Description

Technical Field

[0001] This utility model relates to the field of plastic bottle processing technology, and in particular to a tilting unloading mechanism and a blow molding machine. Background Technology

[0002] Automated unloading of sesame oil bottles generally faces the problem of insufficient bottle posture stability. For example, traditional unloading mechanisms typically use a single clamping component to grip the bottle and then release it directly onto the conveyor belt. When the clamping component releases the bottle, it only contacts the conveyor belt through the bottom of the bottle, lacking lateral restraint. This makes the bottle prone to tilting due to inertia or vibration, potentially leading to tipping. Furthermore, adding a second gripper to fix the bottle body and / or mouth at the clamping component not only poses a risk of spatial movement interference, but also means the bottle still only contacts the conveyor belt through its bottom, thus not fundamentally eliminating the original risk of tipping. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a tilting unloading mechanism and a blow molding machine to solve the technical problem of the risk of bottle tipping in the traditional unloading mechanism in the related technology.

[0004] This utility model provides a tilting unloading mechanism for automatic unloading of bottles, wherein the bottle has a body and a mouth, and the tilting unloading mechanism includes:

[0005] Work surface;

[0006] A first mounting base is slidably disposed on the operating table surface along a first direction;

[0007] A flip-grip assembly includes a flipping part and a clamping part. The flipping part is rotatably disposed on the first mounting base about an axis arranged in a second direction. The clamping part is connected to the flipping part so as to be flipped by the flipping part. The clamping part has a deformable clamping space for clamping or releasing the bottle mouth located in the clamping space.

[0008] The second mounting base is fixed to the operating table and located at the end of the sliding path of the first mounting base. The second mounting base forms a conveying space for conveying the bottle along the second direction.

[0009] A positioning component is slidably disposed on the second mounting base along a first direction, for positioning or releasing the bottle body located in the conveying space;

[0010] The clamping part and the positioning component are staggered and spaced apart along a third direction, and any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0011] Furthermore, the clamping part includes at least one set of clamping blocks, each set of clamping blocks having multiple clamping blocks, the multiple clamping blocks being arranged to gradually approach and move away from each other, and forming a deformable clamping space therebetween.

[0012] Furthermore, the clamping part also includes a support column, the clamping block is movably disposed on the support column, and the support column has a through hole for connecting the flipping part.

[0013] Furthermore, the flipping part includes a rotating shaft extending along a second direction, the rotating shaft passing through the through hole.

[0014] Furthermore, the rotating shaft is provided with a plurality of first limiting protrusions and a plurality of second limiting protrusions on opposite sides along the first direction, and the plurality of first limiting protrusions and the plurality of second limiting protrusions are arranged in a one-to-one correspondence for alternating contact with the support column.

[0015] Furthermore, the positioning component includes at least one positioning block, the positioning block having a positioning notch, the open end of the positioning notch being positioned toward the conveying space.

[0016] Furthermore, the cross-section of the positioning notch is an arc-shaped structure.

[0017] Furthermore, the second mounting base is provided with a stop block, which is close to the conveying space and is positioned opposite to the positioning notch.

[0018] This utility model also provides a blow molding machine, including the above-described tilting unloading mechanism.

[0019] Compared with the prior art, this utility model has the following advantages: the first mounting base slides back and forth along the first direction, and the second mounting base is located at the end of the sliding path of the first mounting base, so that the blow-molded bottle can be clamped and transferred to the conveying space of the second mounting base using the clamping component at the first mounting base; at the same time, the rotation axis of the flipping part is set along the second direction, and can drive the clamping part to flip, and the conveying space can also convey the bottle along the second direction, which not only achieves the purpose of fast and automated unloading, but also prevents spatial interference and facilitates installation and maintenance; furthermore, the clamping part The positioning component is staggered along a third direction, so that when the bottle is released into the conveying space, the clamping part can use its clamping force to form a temporary lateral constraint on the bottle mouth, while the positioning component slides along the first direction to the middle of the bottle body to provide radial clamping force, thus forming a composite constraint mode of dual-point limiting. Through the staggered arrangement of the clamping part and the positioning component, the center of gravity of the bottle is always located in the polygonal support area formed by the bottom contact surface of the bottle, the lateral constraint point of the clamping part, and the radial clamping point of the positioning component.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0028] In the embodiments of this utility model, such as Figure 1As shown, the flipping unloading mechanism includes: an operating table 1, a first mounting base 2, a flipping clamping assembly 3, a second mounting base 4, and a positioning assembly 5; the first mounting base 2 is slidably disposed on the operating table 1 along a first direction; the flipping clamping assembly 3 includes a flipping part and a clamping part, the flipping part is rotatably disposed on the first mounting base 2 about an axis set along a second direction, the clamping part is connected to the flipping part so as to be flipped by the flipping part, the clamping part has a deformable clamping space for clamping or releasing the bottle mouth located in the clamping space; the second mounting base 4 is fixed to the operating table 1 and located at the end of the sliding path of the first mounting base 2, the second mounting base 4 forms a conveying space for conveying the bottle body along the second direction; the positioning assembly 5 is slidably disposed on the second mounting base 4 along the first direction for positioning or releasing the bottle body located in the conveying space; wherein, the clamping part and the positioning assembly 5 are offset and spaced apart along a third direction, and any two of the first direction, the second direction, and the third direction are perpendicular to each other.

