[0028] The cup body supporting device and the filling machine of the utility model will be described below in combination with Figures 1-4 The cup body supporting device and the filling machine of the utility model.

[0029] As Figure 1 Indicated, the cup body supporting device 100 provided by the embodiments of the utility model comprises a template 11, a supporting block 12 and an adjusting part 13. The plurality of supporting blocks 12 are annularly distributed, the supporting block 12 is installed on the template 11, the end of the plurality of supporting blocks 12 away from the template 11 is surrounded to form a supporting part, and the supporting part is used for supporting the cup rim 31 of the cup body 300. The plurality of adjusting parts 13 and the plurality of supporting blocks 12 are one-to-one corresponding, the adjusting part 13 is connected between the supporting block 12 and the template 11, and is used for adjusting the distance of the end of the supporting block 12 away from the center of the annular, so that the supporting part is expanded or reduced.

[0030] It can be understood that the supporting part formed by the end of the plurality of supporting blocks 12 away from the template 11 has an opening with the size matched with the cup rim 31 of the cup body 300. When the cup body 300 is placed in the supporting part, the cup body 300 is arranged in the opening, and the plurality of supporting blocks 12 support the cup body 300 at a plurality of point positions in the circumferential direction of the cup rim 31. Optionally, the plurality of supporting blocks 12 are circularly arrayed, and correspondingly, the end of the plurality of supporting blocks 12 away from the template 11 is combined to form a plurality of supporting point positions in circular array, thereby forming uniform and stable support in the circumferential direction of the cup body 300.

[0031] The plurality of supporting blocks 12 are arranged in a ring shape, and the adjusting member 13 is used to adjust the distance between the end of the supporting block 12 away from the mold plate 11 and the center of the ring shape, so that the supporting part is expanded or reduced, that is, the aperture of the opening of the supporting part is increased or reduced. In this way, the size of the supporting part can be adjusted by the adjusting member 13 to adapt to cup bodies 300 of different specifications and sizes.

[0032] In the embodiment, the position of the supporting block 12 on the mold plate 11 can be adjusted by the adjusting member 13 along the radial direction of the bearing part, so that the plurality of supporting blocks 12 are away from or close to each other, and the size of the opening of the supporting part is adjusted. Alternatively, the supporting block 12 is rotationally connected to the mold plate 11, and the adjusting member 13 is used to adjust the included angle between the supporting block 12 and the mold plate 11, so that the end of the plurality of supporting blocks 12 away from the mold plate 11 is away from or close to each other, and the size of the opening of the supporting part is adjusted.

[0033] The cup body supporting device provided by the embodiment of the utility model, through setting supporting block 12 and adjusting member 13 on mold plate 11, using the supporting part formed by the ring shape arrangement of the plurality of supporting blocks 12 to support the cup rim 31 of cup body 300, adjusting the distance between the end of supporting block 12 away from the mold plate and the center of the ring shape by adjusting member 13, so that the supporting part is expanded or reduced to adapt to cup body 300 of different specifications and sizes, improve the versatility of cup body supporting device, reduce the warehouse management pressure and investment cost of mold. When switching products in production, it is not necessary to replace and install the cup holder, mold plate and filling machine, but only to adjust the size of the supporting part on the currently used cup body supporting device, so that the disassembly and assembly time and the waste of labor for replacing the mold are reduced, and the production efficiency is improved.

[0034] In the embodiment of the utility model, the mold plate 11 is provided with a through hole 111, and the plurality of supporting blocks 12 are arranged around the through hole 111. When the cup body 300 is supported by the plurality of supporting blocks 12, the cup body 300 can pass through the through hole 111, so that the size of the supporting block 12 can be designed to be more compact, and the structure of the cup body supporting device can be more compact.

[0035] Optionally, the mold plate 11 is provided with a plurality of through holes 111. As shown in Figure 1 The plurality of through holes 111 are arranged along a straight line at intervals. Each through hole 111 is provided with a plurality of supporting blocks 12, so that the cup body supporting device can be used to support a plurality of cup bodies 300 at the same time.

[0036] Referring to Figure 3 In the case that the supporting block 12 is rotationally connected to the mold plate 11, the push mechanism 200 located below the mold plate 11 can pass through the through hole 111 to push the plurality of supporting blocks 12, so that the plurality of supporting blocks 12 are away from each other, which is used to release the cup body 300 and prevent the cup body 300 from being stuck, so that the cup body 300 can be smoothly transferred between processes.

[0037] As shown in Figure 2As shown, in the embodiment of the utility model, the adjusting piece 13 comprises a sliding block 131 and a limiting piece 132. The sliding block 131 is connected to the template 11 along the radial direction of the supporting part, and the supporting block 12 is connected to the sliding block 131. The limiting piece 132 is connected between the sliding block 131 and the template 11, and is used for limiting the distance between the sliding block 131 and the supporting part along the radial direction of the supporting part. The radial direction of the supporting part is the radial direction of the opening of the supporting part, that is, the radial direction of the through hole 111.

