Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dispensing machines, in particular to a dispensing machine with a single-drive moving beam mechanism. BACKGROUND

[0002] The moving beam mechanism of the dispensing machine includes a cross beam and support structures on both sides of the cross beam. Currently, the moving beam mechanisms on the market are divided into single-drive and double-drive types. Single-drive means that a driving source (such as a driving motor) is provided on only one side of the support structure, and the moving beam mechanism moves reciprocally in a straight line. Most single-drive moving beam mechanisms currently use a design in which the driving side and the support side are symmetrical. However, since the single-drive moving beam mechanism has only one side with a power source, this symmetrical design causes the driving side and the support side of the moving beam mechanism to be unevenly stressed during movement, which easily causes the driving force to be eccentric, resulting in deformation of the cross beam. SUMMARY

[0003] The purpose of the present application is to provide a dispensing machine with a single-drive moving beam mechanism that enhances the connection rigidity of the driving side to solve the problem of uneven stress on the single-drive moving beam mechanism, which causes the cross beam to easily deform.

[0011] Further, the upper connecting block is in L shape, and a left fixed block and a right fixed block are arranged on both sides of the upper connecting block along the length direction of the support side guide rail; the left fixed block and the left connecting block have a gap, and the right fixed block and the right connecting block have a gap; the outer side walls of the left fixed block and the right fixed block are respectively provided with fixed holes, and the left connecting block and the right connecting block are respectively provided with connecting holes corresponding to the fixed holes; one end of one spring is fixed in the fixed hole of the left fixed block, and the other end is fixed in the connecting hole of the left connecting block; one end of the other spring is fixed in the fixed hole of the right fixed block, and the other end is fixed in the connecting hole of the right connecting block.

[0022] In the description of the present application, it needs to be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0023] Please refer to Figure 1 and Figure 2 The present application has a single-drive dynamic beam mechanism dispensing machine, which comprises a rack 1 and a single-drive dynamic beam mechanism 2 arranged on the rack 1. The single-drive dynamic beam mechanism 2 comprises a driving side guide rail 20, a driving side sliding block 22 and a driving side connecting assembly 24, a supporting side guide rail 30, a supporting side sliding block 32 and a supporting side connecting assembly 34, and a cross beam 40. The driving side guide rail 20 and the supporting side guide rail 30 are respectively arranged on the opposite sides of the top of the rack 1 and are parallel to each other; the driving side sliding block 22 is slidably arranged on the driving side guide rail 20, and the driving side connecting assembly 24 is fixed on the driving side sliding block 22. The supporting side sliding block 32 is slidably arranged on the supporting side guide rail 30, and the supporting side connecting assembly 34 is fixed on the supporting side sliding block 32. The cross beam 40 is located between the driving side connecting assembly 24 and the supporting side connecting assembly 34, and the opposite end faces of the cross beam 40 are fixedly connected with the driving side connecting assembly 24 and the supporting side connecting assembly 34 respectively.

[0024] Specifically, the driving side connecting assembly 24 comprises a driving side connecting plate 240 and a driving side supporting plate 242. The driving side connecting plate 240 is fixed horizontally on the driving side sliding block 22, and the driving side supporting plate 242 is fixed on the top of the driving side connecting plate 240. The driving side supporting plate 242 is fixedly connected with the first end face of the cross beam 40 on the driving side. The driving side supporting plate 242 is a trapezoidal plate, which is fixed vertically on the top of the driving side connecting plate 240 and is parallel to the driving side guide rail 20.

[0025] The supporting side connecting assembly 34 comprises a supporting side connecting piece 340 and a supporting side supporting piece 342. The supporting side connecting piece 340 is fixed on the supporting side sliding block 22; and the supporting side supporting piece 342 is fixed on the top of the supporting side connecting piece 340. The supporting side connecting piece 340 is a flat plate, which is fixed horizontally on the top of the supporting side sliding block 32; and the supporting side supporting piece 342 is fixedly connected with the second end face of the cross beam 40 on the supporting side.