[0029] Specifically, in this embodiment of the invention, the bottle body includes a bottle mouth, a bottle body, and a bottle bottom connected sequentially. An operating table 1 is provided at the outlet of the blow molding machine. The operating table 1 has a length direction and a width direction. A slide rail is provided along the length direction of the operating table 1, and a first mounting seat 2 is slidably disposed on the slide rail. Simultaneously, a second mounting seat 4 is fixed to the end of the sliding path of the first mounting seat 2, allowing the first mounting seat 2 to slide relative to the second mounting seat 4, moving closer to or away from the second mounting seat 4. Therefore, the length direction of the operating table 1 is defined as the first direction in this embodiment, and its width direction as the second direction. When this mechanism is installed, the first mounting seat 2 is positioned closer to the outlet of the blow molding machine, and the second mounting seat 4 is positioned closer to the external conveyor belt.

[0030] In this embodiment of the invention, a flipping part and a clamping part are connected at the first mounting base 2. The flipping part can rotate 180° around an axis set along the second direction, so that the clamping part on it rotates in conjunction with it. In addition, the clamping space formed by the clamping part can change its internal dimensions, thereby using the clamping part to clamp the bottle mouth, and finally using the flipping part to quickly transfer the bottle from the outlet of the blow molding machine. Of course, in order to further prevent the clamping part from interfering with the movement of the bottle, the first mounting base 2 mentioned above can include two mounting parts, namely: the lower mounting part is slidably mounted on the operating table 1 by means of a slide rail, and the upper mounting part is used to install the flipping part and the clamping part. The upper and lower mounting parts are connected by a cylinder, which can be raised and lowered along the third direction. The upper mounting part can move relative to the lower mounting part, thereby changing the distance between the flipping part, the clamping part and the bottle at the outlet. Combined with the fact that the lower mounting part can slide along the second direction, it can prevent movement interference and reduce the assembly precision of the mechanism.

[0031] In this embodiment of the present invention, a positioning component 5 is provided at the second mounting base 4. The positioning component 5 is arranged opposite to the flip clamping component 3 in the first direction and can slide back and forth in the first direction, so that the positioning component 5 can position the bottle body. During unloading, the first mounting base 2 is located at the beginning of its sliding path. The clamping part clamps the bottle mouth in the clamping space. Then, the flipping part flips in conjunction with the first mounting base 2 and slides towards its end to place the bottle body in the conveying space of the second mounting base 4. At this time, the positioning component 5 slides towards the conveying space to position the bottle body. In this process, the clamping part can use its clamping force to form a temporary lateral constraint on the bottle mouth, while the positioning component 5 slides along the first direction to the middle of the bottle body to provide radial clamping force, forming a composite constraint mode of double-point limiting. Through the staggered arrangement of the clamping part and the positioning component 5, the center of gravity of the bottle is always located in the polygonal support area formed by the bottom contact surface of the bottle, the lateral constraint point of the clamping part, and the radial clamping point of the positioning component 5. Compared with the traditional single-point support, it can effectively reduce the risk of bottle tipping and improve the stability of the bottle body in the conveying space.

[0032] In this embodiment, as Figure 1 As shown, the first direction is defined as being set along the left and right, the second direction is defined as being set along the front and back, and the third direction is defined as being set along the up and down; and the flipping part, the clamping part, and the positioning component 5 all have a moving state and a reset state to form a continuous automated unloading mode.

[0033] In this embodiment, the cooperation between the first mounting base 2 and the flipping clamping assembly 3 enables the bottle body at the outlet of the blow molding machine to be quickly transferred to the conveying space of the second mounting base 4. Since a conveyor belt can be installed in this conveying space, the bottle body can be continuously and automatically conveyed to the next process, improving the automation efficiency of the equipment. At the same time, the clamping part and the positioning assembly 5 are arranged in a staggered manner along the same direction, which allows the clamping part to clamp the bottle mouth, the positioning assembly 5 to be positioned at the bottle body, and the bottom of the bottle to abut against the conveying space to form a three-point support system. Compared with single-point support, this can ensure the stability of the bottle body in the conveying space to a greater extent and prevent the bottle from tipping over.

