The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment takes the reciprocating mold box assembly 100 of the ZB418 type packaging machine as an example, and the reciprocating mold box assembly 100 includes a moving plate 110 and a sleeve 120, a side folder 140, a bottom folder 130, a cam 1 132 and a cam 2 142 installed on the moving plate 110. Among them, the reciprocating assembly includes two sleeves 120, and each sleeve 120 is provided with two side folders 140 and a bottom folder 130. The side folders 140 matched with the same sleeve 120 are located at the same end of the sleeve 120. Correspondingly, the reciprocating mold box assembly 100 includes three cams 132 and two cams 2 142, and the two side folders 140 located on the two outer sides correspond to a cam 1 132 to drive them respectively; the two side folders 140 located in the middle are driven by a cam 1 132. Each cam 2 142 drives a corresponding bottom folder 130 to move.

[0025] The side folder 140 includes a side swing arm and a side folding sheet 141. The side folding sheet 141 is provided with an oblong hole. The side folding sheet 141 is fixed to the side swing arm through the oblong hole and the side connecting screw. Therefore, the side folder adjustment part 153 is a side connecting screw and an oblong hole. The position of the side folder 140 can be adjusted by adjusting the connection position of the side connecting screw and the oblong hole. The ZB418 packaging machine reciprocating mold box assembly 100 is a prior art, and the remaining structure is not described here.

[0026] like Figure 4 As shown, an adjustment tool 200 of a reciprocating mold box assembly 100 of a tobacco device in an embodiment of the present invention includes an adjustment platform 210 and at least three cam tracks. The at least three tracks are arranged on the adjustment platform 210, and respectively include at least two plane curve tracks 221 adapted to cam one 132 and at least one side curve track 222 adapted to cam two 142. The plane curve track 221 is used to adjust the opening degree of the side folder 140, and the side curve track 222 is used to adjust the opening degree of the bottom folder 130; the cam track includes at least a first pause position and a second pause position; the first pause position is used to adjust the verticality of the bottom folder 130 and the bottom wall 122 of the sleeve, and the second pause position is used to adjust the height of the bottom folder 130 and the bottom wall 122 of the sleeve.

[0027] like Figure 1-4As shown, specifically, the adjustment fixture 200 adapted to the reciprocating mold box assembly 100 of the ZB418 packaging machine includes five cam tracks, three of which are plane curve tracks 221 adapted to the cam 1 132, and two are side curve tracks 222 adapted to the cam 2 142. When the reciprocating mold box assembly 100 is debugged on the adjustment fixture 200, the cam 1 132 and the cam 2 142 need to be placed into the corresponding cam tracks. The reciprocating mold box assembly 100 is manually driven to move along the adjustment fixture 200 in the front-back direction, and the cam 1 132 and the cam 2 142 are driven by the curved cam track side edges to drive the bottom folder 130 and the side folder 140 to open or close. In this way, the state of the reciprocating mold box assembly 100 when it is running in the equipment can be reproduced on the adjustment fixture 200. It should be noted that the cam track includes a first pause position and a second pause position, each of which corresponds to the corresponding state of the reciprocating mold box assembly 100 running in the device, and the corresponding components in the reciprocating mold box assembly 100 can be corrected. Specifically, at the first pause position, the bottom folding piece 131 needs to be perpendicular to the bottom wall 122 of the sleeve; at the second pause position, the upper edge of the bottom folding piece 131 needs to be at a predetermined height from the bottom wall 122 of the sleeve. It should be noted that the plane curved track 221 and the side curved track 222 can be directly set in correspondence with the actual running track in the device where the reciprocating mold box assembly is located, or the track in the actual device can be partially reproduced at the key position. It is only necessary to ensure that the first pause position and the second pause position of the cam track correspond to the corresponding state of the reciprocating mold box assembly 100 running in the device.

