Description

Technical Field

[0001] This utility model belongs to the technical field of packaging and printing equipment, and relates to an upper pressure transmission device for a heat sealing and gluing machine. Background Technology

[0002] During operation, carton gluing machines typically use conveyor belts to transport cartons, which must meet the following requirements. Firstly, especially in high-speed gluing machines, the cartons need to be transported stably and efficiently. Secondly, it's crucial to ensure that the cartons are not affected by subsequent processes such as trimming, pre-folding, and heating during transport. Therefore, in most applications, a conveyor pressure device is required.

[0003] Typical pressure transmission devices consist of a belt combined with guide pulleys, forming an upper pressure belt. In this configuration, the distance between the upper and lower pressure belts is fixed and cannot be adjusted. Therefore, paper jams or clogging are prone to occur when handling cartons of varying thicknesses. Furthermore, the pressure rollers of the transmission device are easily damaged at high speeds, affecting the production efficiency of the carton gluing machine. Utility Model Content

[0004] The purpose of this invention is to provide an upper pressure transmission device for a heat sealing box gluing machine, which solves the problem that existing upper pressure transmission devices cannot perform adaptive adjustment.

[0005] The technical solution adopted in this utility model is an upper pressure transmission device for a heat sealing box gluing machine, including a clamping plate, guide plates movably fixed on both sides of the clamping plate, a lower guide wheel fixedly connected to the bottom of the guide plate, an upper guide wheel movably connected to the top of the guide plate, and several rotating lifting mechanisms provided at the bottom of the clamping plate. A transmission belt is wound around the upper guide wheel, the lower guide wheel, and the rotating lifting mechanisms. The clamping plate, the guide plate, the lower guide wheel, and the rotating lifting mechanisms are on the same plane. The guide plate can move in a direction perpendicular to the clamping plate. The upper guide wheel is connected to the guide plate through a rotating shaft and can rotate around the rotating shaft.

[0006] The features of this utility model also include:

[0007] The guide plate has a connecting part on its edge, and the connecting part has a through hole; the clamp plate has a protrusion on its edge, and the protrusion has a threaded hole. The through hole is fitted with an adjusting bolt, which is compatible with the threaded hole. The through hole and the threaded hole are opened in a direction perpendicular to the long side of the clamp plate and are located in the plane of the clamp plate and the guide plate.

[0008] The rotating foot-lifting mechanism includes a fixed plate fixed to the bottom of the clamping plate. The fixed plate has a groove with a spring installed inside. A connector is hinged to the bottom of the fixed plate. The spring abuts against the connector, and several bearings are installed on the connector.

[0009] The connector is a thin connector. One side of the connector is hinged to the fixed plate, and the other side of the connector has a connecting plate with several bearings mounted on it.

[0010] The bottom of both sides of the clamp is provided with a rotating lifting mechanism, and the opposite rotating lifting mechanisms are connected by the same rotating fulcrum.

[0011] Each rotating foot mechanism is equipped with four bearings.

[0012] A tensioning wheel mechanism is fixedly connected to the top of the clamping plate. The transmission belt forms a complete motion trajectory through the tensioning wheel mechanism, the upper guide wheel, the lower guide wheel, and the rotating lifting mechanism.

[0013] The tensioning wheel mechanism includes a tensioning support plate fixed to the upper part of the clamping plate, two driven wheels fixed on the tensioning support plate, and a transmission belt wound around the driven wheels. One driven wheel moves in the forward direction, and the other driven wheel moves in the reverse direction.

[0014] An auxiliary positioning wheel is fixedly connected to the top of the clamping plate, and the auxiliary positioning wheel is close to the upper guide wheel.

[0015] The height of the contact point between the auxiliary positioning wheel and the transmission belt is lower than the height of the contact point between the upper guide wheel and the transmission belt.

[0016] Compared with existing technologies, the pressure transmission device for the heat-sealing box gluing machine provided by this utility model, by setting the clamping plate and guide plate to be movably connected, allows for the setting of the position and direction of the upper guide wheel as needed, thus realizing free adjustment of the transmission belt gap. Simultaneously, the optimized mechanical structure design incorporates a rotating lifting mechanism, increasing the pressure transmission area and strengthening the pressure on the transmission belt. This allows the box sheets to freely adjust the gap during movement, reducing the likelihood of paper clogging and damage, significantly improving the production efficiency and quality of the box gluing machine. The transmission belt is also less prone to curling or breakage, reducing maintenance and replacement frequency, thus increasing production efficiency and saving product costs.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the heat-sealing box gluing machine of this utility model is mainly composed of components such as clamping plate 1, guide plate 2, upper guide wheel 3, lower guide wheel 4, rotating lifting mechanism 5, transmission belt 8, tensioning wheel mechanism 7, and auxiliary positioning wheel 9.

[0022] The connection between the guide plate and the clamping plate is as follows: a connecting part is provided at the edge of the guide plate 2, and a through hole is provided on the connecting part; a protrusion is provided at the edge of the clamping plate 1, and a threaded hole is provided on the protrusion. An adjusting bolt 6 is provided on the through hole, and the adjusting bolt 6 is adapted to the threaded hole. The through hole and the threaded hole are opened in a direction perpendicular to the direction of the long side of the clamping plate 1 and are located in the plane of the clamping plate 1 and the guide plate 2.

