Description

Technical Field

[0001] The invention belongs to a rotating equipment matching device in a food processing machine, in particular to a tumbling machine. Background Art

[0002] The tumbler is a key equipment for deep processing of meat equipment, and the tumbler barrel cover is an important component of the tumbler. According to the operation mode of opening and closing the cover, the barrel cover is divided into three categories: manual, semi-automatic, and fully automatic. The current production is gradually tending towards automation. The advantage of the fully automatic barrel cover is that it can be operated with one button and is easy to realize automatic control. With the increasing attention paid by the society to the labor intensity of the operator, the fully automatic barrel cover has been more and more widely used, and there is a trend of gradually replacing manual and semi-automatic barrel covers. To realize the fully automatic opening and closing of the barrel cover, a flap system composed of a barrel cover, a pressure arm, and a drive is required. The simplest connection between the barrel cover and the pressure arm device is a rigid connection, which is also the connection method of most barrel covers at present. Although this connection method is simple, the biggest problem is that there is an additional force caused by the coaxiality deviation between the barrel cover and the rotation center of the tumbler barrel during operation, commonly known as "different forces". When the tumbler is running, the barrel cover is pressed against the tumbler barrel mouth and rotates with the barrel. Because the tumble kneading barrel usually runs continuously, this additional force is extremely destructive under the action of fatigue stress. In severe cases, the bearing seat welded on the barrel cover will be torn apart. In addition, the bearings, oil seals and other parts in the barrel cover bearing seat are easily damaged in the short term under the action of the additional force, causing the meat in the barrel to be contaminated by lubricating oil, causing great losses to users. This problem has been an inherent problem that has plagued the industry for many years, and domestic and foreign counterparts have been studying and solving it for a long time. Although other floating or semi-floating barrel cover devices have appeared before, they are not very mature, either with poor effects or complicated and bulky structures, high costs, and inconvenient manufacturing and operation. Summary of the invention

[0003] Based on the above problems, the present invention provides a full-floating device for a tumbling barrel cover, in which the barrel cover as a whole is suspended in the required omnidirectional elastic environment, and there is no "stirring" in any direction during operation; the service life of bearings, oil seals and other parts in the barrel cover bearing seat is greatly extended, thereby significantly extending the trouble-free operation time of the entire machine.

[0004] The technical solution adopted by the present invention is as follows:

[0005] The fully floating barrel cover of the tumble kneading machine has a torsion shaft installed on the barrel cover, and two pressure fork arms symmetrical to the center of the barrel cover are installed on the torsion shaft; a torsion shaft sleeve is installed on the torsion shaft, and the torsion shaft sleeve is located on the outside of the pressure fork arm; the torsion shaft sleeve and the pressure fork arm are fixed by screws; the lower part of the pressure fork arm is fixed with a handle rod with a bearing seat through a pair of hinge seats; the bearing seat cooperates with the bearing and other parts on the barrel cover; among them,

[0007] The vertical adjustment device includes a push pin, a push pin sleeve, and a vertical adjustment spring; a push pin with a sliding fit is inserted into the upper part of the inner hole of the push pin sleeve, one end of the push pin is against the bottom of the hinge seat, and the other end is connected to one end of the vertical adjustment spring; a vertical adjustment screw is installed at the other end of the vertical adjustment spring;

[0008] The handle rod has one end fixed to the bearing seat, and the other end is located in the hinge seat and supported by the joint bearing in the hinge seat; a horizontal adjustment spring is arranged in the hinge seat; a groove is arranged at the outer end of the handle rod, one end of the horizontal adjustment spring is against the bottom surface of the groove, a horizontal adjustment screw is installed at the outer side of the hinge seat, and the horizontal adjustment screw is fixed to the other end of the horizontal adjustment spring; a screw hole is arranged on the side of the handle rod;

[0009] A side block is fixed to one side of the hinge seat by screws; a pair of vertical and interconnected center holes are opened on the side block, namely a horizontal hole and a vertical hole; the sleeve located in the horizontal hole is fixed to the end face of the screw hole on the side of the handle by screws; the vertical hole is equipped with an offset spring and an adjusting bolt. A sliding sleeve is placed on the sleeve and the sleeve is slightly higher than the sliding sleeve, so that after the screw presses the sleeve tightly, the sliding sleeve can still rotate freely;

[0010] The lower side of the sliding sleeve is milled into a plane; the upper end of the eccentric load spring is lowered to the lower side of the sliding sleeve, and the other end is equipped with an eccentric load bolt.