[0026] The single-drive moving beam mechanism further comprises a driving motor 50, a screw rod 52 and a screw rod slider 54. The screw rod 52 is located outside the driving side guide rail 20 and parallel to the driving side guide rail 20; the driving motor 50 is connected to one end of the screw rod 52; and the screw rod slider 54 is slidably sleeved outside the screw rod 52 and fixedly connected with the driving side connecting plate 240.

[0027] When the driving motor 50 arranged at the driving side provides power to rotate the screw rod 52, the driving screw rod slider 54 moves on the screw rod 52 and conducts the driving force to the supporting side through the driving side connecting assembly 24 and the cross beam 40, so as to realize the reciprocating movement of the cross beam 40 along the driving side guide rail 20 and the supporting side guide rail 30.

[0028] However, since the single-drive moving beam mechanism 2 is in motion, the driving side and the supporting side are not evenly stressed due to the power source provided at only one side, which easily leads to the deformation of the cross beam 40. Especially when the single-drive moving beam mechanism 2 is applied to a large-stroke dispensing machine, the distance between the driving side guide rail 20 and the supporting side guide rail 30 is large, and the moving beam mechanism is in high-speed motion, which aggravates the uneven stress condition. To solve this problem, the driving side structure is improved to improve the connection rigidity of the driving side structure, and the stress point of the cross beam 40 is concentrated at the driving side, and the supporting side only plays a supporting role. Specifically,

[0029] Two driving side sliders 22 are arranged at the driving side, and the projections of the two driving side sliders 22 at the top of the rack 1 are located at both sides of the projection of the cross beam 40 at the top of the rack 1 along the length direction of the driving side guide rail 20, and only one supporting side slider 32 is arranged at the supporting side, so that the connection between the driving side connecting plate 240 and the driving side slider 22 is more firm, the connection rigidity of the driving is improved, and the supporting side only plays a supporting role. Preferably, the two driving side sliders 22 are fixedly connected with the two ends of the bottom of the driving side connecting plate 240, so as to increase the distance between the two driving side sliders 22. The greater the distance between the two driving side sliders 22, the more stable the connection between the driving side connecting plate 240 and the driving side slider 22, the stronger the rigidity of the driving side, and the more beneficial to improve the deformation of the cross beam 40 due to the uneven stress of the two sides and the eccentric driving force during the motion of the moving beam mechanism.

[0030] Furthermore, in the single-drive moving beam mechanism 2 of the present invention, the dimensions of the drive-side guide rail 20 are larger than those of the support-side guide rail 30, resulting in a larger top area for the drive-side guide rail 20 and a greater thickness for the drive-side guide rail 20 compared to the support-side guide rail 30. This increases the contact area between the drive-side guide rail 20 and the drive-side slider 22. Correspondingly, the drive-side slider 22, which slides with the drive-side guide rail 20, is also larger than the support-side slider 32, which slides with the support-side guide rail 30. Therefore, the length of the drive-side slider 22 along the drive-side guide rail 20 is greater than the length of the support-side slider 32 along the drive-side guide rail 30, resulting in a contact area between the drive-side guide rail 20 and the drive-side slider 22 that is larger than the area where the support-side guide rail 30 and the support-side slider 32 are fixedly connected. By setting drive-side guide rails and drive-side sliders with different sizes and specifications, as well as support-side guide rails and support-side sliders, the contact area between the drive-side guide rail 20 and the drive-side slider 22 is increased, that is, the force-bearing area of ​​the drive-side guide rail 20 is increased to strengthen the connection rigidity of the drive side and improve the deformation of the crossbeam 40 during the movement of the moving beam mechanism.