[0034] like Figure 2As shown, in one embodiment, the clamping part includes at least one set of clamping block groups, each set of clamping block groups having multiple clamping blocks 302. These multiple clamping blocks 302 are arranged to gradually approach and move away from each other, forming a deformable clamping space. Specifically, to clamp or release the bottle neck, this embodiment uses multiple movable clamping blocks 302. The gradual approach or movement of the multiple clamping blocks 302 changes the size of the clamping space formed therebetween, facilitating the formation of a gripping shape to clamp and release the bottle neck. Of course, to improve operational efficiency, the clamping part may include multiple sets of clamping block groups spaced apart along a second direction, with at least two clamping blocks 302 forming a group for simultaneously clamping different bottles. Figure 3 As shown, this embodiment uses two clamping blocks 302 as a group to clamp and release the bottle mouth. Each clamping block 302 has an L-shaped structure with a serrated structure at its vertical end. The horizontal ends of the two clamping blocks 302 are hinged and pulled by a driving structure (e.g., a cylinder), allowing each clamping block 302 to rotate around its respective hinge point (as shown in Figure 3, the hinge point is located at the connection between the horizontal and vertical ends of the clamping block 302, and the hinge point is located in the housing). Thus, under the drive of the driving structure, the opening formed by the two clamping blocks 302 can gradually decrease or increase, thereby changing the size of the clamping space to facilitate clamping or releasing the bottle mouth.

[0035] like Figure 2 As shown, in one embodiment, the clamping part further includes a support column 303, the clamping block 302 is movably disposed on the support column 303, and the support column 303 forms a through hole for connecting the flipping part. Specifically, in order to connect the flipping part and the clamping part, this embodiment provides a support column 303, one end of which is connected to the housing, and the other end forms a through hole for the flipping part to rotate. Of course, the number of the aforementioned support columns 303 can be increased or decreased according to the number of clamping block groups to ensure that all components are synchronized and coordinated. Preferably, the flipping part includes a rotating shaft 301 extending along the second direction, the rotating shaft 301 passing through the through hole and driven by a motor disposed on the first mounting base 2.

[0036] Furthermore, such as Figure 2As shown, in one embodiment, the rotating shaft 301 is provided with a plurality of first limiting protrusions 6 and a plurality of second limiting protrusions 7 on opposite sides along a first direction. The plurality of first limiting protrusions 6 and the plurality of second limiting protrusions 7 are arranged in a one-to-one correspondence for alternating contact with the support column 303. Specifically, the rotating shaft 301 can drive each clamping block 302 to rotate via the support column 303. Since the outlet of the blow molding machine and the conveying space of the second mounting base 4 are located on opposite sides of the first mounting base 2, in order to ensure that the clamping part can rotate 180°, not only is the cooperation of a series of driving devices such as motors and reducers required, but also the provision of first limiting protrusions 6 and second limiting protrusions 7 on opposite sides along a first direction of the rotating shaft 301, so that the support column 303 can alternately contact the first limiting protrusions 6 and the second limiting protrusions 7 when it rotates, thus playing a role in limiting and supporting. Of course, the number of limiting protrusions can be set to multiple to form multiple points of force.

[0037] like Figure 4 As shown, in one embodiment, the positioning component 5 includes at least one positioning block 501. The positioning block 501 has a positioning notch 502, the open end of which faces the conveying space. Specifically, for positioning the bottle body, this embodiment defines the positioning component 5 as including a positioning block 501, with a positioning notch 502 provided at the positioning block 501, and the opening direction of the positioning notch 502 facing the conveying space. Thus, the positioning block 501 is slidably disposed on the second mounting base 4 and can move closer to or further away from the conveying space. When it is close to the conveying space, it can use the positioning notch 502 to clamp the bottle body, providing stable support. Conversely, when the positioning block 501 gradually moves away from the conveying space, it can release the bottle body without obstruction, so that the bottle body can be smoothly conveyed out. Preferably, to adapt to the shape of the bottle body, the cross-section of the positioning notch 502 in this embodiment is an arc-shaped structure.

[0038] like Figure 1 As shown, in one embodiment, the second mounting base 4 is provided with a stop 8, which is close to the conveying space and is positioned opposite to the positioning notch 502. Specifically, when the bottle is located in the conveying space, in order to avoid the large asynchronous movement range between the clamping block 302 and the positioning block 501, which could cause the bottle to slide out of the conveying space or tip over or tilt, this embodiment provides a stop 8 at the second mounting base 4. The stop 8 is arranged along the second direction and is positioned opposite to the positioning notch 502, which can block the bottle in case of a malfunction.

[0039] This embodiment also provides a blow molding machine, including the above-described tilting unloading mechanism. The specific structure of the unloading mechanism is as described in the above embodiment. Since this blow molding machine adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