[0038] In some embodiments, the supporting block 12 can be slidably installed on the template 11 through the sliding block 131, and the sliding block 131 is slid along the radial direction of the supporting part to drive the supporting block 12 to move, so that the plurality of supporting blocks 12 are moved away from or close to each other, and the size of the opening of the supporting part is adjusted. When the size of the supporting part needs to be adjusted, the positions of the plurality of sliding blocks 131 are first slid along the radial direction of the supporting part, and then the positions of the sliding blocks 131 are limited by the limiting piece 132, so that the size adjustment and fixation of the supporting part are completed.

[0039] In some other embodiments, the supporting block 12 is rotatably connected to the template 11, and the sliding of the sliding block 131 relative to the template 11 can drive the supporting block 12 to rotate relative to the template 11. The supporting block 12 is elastically connected to the sliding block 131 in the rotating direction of the supporting block 12.

[0040] Specifically, the cup supporting device 100 further comprises a connecting seat 141 and a rotating shaft 142. The two connecting seats 141 are arranged on the two sides of the sliding direction of the sliding block 131, and the rotating shaft 142 is connected between the two connecting seats 141. The supporting block 12 is sleeved on the rotating shaft 142 and can rotate relative to the rotating shaft 142.

[0041] The sliding block 131 can overcome or release the elastic force between the sliding block 131 and the supporting block 12 when the sliding block 131 slides, and can drive the supporting block 12 to rotate, so as to change the included angle between the supporting block 12 and the template 11, and make the plurality of supporting blocks 12 away from or close to each other at one end away from the template 11, so as to adjust the size of the opening of the supporting part.

[0042] In the process of driving the supporting block 12 to rotate by the sliding block 131, the sliding block 131 will be deformed under the extrusion of the supporting block 12, and when the sliding block 131 is fixed by the limiting piece 132, the supporting block 12 can be stabilized at a specific angle, and only when subjected to a large enough external force can the supporting block 12 rotate. After the external force disappears, the supporting block 12 can return to the specific angle under the action of the elastic force. For example, the plurality of supporting blocks 12 are pushed away from each other by the pushing mechanism 200 passing through the through hole 111, and after the pushing mechanism 200 is withdrawn, the supporting blocks 12 return to the original state under the action of the elastic force.

[0043] In the embodiment of the utility model, the structure that can provide elastic force between the supporting block 12 and the sliding block 131 can be independent of the two, such as a torsion spring; it can also be the part of the structure of the supporting block 12 and the sliding block 131 that contacts each other. For example, the part of the sliding block 131 that contacts the supporting block 12 is an elastic part, and the sliding block 131 is connected with the supporting block 12 through the elastic part. Alternatively, the sliding block 131 is an elastic member as a whole. Optionally, the sliding block 131 is a silica gel member or an elastic plastic member.

[0044] Specifically, the sliding block 131 is an elastic member, the sliding block 131 is provided with a groove, and the groove has a first groove wall 1311 and a second groove wall 1312. The first groove wall 1311 is close to the supporting part, and the second groove wall 1312 is away from the supporting part. The bottom of the supporting block 12 is pressed between the first groove wall 1311 and the second groove wall 1312.

[0045] Optionally, the first groove wall 1311 and the second groove wall 1312 are connected to form a "V"-shaped groove, and the bottom of the supporting block 12 is provided with a "V"-shaped part that is matched with the shape of the "V"-shaped groove. When the sliding block 131 slides towards the direction close to the supporting part, the sliding block 131 extrudes one side of the "V"-shaped part through the second groove wall 1312 to make the supporting block 12 rotate, and the opening of the supporting part is enlarged. When the sliding block 131 slides away from the supporting part, the sliding block 131 extrudes the other side of the "V"-shaped part through the first groove wall 1311 to make the supporting block 12 rotate in the opposite direction, and the opening of the supporting part is reduced. After the position of the sliding block 131 is determined, the supporting block 12 is stabilized at a specific angle under the action of the "V"-shaped groove, and only when a large enough external force is applied can the supporting block 131 rotate.

[0046] It should be noted that the groove on the sliding block 131 is not limited to the structure of the "V"-shaped groove described above, as long as it can push the supporting block 12 to rotate and can provide elastic force in the rotating direction of the supporting block 12.

[0047] The sliding connection mode of the sliding block 131 and the template 11 in the embodiment of the utility model can have multiple forms. For example, Figure 1 and Figure 2 As shown in some optional embodiments, the template 11 is provided with a guide groove 112, the guide groove 112 is arranged along the radial direction of the supporting part, and a plurality of sliding blocks 131 are arranged one by one in a plurality of guide grooves 112 to guide the sliding of the sliding blocks 131 through the guide grooves 112. The guide groove 112 can be a through groove that penetrates the template 11, or a blind groove arranged on the upper surface of the template 11.

[0048] In other optional embodiments, the above-mentioned guide groove 112 can be replaced by a guide boss protruding from the template 11, and the sliding block 131 is guided and connected with the guide boss.

[0049] The limiting member 132 in this embodiment of the present invention can have various structural forms. For example, the limiting member 132 is a screw, and the template 11 has multiple positioning holes arranged radially along the support portion for each slider 131. The slider 131 is connected and fixed to the template 11 by a screw passing through one of the positioning holes, and the position of the slider 131 can be adjusted by changing the positioning hole that mates with the screw.

