Description

Technical Field

[0001] The utility model relates to the technical field of cake cup processing devices, in particular to a cake cup side wall pattern processing and fixing mechanism. Background Art

[0002] A cake cup is a cup-shaped structure used to hold cake batter. It can be roughly divided into paper cake cups, iron cake cups, etc. according to the material.

[0003] Among them, the outer wall of the iron cake cup generally has corresponding patterns at equal intervals. The patterns can increase the overall aesthetics on the one hand, and on the other hand, they can increase the friction coefficient of the outer wall of the cake cup. When users take the cake cup with heat-insulating gloves or clamping parts, they can ensure that the cake cup is under control.

[0004] Therefore, iron cake cups are generally provided with a plurality of patterns on the circumference of the side wall to ensure that the user can directly contact the patterns. Therefore, in the actual processing, in order to reduce the complexity of the operating device, a corresponding mechanism needs to be set to drive the cake cup to rotate, so that a single processing device can process at multiple points.

[0005] The prior art devices generally clamp and fix the cake cup by means of a clamping member, and drive the clamping member to rotate as a whole by setting a corresponding mechanism to realize the rotation of the cake cup. However, since the clamping member is in direct contact with the outer wall of the cake cup, in practice, the operator needs to pay extra attention to the relationship between the clamping position and the processed position to avoid the clamping member hindering the processing.

[0006] Therefore, we believe that a processing and fixing mechanism is needed that can achieve a limiting and fixing effect inside the cake cup and can drive the cake cup to rotate. Summary of the invention

[0007] In view of the deficiencies in the prior art, the utility model proposes a mechanism for fixing the pattern processing on the side wall of a cake cup, which has the advantage of achieving positioning inside the cake cup and avoiding occupying the space on the outer wall of the cake cup to hinder processing. It solves the disadvantages of the prior art device that the outer wall of the cake cup is clamped and fixed, and the operator needs to make adjustments to avoid hindering processing, which is time-consuming and laborious.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A driving motor is coaxially arranged on the upper end of the driving gear, and the driving motor is fixedly connected to the positioning plate, and the output shaft of the driving motor is coaxially fixedly connected to the driving gear.

[0014] Preferably, the transmission ratio between the driving gear and the driven gear is not equal to one, and the outer diameter length of the driven gear is greater than the outer diameter length of the driving gear.

[0015] Preferably, the telescopic rod comprises an outer tube and an inner rod, the lower end surface of the inner rod is fixedly connected to the support plate, the upper end of the inner rod is embedded in the outer tube, a tension spring is sleeved on the outer side of the inner rod, and the other axial end of the tension spring is fixedly connected to the outer tube.

[0016] Preferably, a screw is coaxially fixedly connected to the upper end face of the outer tube, a through hole is opened on the positioning plate for the screw, and the screw is inserted into the through hole, the upper end of the screw is threadedly connected to a limiting nut, and the lower end face of the limiting nut abuts against the upper end face of the positioning plate.

[0018] Preferably, a plurality of balls are embedded in the upper end of the support plate, and the balls abut against the cake cups.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The utility model can change the relative distance between the damping pad and the fixed tube by sliding the movable rod up and down, that is, change the spacing between the damping pad and the inner wall of the cake cup. This makes it possible for the device to utilize the interference fit between the damping pad and the inner wall of the cake cup to realize position constraint of the cake cup during actual use.

[0021] The utility model realizes the process of taking and placing the cake cup by moving the positioning plate up and down. When the positioning plate is moved down, the movable plate can be moved down synchronously to increase the length of the movable rod embedded in the fixed tube and reduce the distance between the damping pad and the inner wall of the cake cup, which can reduce the operation steps.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Please refer to Figure 1-5 A cake cup side wall pattern processing and fixing mechanism comprises a support plate 2, a cake cup 5 is placed above the support plate 2, and the support plate 2 is used to support and limit the cake cup 5.

[0031] A driving mechanism 1 is provided below the support plate 2. The driving mechanism 1 is used to change the inclination angle of the support plate 2, that is, to change the inclination angle of the cake cup 5 placed above the support plate 2, which can facilitate the processing of the pattern.

[0032] A limiting mechanism 4 is provided above the support plate 2, through which the position of the cake cup 5 can be constrained to ensure that the cake cup 5 always coincides with the central axis of the support plate 2, and that the cake cup 5 does not shift during processing.