[0031] Furthermore, the present invention further concentrates the stress points of the crossbeam 40 on the driving side by improving the connection rigidity between the drive-side connecting assembly 24 and the crossbeam 40. Specifically, the drive-side connecting plate 240 is T-shaped, divided into a slider connecting part 240a and a crossbeam connecting part 240b. The slider connecting part 240a is perpendicular to the crossbeam connecting part 240b, and the slider connecting part 240a is fixedly connected to the top of the drive-side slider 22. The bottom half of the length of the crossbeam 40 is fixed to the crossbeam connecting part 240b of the drive-side connecting plate. Alternatively, the crossbeam connecting part 12b is a trapezoidal plate whose width gradually decreases towards the support side. The trapezoidal plate drive-side connecting plate 240 has higher strength than the T-shaped drive-side connecting plate 240; and compared to a complete square plate, it uses less material and is lighter. In this specific embodiment, the crossbeam connecting part 240b of the drive-side connecting plate 240 is a trapezoidal plate to enhance the rigidity of the drive-side connecting plate 240. Preferably, the drive-side connecting plate 240 has a hollow structure with a through groove 240c, which ensures connection rigidity while further reducing the weight of the drive-side connecting plate 240. A groove (not shown) with the same width as the crossbeam 40 along the length of the drive-side guide rail 20 is provided at the contact position between the drive-side connecting plate 240 and the crossbeam 40. The bottom of the crossbeam 40 is secured in this groove (not shown), making the connection between the crossbeam 40 and the drive-side connecting plate 240 more secure and further improving the connection rigidity between the crossbeam 40 and the drive-side connecting plate 240.

[0032] In addition, the single-drive moving beam mechanism also includes a crossbeam support 60. See also... Figure 3The crossbeam support 60 is arranged at the middle position of the back of the driving side connecting plate 240 close to the crossbeam 40, and is fixedly connected with the crossbeam 40 and the driving side connecting plate 240 respectively. Specifically, the crossbeam support 60 is in the shape of "L", comprising a first connecting part 60a and a second connecting part 60b which are connected perpendicularly with each other, the first connecting part 60a of the crossbeam support 60 is fixedly connected with the driving side connecting plate 240, and the second connecting part 60b is fixedly connected with the crossbeam 40, so that the connection between the crossbeam 40 and the driving side connecting plate 240 is more firm. Preferably, the crossbeam support 60 further comprises a support part 60c which is fixedly connected with the first connecting part 60a and the second connecting part 60b perpendicularly, so as to further improve the connection rigidity between the crossbeam 40 and the driving side connecting plate 240.

[0033] As an improved scheme of the above technical scheme, the present application realizes the elastic connection between the crossbeam 40 and the support side connecting part 342 through the support side support part 342, so as to weaken the connection rigidity between the crossbeam 40 and the support side connecting part 340. Specifically, please refer to Figures 4-6 The support side support part 342 comprises an upper connecting block 3420, a lower connecting block 3422, four screws 3424 and four springs 3426. The lower connecting block 3422 is fixedly arranged on the support side connecting part 342 horizontally; the upper connecting block 3420 is in the shape of "L", the bottom of which is fixedly arranged on the top of the lower connecting block 3422, and the rear side thereof is fixedly connected with the second end surface of the crossbeam 40 located at the support side; the upper connecting block 3420 is elastically connected with the lower connecting block 3422 through the four screws 3424 and the four springs 3426.

[0034] Specifically, the top end surface of the lower connecting block 3422 is provided with four threaded holes (not shown in the figure), and the upper connecting block 3420 is provided with four installation holes 3425 corresponding to the threaded holes (not shown in the figure) and penetrating through the upper connecting block 3420, the installation hole 3425 comprises an upper installation hole 3425a and a lower installation hole 3425b which are communicated with each other, and the inner diameter of the upper installation hole 3425a is larger than that of the lower installation hole 3425b. The four screws 3424 are partially inserted into the four installation holes respectively and are screwed into the threaded holes (only one screw 3424 is shown as an example), and the screw 3424 has a gap with the inner wall of the installation hole 3425, so that the upper connecting block 3420 can slide along the screw 3425. The four springs 3426 are arranged in the four installation holes 3425a respectively and are sleeved outside the corresponding screws 3424, the outer diameter of the spring 3426 is smaller than the inner diameter of the upper installation hole 3425a and larger than the inner diameter of the lower installation hole 3425b, and the inner diameter of the spring 3426 is smaller than the outer diameter of the head of the screw 3424. Preferably, a gasket 3423 is further sleeved between the spring 3426 and the head of the screw 3424, so as to better abut against the spring 3426 and prevent the spring 3426 from being separated from the screw 3424. Figures 4-6