[0050] like Figure 2 As shown in the embodiment of this utility model, the limiting member 132 is installed at the bottom of the template 11. The limiting member 132 is provided with a limiting groove 1321, and the bottom of the slider 131 is provided with a limiting protrusion 1313, which is limited within the limiting groove 1321. Specifically, the template 11 is provided with a guide groove 112 that penetrates the template 11. The slider 131 also has a sliding part 1314 connected to the limiting protrusion 1313, which is slidably disposed within the guide groove 112.

[0051] In some embodiments, the limiting member 132 is a disc-shaped member, and the limiting member 132 has a plurality of limiting grooves 1321 arranged radially along the support portion for each slider 131, and the limiting protrusion 1313 is located in one of the limiting grooves 1321. The position of the slider 131 can be adjusted by changing the limiting groove 1321 that mates with the limiting protrusion 1313.

[0052] In other embodiments, such as Figure 4 As shown, the limiting protrusions 1313 of the multiple sliders 131 are inserted one-to-one into the multiple limiting grooves 1321. The limiting grooves 1321 are arranged to extend around the support portion and away from the support portion, and the rotation angle of the limiting member 132 relative to the axis of the support portion is adjustable. The axis of the support portion is the axis of the opening of the support portion.

[0053] Specifically, the limiting member 132 is a disc-shaped member, and the limiting member 132 has the same number of limiting grooves 1321 as the slider 131. The limiting grooves 1321 extend in a direction surrounding the support part on one hand, and also extend away from the support part on the other hand. The projection of the limiting groove 1321 toward the template 11 and the projection of the guide groove 112 toward the template 11 have an overlapping portion, and the slider 131 corresponds to this overlapping portion. The groove wall of the limiting groove 1321 corresponding to the overlapping portion limits the limiting protrusion 1313.

[0054] Since the rotation angle of the limiting member 132 relative to the supporting portion is adjustable, the position of the part where the limiting groove 1321 coincides with the projection of the guide groove 112 can be changed by rotating the limiting member 132, so as to adjust and fix the position of the slider 131 in the radial direction of the supporting portion. In the embodiment, the rotation of the limiting member 132 is used to simultaneously act on the plurality of sliders 131, so as to simultaneously adjust the positions of the plurality of sliders 131, which makes the adjustment of the opening size of the supporting portion simpler and faster, shortens the adjustment time, and improves the production efficiency.

[0055] Optionally, the limiting groove 1321 is an arc-shaped groove, and the concave side of the arc shape faces the supporting portion. In this way, the normal thrust of the limiting groove 1321 on the slider 131 is along the sliding direction of the slider 131, so that the rotation of the limiting member 132 is smoother, and the phenomenon of jamming during the rotation adjustment of the limiting member 132 is avoided.

[0056] Optionally, the limiting member 132 is further provided with a fixing groove 1322, and the plurality of fixing grooves 1322 surround the supporting portion and extend in the surrounding direction of the supporting portion. The limiting member 132 is fixedly installed with the template 11 through a fixing member penetrating the fixing groove 1322. Optionally, the fixing member is a screw. The fixing member penetrating the fixing groove and the position relative to the template 11 can be fixed, and the rotation adjustment of the limiting member 132 can be performed only by loosening the screw without disassembling the screw, so that the adjustment of the opening size of the supporting portion is simple and convenient.

[0057] The cup supporting device 100 is arranged at the moving end of the moving mechanism. The moving mechanism is used to drive the cup supporting device 100 to flow between a plurality of work stations.

[0058] Further, as shown in the cup supporting device 100 is arranged at the moving end of the moving mechanism. The moving mechanism is used to drive the cup supporting device 100 to flow between a plurality of work stations. Figure 3 Further, as shown in the cup supporting device 100 is arranged at the moving end of the moving mechanism. The moving mechanism is used to drive the cup supporting device 100 to flow between a plurality of work stations.

[0059] The jacking mechanism 200 is fixed at a specific workstation. The jacking mechanism 200 includes a driving member 22 and a jacking plate 21. The driving member 22 drives the jacking plate 21 to reciprocate axially in the through hole 111. A jacking portion 211 protrudes from the jacking plate 21. Optionally, the jacking portion 211 can be an annular cylindrical structure. Optionally, multiple jacking portions 211 protrude from the jacking plate 21, with each jacking portion 211 corresponding to one of the multiple through holes 111. The driving member 22 can be a linear drive such as a linear cylinder or hydraulic cylinder.

[0060] like Figure 4 As shown, when the driving member 22 drives the push plate 21 to move upward, multiple push parts 211 simultaneously pass through multiple through holes 111, pushing the multiple support blocks 12 corresponding to each through hole 111 to open outward to the second angle position, thereby releasing the cup body 300 and facilitating process flow. When the driving member 22 drives the push plate 21 to move downward, after the push parts 211 separate from the support blocks 12, each support block 12 returns to the first angle position under the action of elasticity.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
