecting plate 302a-1 fixed to the end of the piston rod of the drive cylinder 302a is fixedly connected to the drive gear plate 302b by bolts. When connecting, ensure that the gear plate is parallel to the axis of the piston rod of the drive cylinder to ensure smooth linear movement of the gear plate.

[0035] A gear 104a is also fixedly sleeved on the rotating shaft 104 fixed at the end of the receiving part 100. The module and number of teeth of the gear 104a match the driving gear plate 302b. The gear 104a meshes with the driving gear plate 302b. The linear motion of the gear plate drives the gear to rotate, thereby enabling the receiving part 100 to rotate 180° around the rotating shaft 104, ensuring that the preform A falls off the sleeve column 101.

[0036] Furthermore, the drive cylinder 302a is also symmetrically provided with anti-deviation holes 302a-2. The anti-deviation holes 302a-2 are smooth holes, which can reduce friction. The connecting plate 302a-1 is symmetrically fixed with inserts 302a-3. The inserts 302a-3 are cylindrical metal rods that are clearance-fitted with the anti-deviation holes 302a-2. The inserts 302a-3 are slidably inserted into the anti-deviation holes 302a-2. This can limit the movement of the connecting plate 302a-1 to only along the axis of the drive cylinder, avoid bending of the piston rod of the drive cylinder or displacement of the components, and ensure motion accuracy.

[0037] The preform fixing and releasing structure also includes a collection box 400, which can be made of plastic or metal. In this embodiment, food-grade plastic is preferred to avoid scratching the preform. The collection box 400 is fixedly connected to the base frame 300 by a bracket. The top opening of the collection box 400 is larger than the bottom opening, and the top opening covers the area where the receiving part 100 and the auxiliary part 200 are located. The size of the top opening is preferably 100-150mm larger than the coverage area of ​​the receiving part 100 and the auxiliary part 200 to ensure that no preform is missed. At least one inner wall of the collection box 400 is inclined at an angle of 30° to 45° to ensure that the preform slides smoothly under gravity without jamming. The bottom opening can be connected to a conveying pipe to guide the preform into the centralized collection device.

[0038] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