[0011] Furthermore, a cross block is fixed on one side of the torsion sleeve; an inclined block is fixed on one side of the pressure fork arm; the cross block is located above the inclined block, and the distance between the cross block and the inclined block is adjusted by a screw to achieve fine adjustment of the pressure arm fork swing angle.

[0012] Furthermore, a support plate is installed between the pressure fork arms, and a through hole is opened in the center of the support plate.

[0013] Furthermore, the bearing seat and the cross plate do not contact each other.

[0014] Furthermore, the sleeve is higher than the sliding sleeve by at least 0.1 mm.

[0015] The fully floating barrel cover of the tumbling machine of the present invention is characterized in that the torque output by the driving device (which may be a reducer, an oil cylinder, an air cylinder, etc.) is transmitted to two torsion shaft sleeves 14 which are fixedly connected to the torsion shaft and are symmetrical relative to the barrel cover through the torsion shaft, and the torsion shaft sleeves are located on the outer side of the pressure fork arm; a horizontal block is fixed on one side of the torsion shaft sleeve, and an inclined block is fixed on one side of the pressure fork arm; the swing angle of the pressure arm fork is fine-tuned by adjusting the distance between the horizontal block and the inclined block by screws, so that the barrel cover and the barrel mouth of the tumbling machine can be optimally matched; after adjustment, the two pressure arm forks and the torsion shaft sleeves are respectively locked with screws.

[0016] The lower ends of the two pressure arm forks are respectively provided with fork openings, and the fork openings form two fork legs, and the fork legs are respectively slidably matched with the grooves opened on the two side surfaces of the hinge seat.

[0017] Two baffles are installed at the lower end of the fork opening, that is, the lower ends of the two fork legs are equipped with baffles. The baffles not only seal the two fork openings, but also can be used as a base for installing the vertical adjustment device.

[0018] The top of the inner hole of the ejector sleeve in the vertical adjustment device is inserted with a sliding ejector pin, and the bottom is supported by a vertical adjustment spring to support the weight of the barrel cover. The spring force can be adjusted through the lowest vertical adjustment screw to ensure the centering position of the barrel cover and the up and down floating during operation. After the ejector sleeve is put on the washer, the cross plate with holes at both ends is installed and locked with round nuts. The thickness of the washer should ensure that the bearing seat of the barrel cover will not touch the upper plane of the cross plate when the barrel cover is in operation. A support plate is provided between the two pressure arm forks, which plays a reinforcing role on the one hand, and on the other hand, its central through hole is just used to pass the vacuum hose on the bearing seat.

[0019] A pair of handles are welded on both sides of the bearing seat so that the entire barrel cover is supported by the two handles. The two handles are supported by joint bearings installed in the hinge seat respectively, and play the role of swinging and floating in the front and back and left and right directions. The outer ends of the two handles are respectively supported by transverse springs 19 installed in the hinge seat and can be centered by transverse adjustment screws. When the barrel cover is in operation, the two transverse adjustment springs play the role of floating in the left and right directions. Two oil seals protect the bearings and other parts in their respective hinge seats from being corroded by dust and moisture. A screw hole is opened on the side of the handle. After the outer circle of the sleeve is covered with a sliding sleeve, a screw 31 is inserted into the center hole of the sleeve and the sleeve is tightened on the end face of the screw hole on the side of the handle. The sleeve is slightly higher than the sliding sleeve, so that the sliding sleeve can still rotate freely after the screw presses the sleeve. The two side blocks are respectively fixed to the side of the hinge seat with screws. A plane is milled on the lower side of the sliding sleeve. After the upper end of the eccentric load spring installed in the side block presses against the plane, an adjustable reverse torque is provided to the handle rod through the lower eccentric load bolt to balance the eccentric load of the barrel cover and prevent the barrel cover from flipping and falling around the axis of the handle rod.

[0020] The whole barrel cover of the present invention is supported by two handles on the bearing seat, and the connection between the handle and the pressure arm fork is realized by a hinge seat, a joint bearing and three pairs of springs arranged in different directions to achieve omnidirectional floating. It is equivalent to the barrel cover as a whole suspended in the required omnidirectional elastic environment, so there is no "strange force" in any direction during operation.

[0021] The invention has a compact structure, low cost and convenient assembly. It can realize floating in any direction, and is provided with adjusting screws in all directions, which is convenient for adjustment. It completely eliminates the additional force caused by the coaxiality deviation when the barrel cover runs with the tumbling barrel, greatly prolongs the service life of the bearings, oil seals and other parts in the barrel cover bearing seat, thereby significantly prolonging the trouble-free operation time of the whole machine.