[0033] Specifically, the limiting mechanism 4 includes a plurality of telescopic rods 401 fixedly connected to the support plate 2 and evenly arranged around the central axis of the support plate 2. The telescopic rod 401 includes an outer tube 4011 and an inner rod 4013. The inner rod 4013 is embedded in the outer tube 4011 to achieve the purpose of changing the length of the telescopic rod 401.

[0034] The multiple telescopic rods 401 are axially aligned up and down and the central axis of the telescopic rods 401 coincides with the upper end surface of the support plate 2, so that the positioning plate 404 located above the multiple telescopic rods 401 and fixedly connected to the multiple telescopic rods 401 can change the relative distance between it and the support plate 2 as needed.

[0035] A fixed tube 406 is coaxially arranged at the lower end of the positioning plate 404 , and a movable rod 411 is embedded at the lower end of the fixed tube 406 . The movable rod 411 is slidably connected to the fixed tube 406 , and the movable rod 411 can make vertical linear motion relative to the fixed tube 406 .

[0036] The side end surfaces of the fixed tube 406 and the movable rod 411 are circumferentially provided with a plurality of U-shaped grooves 417, and the plurality of U-shaped grooves 417 on the fixed tube 406 and the movable rod 411 correspond one to one, and a limit rod 410 is rotatably connected in each U-shaped groove 417, so that each limit rod 410 rotatably connected to the fixed tube 406 can find a corresponding limit rod 410 rotatably connected to the movable rod 411 on the same vertical plane.

[0037] Therefore, by constraining the near ends of the two limit rods 410 in the same vertical plane to rotate, the projection length of a single limit rod 410 on the horizontal plane can be changed during the process of sliding the movable rod 411 up and down, that is, the relative distance between the near ends of the two limit rods 410 in the same vertical plane and the fixed tube 406 can be changed, that is, the present device can achieve the limiting fixation of the cake cup 5 by controlling the limit rod 410 to abut against the inner wall of the cake cup 5.

[0038] Furthermore, the device is provided with a plurality of damping pads 407 on the inner side of the cake cup 5, and the constraint damping pads 407 correspond one-to-one to the U-shaped grooves 417, and the damping pads 407 are rotatably connected to the corresponding limiting rods 410 through the fixing plate 409 at one end close to the fixed tube 406. This can not only realize the rotatable connection of the two limiting rods 410 in the same vertical plane, but also avoid the limiting rods 410 from directly contacting the inner wall of the cake cup 5 and causing damage. At the same time, the damping pads 407 are made of rubber material, which can further enhance the friction between the limiting mechanism 4 and the cake cup 5, thereby enhancing the limiting constraint effect on the cake cup 5.

[0039] Furthermore, as shown in the figure, the lower end of the positioning plate 404 is rotatably connected to the fixed tube 406 via a bearing. This makes it possible to drive the limiting rod 410 through the positioning plate 404 to realize the rotation process of the cake cup 5 in practice, which helps to change the processing position of the cake cup 5 and thus reduce the processing time.

[0040] Furthermore, the longitudinal section of the movable rod 411 constrained by the present device is an I-shaped structure, and a positioning ring 416 is sleeved on the outer side of the smaller diameter portion of the middle section of the movable rod 411. The positioning ring 416 is embedded in the lower end of the fixed tube 406 and fixedly connected to the fixed tube 406, which can constrain the movement trajectory of the movable rod 411, thereby ensuring that the movable rod 411 and the fixed rod cannot be separated.

[0041] At the same time, in order to avoid the relative rotation between the movable rod 411 and the fixed rod due to the gap, the damping pad 407 is twisted, so that the rotation range of the cake cup 5 does not meet the requirements. The device is fixedly connected with a positioning rod 414 at the upper end of the positioning ring 416, and a positioning groove 415 is opened on the upper end of the movable rod 411 with a larger diameter for the positioning rod 414 to constrain the positioning rod 414 to be inserted into the positioning groove 415, so as to ensure that the movable rod 411 can be driven to rotate by the positioning rod 414 during the rotation of the fixed tube 406, thereby avoiding the relative rotation between the movable rod 411 and the fixed tube 406.

