Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette packaging equipment technical field, concretely relates to a kind of first push chain assembly push block cross bar subassembly of ZB48A packer adjustment frock. BACKGROUND

[0002] ZB48A packer is a kind of efficient tobacco packaging equipment in tobacco industry, and its first push chain assembly is the important power transmission mechanism of ZB48A packer, and the overall length is about twenty-five meters.The first push chain assembly is composed of several groups of push block cross bar subassembly and chain, wherein the push block cross bar subassembly is connected and fixed with chain through chain live buckle at both ends (as shown in Figure 1 、 Figure 2 ), and the push block cross bar subassembly is composed of support, cross bar and push block, and the push block is connected to cross bar by bolt (as shown in Figure 3 ), and support and cross bar are connected by bolt (as shown in Figure 4 、 Figure 5 ).

[0003] Since the screw hole matched with support and cross bar is clearance hole (as shown in Figure 6 、 Figure 7 ), with the long-time operation of equipment, under the action of continuous load wear and thermal expansion and contraction, bolt loosens, so that support moves within the aperture range of clearance hole, push block cross bar subassembly deforms, causes support to rub with internal guide rail of ZB48A packer, especially when support displaces to both ends (as shown in Figure 8 、 Figure 9 ), the overall length of push block cross bar subassembly is lengthened, so that chain pitch changes, and the pitch of each chain is elongated to different degrees, causes cigarette group in ZB48A packer to be faster or slower in conveying process relative to previous conveying action, cannot match with the action of remaining components in ZB48A packer, produces defective products, and seriously causes each process of product to be unable to normally cooperate.

[0004] Therefore, the first push chain assembly of ZB48A packer needs to be regularly disassembled and maintained, and push block cross bar subassembly is adjusted, so that push block cross bar subassembly reaches standard state (i.e., chain pitch reaches standard process requirement).But in actual operation, maintenance personnel faces the following difficulties:

[0005] Firstly, since there is lack of special adjustment tool, it is extremely difficult to accurately correct push block cross bar subassembly of first push chain assembly, cannot adjust support and cross bar to the position required by process, can cause support to generate greater friction resistance with guide rail in the passage of ZB48A packer, not only affects the normal operation of equipment, but also can cause equipment to be unable to use due to overheating, and even equipment is damaged.

[0006] Secondly, if the push block crossbar assembly cannot be accurately corrected to the standard state (i.e. the chain pitch reaches the standard process requirement), it will cause the first propulsion chain assembly after installation to have a longer left side or a longer right side.

[0007] In addition, due to the overall heavy weight and long length of the first propulsion chain assembly, manual support is required to ensure smooth installation into the guide rail of the ZB48A packaging machine, so the replacement and installation of the first propulsion chain assembly is time-consuming and laborious each time, and nearly five hours are required for each time of adjustment and disassembly. If the adjustment of a certain push block crossbar assembly is not good, rework is required, which means that more time is spent on adjustment, thereby affecting production efficiency.

[0017] As a preferred scheme of the present application, the first adjusting block (1) further comprises:

[0018] The connecting rod sliding grooves (11) are provided with a plurality of connecting rod sliding grooves (11) which are uniformly distributed in the first adjusting block (1) and are matched with the number of the connecting rods (4), and the connecting rod sliding grooves (11) only penetrate through one side of the first adjusting block (1) and are open, and the connecting rods (4) can move in the connecting rod sliding grooves (11).

[0025] The working principle of the present application is as follows:

[0026] The purpose of the adjusting tool is to correct the push block cross bar assembly (A) to a standard state (i.e., the chain pitch reaches the standard process requirement).

[0027] Because the adjusting base (6) of the tooling is customized according to the push block cross bar assembly (A) of standard length (which can make the chain pitch reach the standard process requirement), after the push block cross bar assembly (A) is placed into the adjusting base (6), the two ends are limited by the clamping groove (61), the overall length of the push block cross bar assembly (A) is limited, and a pushing force is applied from the center of the push block cross bar assembly (A) to the two ends, so that the support (A1) (within the aperture range of the gap screw hole) is prevented from moving excessively to the center of the cross bar assembly (A), and the push block cross bar assembly (A) in the standard state can be obtained by locking by using the bolt (A3).

[0028] After the push block (A4) is removed and the bolt (A3) is loosened, the push block cross bar assembly (A) is placed into the adjusting base (6) and abuts against the baffle (62), and because the push block cross bar assembly (A) is limited by the clamping groove (61) and the baffle (62) and the length of the adjusting base (6), the cross bar (A2) is naturally parallel to the baffle (62), and because the groove at the bottom of the support (A1) is matched with the cross bar (A2), the perpendicularity of the support (A1) and the cross bar (A2) does not change. Similarly, one or more groups of push block cross bar assemblies (A) without the push block (A4) can be placed into and abut against (as shown in Figure 10 、 Figure 17 ).

[0029] Further, the first adjusting block (1) and the second adjusting block (2) are placed into the center of all the push block cross bar assemblies (A) after one end of the first adjusting block (1) and the second adjusting block (2) abut against the support (A1) and one end is pre-tightened by using the handle (as shown in Figure 11 、 Figure 12 、 Figure 13 、 Figure 17 、 Figure 18 ), the two ends of the push block cross bar assembly (A) are limited by the clamping groove (61) and are subjected to the pushing force of the first adjusting block (1) and the second adjusting block (2) under the rebounding action of the rebounding assembly (5), the support (A1) is corrected under the limitation of the clamping groove (61) and the action of the two forces, and the push block cross bar assembly (A) reaches the length required by the process.

[0030] At this time, the cross bar (A2) and the support (A1) are both corrected to the standard matching state, the bolt (A3) is tightened, the push block cross bar assembly (A) is corrected, and after the push block cross bar assembly (A) is installed back to the first advancing chain assembly, the chain pitch of the first advancing chain assembly can reach the standard process requirement.

[0031] The tooling has the following beneficial effects:

[0032] 1. Precise adjustment, improve maintenance efficiency, reduce maintenance cost: the traditional adjustment method is often not accurate due to the lack of special tools, and needs to be adjusted repeatedly, which is time-consuming and laborious. The utility model can accurately adjust one or more groups of push block cross rod assemblies at a time, improving the maintenance efficiency. At the same time, due to the accurate adjustment, the rework frequency is reduced, and the maintenance cost is reduced.