[0028] like Figure 1-4 As shown, preferably, in order to ensure that the reciprocating mold box assembly 100 can move in the front-to-back direction, the adjustment fixture 200 is also arranged with a linear guide rail 230 in the front-to-back direction, and a linear track slider 231 for fixing the reciprocating mold box assembly 100 is slidably arranged on the linear guide rail 230. In this embodiment, there are two sets of linear guide rails and linear track sliders 231, which are symmetrically arranged on the left and right sides of the adjustment platform 210. When the reciprocating mold box assembly 100 is adjusted by using the adjustment platform 210, after the cam 1 132 and the cam 2 142 are respectively extended into the corresponding cam guide rails, the moving plate 110 can be fixed on the linear track slider 231, and then the reciprocating mold box assembly 100 is pushed to a predetermined position.

[0029] like Figure 4As shown, preferably, the adjustment tool 200 also includes a positioning block for positioning the reciprocating mold box assembly 100 to the first pause position or the second pause position. In the present embodiment, the positioning block includes a rotatable first positioning block 240 and a rotatable second positioning block 241 mounted on the adjustment platform 210, and the first positioning block 240 and the second positioning block 241 are rectangular blocks of different lengths, respectively, and are arranged in front of the linear track slider 231, for abutting the corresponding linear track slider 231, thereby realizing the positioning of the first pause position and the second pause position. Wherein, the length of the above-mentioned rectangular block refers to the length of the rectangular block in the front-to-back direction when the first positioning block 240 or the second positioning block 241 is used to abut against the linear track slider 231.

[0030] like Figure 1-3 As shown, under normal circumstances, the parameters that need to be adjusted for the reciprocating mold box assembly 100 are the width of the sleeve 120, that is, the distance between the two side walls of the sleeve 120; when the reciprocating mold box assembly 100 is located at the first pause position, the verticality of the bottom folder 130 and the bottom wall 122 of the sleeve, that is, the verticality of the bottom folding piece 131 and the bottom wall 122 of the sleeve; when the reciprocating mold box assembly 100 is located at the second pause position, the relative height of the bottom folder 130 and the bottom wall 122 of the sleeve, that is, the relative height of the upper edge of the bottom folding piece 131 and the bottom wall 122 of the sleeve; and the relative position of the side folder 140 and the bottom folder 130, that is, the distance in the left-right direction between the facing end faces of the side folders 140 located on both sides of the same sleeve 120 and the side edges of the bottom folding piece 131 adjacent to the end face is greater than or equal to the second predetermined width W2. It should be noted that, since the position of the sleeve 120 and the corresponding bottom folding piece 131 is determined and both are bilaterally symmetrical structures, and the corresponding two side folders 140 are symmetrically distributed on both sides of the common symmetry plane of the sleeve 120 and the bottom folding piece 131, the relative position of the side folder 140 and the bottom folder 130 can be directly converted into the relative position of the side folder 140 and the sleeve 120. That is, the adjustment of the second predetermined width W2 can be converted into adjusting the distance between the facing side edges of the two side folding pieces 141 to be at least greater than or equal to the second predetermined distance D.

[0031] like Figure 1-5As shown, preferably, the adjustment tool 200 also includes a first standard module 300. When the first standard module 300 is placed in the sleeve 120, the end faces close to the two side walls are parallel to each other and the distance between the two end faces is the first predetermined width W1. In this embodiment, the first standard module 300 is a cuboid, and the width of the cuboid is equal to the width of the sleeve 120. When adjusting the width of the sleeve 120, the standard module is placed in the sleeve 120, and the sleeve side walls 121 are pressed against the outer side walls of the first standard module 300 through the sleeve width adjustment 150, so as to adjust the distance between the sleeve side walls 121 to the first predetermined width W1.

[0032] Of course, the first standard module 300 in the shape of a rectangular parallelepiped can also be used to adjust the verticality of the bottom folding piece 131 and the bottom wall 122 of the sleeve. Specifically, the reciprocating mold box assembly 100 is adjusted and pushed to the first pause position, the first standard module 300 is placed in the sleeve 120, and the rear end face of the first standard module 300 is flush with the rear side edge of the sleeve 120, and the bottom folder vertical adjustment part 151 is operated to make the end face of the bottom folding piece 131 facing the sleeve 120 close to the corresponding rear end face of the first standard module 300, and then the bottom folding piece 131 is adjusted to be perpendicular to the bottom wall 122 of the sleeve.