[0023] like Figure 2 As shown, rotating foot-lifting mechanisms 5 are respectively provided on the bottom of both sides of the clamping plate 1. The rotating foot-lifting mechanism 5 includes a fixed plate 51 fixed to the bottom of the clamping plate 1. A groove 52 is provided on the fixed plate 51, and a spring is provided in the groove 52. A connecting piece 53 is hinged to the bottom of the fixed plate 51. The spring abuts against the connecting piece 53. The connecting piece 53 is a thin connecting piece. One side of the connecting piece 53 is hinged to the fixed plate 51, and the other side of the connecting piece 53 is hinged to a connecting plate 55. A bearing 54 is installed on the connecting plate 55.

[0024] The opposing rotating foot mechanisms 5 are connected by the same pivot point, thus forming a buffer frame for the pressure transmission on the clamping plate 1. The opposing rotating foot mechanisms 5 allow for adaptive adjustment to different sized cassette pieces, making them easy to operate. Each rotating foot mechanism 5 is equipped with four bearings 54, providing better stability to the transmission belt 8 on the clamping plate 1 during movement.

[0025] Meanwhile, the rotating lifting mechanism 5 is an important component in the design of this utility model. The rotating lifting mechanism 5 increases the pressure transmission area, resulting in more stable pressing effects when pressing cardboard boxes of different heights and sizes. Because the small contact area between the rotating lifting mechanism 5 and the cardboard box is less likely to damage the box, it is easy to maintain, simple, and durable during machine production.

[0026] Meanwhile, a tensioning wheel mechanism 7 is fixedly connected above the clamping plate 1. The tensioning wheel mechanism 7 is fixed to the upper part of the clamping plate 1, and the transmission belt 8 forms a complete motion trajectory through the tensioning wheel mechanism 7, the upper guide wheel 3, the lower guide wheel 4, and the rotating lifting mechanism 5. The tensioning wheel mechanism 7 consists of a tensioning support plate 71 and a driven wheel 72. The driven wheel 72 has two directions, forward and reverse, which can better realize the tensioning and transmission of the belt.

[0027] The auxiliary positioning wheel 9 is close to the upper guide wheel 3, and the height of the contact position with the transmission belt 8 is lower than the height of the contact position between the upper guide wheel 3 and the transmission belt 8. The auxiliary positioning wheel 9 can not only avoid the problem of the belt being skewed during transportation, which affects the chain drive, but also avoid the phenomenon of most objects getting stuck when they contact the belt, thus ensuring the smooth operation of the entire transmission belt 8.

[0028] Since the clamping plate 1, guide plate 2, lower guide wheel 4, and rotating foot mechanism 5 are on the same plane, the guide plate 2 can move in a direction perpendicular to the clamping plate 1. The upper guide wheel 3 is connected to the guide plate 2 through a rotating shaft, and the upper guide wheel 3 can rotate around the rotating shaft. In this way, the stability of the transmission belt 8 can be maintained while ensuring automatic adaptability.

[0029] The device uses rotating lifting mechanisms 5 at the bottom of both sides of the clamping plate 1, connected by the same rotating fulcrum, to form the frame for pressing and transmitting on the clamping plate 1. The relative arrangement of the rotating lifting mechanisms 5 allows for the processing of other box shapes and is easy to operate. Each rotating lifting mechanism 5 is equipped with four bearings 54, which gives the transmission belt 8 on the clamping plate 1 better stability during movement.

[0030] Meanwhile, a tensioning wheel mechanism 7 is fixedly connected above the clamping plate 1 of the device. The tensioning wheel mechanism 7 consists of a tensioning support plate 71 and a driven wheel 72, and is used to tension and drive the transport belt. The auxiliary positioning wheel 9 is close to the upper guide wheel 3 to control the position of the belt and prevent objects from contacting the belt and causing jamming.

[0031] When using this device, the pressure transmission of the discs is achieved through the transmission belt 8, upper guide wheel 3, lower guide wheel 4, rotating lifting mechanism 5, and auxiliary positioning wheel 9. This maintains the stability of the transmission belt 8 while enabling the machine to adapt, ensuring smooth operation of the entire device's transmission.

[0032] The advantages of the pressure transmission device for the heat-sealing gluing machine provided by this utility model are its simple structure, ease of maintenance and adjustment, smoother transport by the transmission belt 8, more stable pressure, higher production efficiency, reduced maintenance and replacement frequency, and cost savings. During use, it avoids the problems of paper jams or blockages that easily occur when handling cartons of different thicknesses due to the fixed and unadjustable gap between the upper and lower pressure belts. Simultaneously, it reduces the risk of damage to the pressure rollers of the transmission pressure device at high speeds, thus reducing the impact on the gluing machine's production efficiency. The combined design of the tensioning wheel mechanism 7 and the rotating foot mechanism 5 provides excellent resettlement and reliability, avoiding the unstable operation of traditional clamping plates 1 and guide wheels during use, reducing vibration and resistance during movement, reducing dynamic friction, and significantly reducing wear and tear.

[0033] Overall, the device employs a relatively common design, thereby enabling adjustable pressure gap between the transmission device and its lower belt. Furthermore, the rotating foot mechanism of the upper pressure belt allows for free adjustment of the gap during the movement of the paper tray, reducing the likelihood of paper clogging. Therefore, this invention possesses excellent technical effectiveness and practical value.