[0042] Furthermore, the device has a compression spring 412 coaxially fixedly connected to the lower end face of the positioning ring 416, which constrains the lower end face of the compression spring 412 to be fixedly connected to the larger diameter portion of the lower end of the movable rod 411. This ensures that under normal circumstances, the portion of the movable rod 411 embedded in the fixed tube 406 is sufficiently small. This ensures that under normal circumstances, the distance between the damping pad 407 and the fixed tube 406 is sufficiently small, thereby facilitating the insertion of the damping pad 407 into the interior of the cake cup 5.

[0043] Specifically, the device is provided with a driven gear 408 coaxially sleeved on the outer side of the upper end of the fixed tube 406, and a driving gear 413 is meshingly connected to one side of the driven gear 408. The driving gear 413 drives the driven gear 408 and then drives the fixed tube 406 to realize the rotation process of the cake cup 5.

[0044] A driving motor 405 is disposed at the upper end of the driving gear 413 , and the automatic rotation process of the driving gear 413 is realized by coaxially and fixedly connecting the output shaft of the driving motor 405 with the driving gear 413 .

[0045] The driving motor 405 is fixedly connected to the positioning plate 404 .

[0046] Furthermore, the transmission ratio between the driving gear 413 and the driven gear 408 is not equal to one, and the outer diameter length of the driven gear 408 is greater than the outer diameter length of the driving gear 413, that is, the rotation speed of the driven gear 408 is less than the rotation speed of the driving gear 413. This can not only reduce the requirements for the driving motor 405, but also make the rotation amplitude of the cake cup 5 more precise, which is more helpful to control the rotation amplitude of the cake cup 5.

[0047] Furthermore, in order to reduce the resistance encountered by the cake cup 5 during rotation and reduce the load on the driving motor 405, the device is embedded with a plurality of balls 3 at the upper end of the support plate 2 to reduce the resistance encountered by the cake cup 5 through the balls 3.

[0048] It should be noted that, in practice, the device controls the distance between the lower end surface of the movable rod 411 and the support plate 2 by changing the length of the telescopic rod 401. Therefore, during use of the device, it is first necessary to lift the movable rod 411 and place the cake cup 5 under the movable rod 411. Then, the length of the telescopic rod 401 is reduced until the movable rod 411 abuts against the inner wall of the lower end of the cake cup 5, and the movable rod 411 is embedded in the fixed tube 406 and the length increases. At this time, the distance between the damping pad 407 and the fixed tube 406 increases, and the damping pad 407 and the cake cup 5 are fixed by interference fit.

[0049] Therefore, in this device, a tension spring 4012 is sleeved on the outside of the inner rod 4013, and the two axial ends of the tension spring 4012 are respectively fixedly connected to the outer tube 4011 and the support plate 2, which can realize the automatic falling process of the movable rod 411.

[0050] Furthermore, the upper end surface of the outer tube 4011 is fixedly connected with an upper axial screw 403, and the positioning plate 404 is provided with a through hole for the screw 403, and the screw 403 is inserted into the through hole, and the upper end of the screw 403 is threaded with a limiting nut 402, and the lower end surface of the limiting nut 402 abuts against the upper end surface of the positioning plate 404, which can fully restrict the height of the positioning plate 404 and fully ensure that the damping pad 407 can generate a large friction force with the cake cup 5.

[0051] In actual use, the utility model:

[0052] First, the operator pulls the positioning plate 404 upwards. At this time, the tension spring 4012 accumulates elastic potential energy, and the movable rod 411 is embedded in the fixed tube 406 to a minimum length.

[0053] Then, the cake cup 5 is placed under the movable rod 411. At this time, the positioning plate 404 is released, the tension spring 4012 releases elastic potential energy, the lower end surface of the movable rod 411 abuts against the inner wall of the cake cup 5, and the compression spring 412 accumulates elastic potential energy;

[0054] Afterwards, the rotating limit nut 402 further lowers the height of the positioning plate 404. At this time, the movable rod 411 is embedded in the fixed tube 406 to increase its internal length, and the damping pad 407 fully abuts against the side wall of the cake cup 5, so that the cake cup 5 is coaxial with the support plate 2.

[0055] Finally, as the processing progress changes, the driving motor 405 is controlled to start, driving the cake cup 5 to rotate and change the processing position.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