[0035] ​When the single drive moving beam mechanism moves, the elastic connection between the cross beam 40 and the support side connecting piece 340 through the support side support piece 342 increases the damping in the vertical direction when the moving beam mechanism moves, and removes the reverse force generated by part of the support side connecting piece 340 on the cross beam 40 during movement, thereby improving the deformation of the cross beam 40.

[0036] Further, the upper connecting block 3420 is provided with a left fixed block 3420a and a right fixed block 3420b on both sides along the length direction of the support side guide rail 30, so as to enhance the rigidity of the upper connecting block 3420.

[0037] The support side connecting piece 342 further comprises a left connecting block 3428 and a right connecting block 3429, which are respectively detachably fixed to both sides of the lower connecting block 3422 along the length direction of the support side guide rail 30. The left connecting block 3428 has a gap between it and the left fixed block 3420a, and the right connecting block 3429 has a gap between it and the right fixed block 3420b. The outer side of the left fixed block 3420a and the right fixed block 3420b is respectively provided with two fixed holes 3421, and the left connecting block 3428 and the right connecting block 3429 are respectively provided with two connecting holes 3427 corresponding to the fixed holes 3421. One end of each of the two springs 3426 is fixed in the two fixed holes 3421 of the left fixed block 3420a, and the other end is fixed in the connecting holes 3427 of the left connecting block 3428. The other end of the other two springs 3426 is fixed in the fixed holes 3421 of the right fixed block 3420b, and the other end is fixed in the connecting holes 3427 of the right connecting block 3429, realizing the elastic connection of the upper connecting block 3420 with the left connecting block 3428 and the right connecting block 3429, so as to increase the damping in the horizontal direction when the moving beam mechanism moves. When the single drive moving beam mechanism 3 is just started and is about to stop moving, it will generate an acceleration along the direction of the support side guide rail 30 on the upper connecting block 3420 in the support side support piece 342, tending to push the upper connecting block 3420 and the lower connecting block 3422 to move relative to each other. By arranging the left connecting block 3428 and the right connecting block 3429 on both sides of the upper connecting block 3420 along the direction of the support side guide rail 30 and elastically connecting them with the upper connecting block 3420, it not only helps to remove the force generated by part of the support side connecting piece 340 on the cross beam 40 during movement, but also prevents the upper connecting block 3420 and the lower connecting block 3422 from being separated when the single drive moving beam mechanism is just started and is about to stop moving.

[0038] Compared with the prior art, the application sets different numbers of sliders on the driving side and the supporting side of the single-drive moving beam type mechanism, increases the area of the fixed connection between the driving side connecting piece and the cross beam, sets a cross beam supporting piece to strengthen the connecting rigidity of the driving side, concentrates the stress points of the cross beam on the driving side, and makes the supporting side only play a supporting role; at the same time, the elastic connection between the cross beam and the slider is realized through the supporting side supporting piece, the connecting rigidity of the supporting side structure is weakened, the difference between the connecting rigidity of the driving side structure and the connecting rigidity of the supporting side structure is further enhanced, the problem that the single-drive moving beam type mechanism is deformed due to eccentric driving force when moving because of uneven stress is solved, and the service life of the mechanism is improved. The application has the advantages of ingenious concept, simple design and strong practicability.

[0039] The above-mentioned embodiments only express several embodiments of the application, and the description is relatively specific and detailed, but it cannot be understood as the limitation of the scope of the patent right of the application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the application, and the application also intends to include these modifications and improvements.
