Description

Technical Field

[0001] The utility model relates to the field of sealing machines, in particular to a sealing machine with convenient transmission. Background Art

[0002] Sealing machine is an automatic sealing device that can heat-seal low-density polyethylene bags, aluminum foil bags, paper-plastic composite bags and other products. The general sealing machine is mainly composed of two parts: the sealing host and the conveyor table. The sealing host is used to seal the product, and the conveyor table is mainly responsible for the transmission of the product to be sealed and the separation of the sealed product to the outside of the machine. At the same time, the transmission work of the conveyor table is generally linear transmission. At the same time, when the conveyor table is working, its power output is connected to the conveyor table by the output shaft on the sealing host, so as to realize the movement of the belt on the conveyor table, that is, the transmission of the product to be sealed on the conveyor table or the transmission of the sealed product is a transmission action performed by the movement of the belt.

[0003] The transmission part of the conveyor platform of some sealing machines currently on the market involves the front roller, the rear roller distributed on the ends of both sides of the belt, and the middle shaft located between the front and rear rollers. The front and rear rollers are used to support the belt and drive the belt to move. The middle shaft is connected to the rear roller by a V-belt. At the same time, the middle shaft is connected to the output shaft on the sealing host and rotates synchronously with the output shaft on the sealing host. That is, the conveying force of the output shaft is transmitted to the middle shaft and, through the action of the V-belt, drives the rotation of the rear roller and transmits it to the belt, thereby realizing the transmission action of the belt.

[0004] However, during the production process of the above-mentioned conveyor table driven by the central shaft, it was found that its installers generally need to use tools first to ensure that the central shaft and the rear roller can remain parallel after installation, that is, the V-belt, the central shaft and the rear roller are distributed in an I-shape after installation, and the V-belt after installation is always in a tensioned state (regardless of whether the subsequent sealing machine is in working condition, the V-belt is tensioned), which makes the V-belt loose after long-term use or after a period of use. As a result, during the transmission process, there will be a synchronization between the central shaft and the rear roller, and even when the V-belt is too loose, the central shaft cannot drive the rear roller to rotate, which makes the transmission process inaccurate and unreliable. Summary of the invention

[0005] In view of the above-mentioned deficiencies, the utility model provides a sealing machine which has reliable transmission, convenient transmission process and improved production efficiency.

[0006] In order to achieve the above purpose, the utility model adopts a sealing machine with convenient transmission, including a sealing machine main body and a conveying platform distributed on one side of the sealing machine main body, the conveying platform including a support frame, a front roller and a rear roller limited in the support frame, and a conveying belt supported by the front and rear rollers, the sealing machine main body is formed with an output shaft for driving the conveying platform to perform a transmission action in the direction of the conveying platform, the inner side of the rear roller includes a rear roller shaft that rotates synchronously with the rear roller, one side of the rear roller shaft has an output shaft end facing the output shaft of the sealing machine main body, and the shaft end extends in the direction of the output shaft of the sealing machine main body and is connected to the output shaft, so as to form an output force of the sealing machine main body that is transmitted to the conveying platform through the rear roller shaft.

[0007] The beneficial effect of the above structure is that: by involving the rear roller shaft on the rear roller, and extending the shaft end of the rear roller shaft facing the output shaft to one side of the output shaft, and synchronously connecting it with the output shaft of the sealing machine body, the output force of the sealing machine body can be transmitted to the conveying platform through the rear roller shaft, that is, by transmitting the output force to the conveying platform in this way, the transmission is reliable, and the existing middle shaft for outputting the output force on the conveying platform can be eliminated, and the need for secondary transmission of the output force when the middle shaft is involved is avoided. In addition, during the transmission process, the loosening of the V-belt after a period of use may occur, causing the normal use of the conveying platform to be affected. In addition, compared with the existing production process, the sealing machine involved in the utility model can be greatly simplified, that is, the production efficiency is improved.

[0008] The utility model is further configured such that the axis of the rear roller shaft and the axis of the output shaft of the sealing machine body are distributed on the same straight line.

[0009] The above arrangement can avoid the problem that the axis of the rear drum shaft and the axis of the output shaft of the sealing machine body do not align, affecting the reliability of the connection between the two, and also ensure the rationality of the design of the sealing machine involved in the utility model.

[0010] The utility model is further configured such that a limiting groove is provided on the shaft end of the rear roller shaft relative to the shaft end extending in the direction of the output shaft of the sealing machine body, a connecting groove is provided on the output shaft of the sealing machine body, a transmission sleeve is provided between the output shaft and the shaft end of the rear roller shaft, one end of the transmission sleeve is sleeved on the output shaft, and the other end is sleeved on the shaft end of the rear roller shaft, and through the connecting groove and the limiting groove, the transmission sleeve is respectively connected to the shaft ends of the output shaft and the rear roller shaft, and transmission between the output shaft of the sealing machine body and the rear roller shaft is formed.

[0011] Through the above arrangement, the rear roller shaft and the output shaft of the sealing machine body can be reliably connected, and the transmission between the two is reliable after the connection.

[0012] The utility model is further configured such that roller fixing plates are formed on both sides of the rear roller, and extension plates are formed on the two roller fixing plates toward the front roller direction, and the support frame includes a support plate for abutting against the inner upper surface of the belt, two side plates distributed on both sides of the conveyor platform, and a bottom plate for installing the conveyor platform, one side of the two side plates extends to the direction of the front roller and forms an external cover of the front roller and is hidden on the inner side of the two side plates, and the other side of the two side plates extends to the direction of the rear roller and is limited to the extension plate.

[0013] Through the above arrangement, the support frame used for supporting the conveying platform can be reliably installed at the position of the rear roller after the two side plates are installed. At the same time, after the installation, it will not affect the extension of the rear roller axis toward the output axis, and will not affect the output and transmission of the output force on the sealing machine body, thereby ensuring the reliability of the transmission of the sealing machine body.