[0033] When adjusting the relative height between the upper edge of the bottom folding sheet 131 and the bottom wall 122 of the sleeve, for example, when the predetermined height is 0, first drive the reciprocating mold box assembly 100 to the second stop position, place the first standard module 300 or an object with a smooth straight surface, such as a steel ruler, in the sleeve 120, with the smooth straight surface facing downward, so that the rear end of the first standard module 300 or the steel ruler extends out of the sleeve 120 from the rear side, and operate the bottom folder height adjustment part 152 so that the upper edge of the bottom folding sheet 131 abuts against the smooth straight surface, and fix the bottom folding sheet 131. Of course, if the predetermined height is non-zero data, for example, when silver foil paper needs to be folded, a ruler can be used to determine the height between the upper edge of the bottom folding sheet 131 and the bottom wall 122 of the sleeve.

[0034] like Figure 1-6 As shown, when adjusting the relative position of the side folder 140 and the bottom folder 130, the reciprocating mold box assembly 100 can be pushed to move in the front-rear direction of the adjustment tooling 200, and the distance between the opposite side edges of the side folding sheets 141 can be measured. It is only necessary to ensure that the distance between the opposite side edges of the folding sheets 141 at any position is at least greater than or equal to the second predetermined distance D, thereby avoiding mutual interference between the bottom folder 130 and the side folder 140 when the reciprocating mold box assembly 100 is working normally (that is, when folding the liner paper).

[0035] Preferably, the adjustment tool 200 also includes a second standard module 310, the second standard module 310 includes a second standard module part one 311 and a second standard module part two 312, the second standard module part one 311 can be placed in the sleeve 120; the distance between the left side of the second standard module part one 311 and the left side of the second standard module part two 312 and the distance between the right side of the second standard module part one 311 and the right side of the second standard module part two 312 are both equal to the second predetermined distance D. Therefore, when adjusting the relative positions of the side folder 140 and the bottom folder 130, the reciprocating mold box can be pushed to move forward and backward on the adjustment tooling 200, and any position where the folding pieces 141 on both sides are opened wider can be selected to adjust the side folder adjustment part 153 to ensure that the second standard module part 311 can be placed in the sleeve 120 and the left and right outer sides of the second standard module part 311 are respectively attached to the inner side of the sleeve 120, and the facing side edges of the corresponding side folding pieces 141 respectively abut against the left and right sides of the corresponding second standard module part 2 312.

[0036] like Figure 1-Figure 6 As shown, accordingly, the present invention also proposes an embodiment of a method for adjusting a reciprocating mold box assembly 100 of a tobacco equipment, which applies the above-mentioned adjustment tooling 200, including the following steps: S1, placing the reciprocating mold box assembly 100 on the adjustment tooling 200, placing the cam 1 132 in the corresponding plane curve track 221, and placing the cam 2 142 on the side curve track 222 accordingly, operating the sleeve opening width adjustment part 150, and adjusting the distance between the two side walls of the sleeve opening 120 to a first predetermined width W1; S2, sliding the reciprocating mold box assembly 100 along the front-to-back direction to a first pause position, operating the bottom folder vertical adjustment part 151, and adjusting the bottom folding The stacking sheet 131 is adjusted to a position perpendicular to the bottom wall 122 of the sleeve; S3, the reciprocating mold box assembly 100 is slid along the front-to-back direction to the second pause position, the bottom folder height adjustment part 152 is adjusted, and the upper end edge of the bottom folding sheet 131 is adjusted to a predetermined height relative to the bottom wall 122 of the sleeve; S4, the reciprocating mold box assembly 100 is placed on the adjustment fixture 200, the cam 1 132 is placed in the corresponding plane curve track 221, and the cam 2 142 is placed on the side curve track 222 accordingly, and the side folder adjustment part 153 is operated to adjust the distance between the two opposite side edges of the side folding sheet 141 to be greater than or equal to the second predetermined distance D.

[0037] After the various parameters of the reciprocating die box assembly 100 are adjusted, the reciprocating die box assembly 100 is directly assembled back into the original tobacco equipment, so that the reciprocating die box assembly 100 can work normally in the tobacco equipment.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
